The length of the base of an isosceles triangle is x. The length of a leg is 3x -4. The perimeter of the triangle is 41. Find x.
Answers
Length of base of isosceles triangle, x = 7
Step-by-step explanation:
Step 1: Given base of isosceles triangle, x = 7 and perimeter = 41Length of one leg = 3x - 4. Since two sides, other than the base of an isosceles triangle are equal, the length of the other leg = 3x - 4.
Step 2: Formula for perimeter of triangle = length of sidesStep 3: Substitute values of sides in the formula⇒ 41 = x + (3x - 4) + (3x - 4) = x + 2(3x - 4)
⇒ 41 = x + 6x - 8
⇒ 41 = 7x - 8
⇒ 49 = 7x
⇒ x = 7

Where is the vertex of the equation?y = x2 – 18x + 80
Answers
Answer:
vertex = (9, - 1 )
Step-by-step explanation:
Given a quadratic in standard form, y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = x² - 18x + 80 ← is in standard form
with a = 1 and b = - 18, thus
[tex]x_{vertex}[/tex] = - [tex]\frac{-18}{2}[/tex] = 9
Substitute x = 9 into the function for corresponding value of y
y = 9² - 18(9) + 80 = 81 - 162 + 80 = - 1
Vertex = (9, - 1 )

2 (two-fifths x + 4) = 2 and two-fifths x + 8
Answers
2([tex]\frac{2}{5}[/tex]x + 4) = [tex]\frac{4}{5}[/tex]x + 4 which is the second option is the equivalent expression.
Explanation:
First, we need to calculate the value of two-fifths of x. It means 2 portions out of the five portions of x which equates to [tex]\frac{2}{5}[/tex]x.
Now we calculate the values of the two expresssions on the LHS.
1) 2 (two-fifths x + 2) = 2 ([tex]\frac{2}{5}[/tex]x + 2) = [tex]\frac{4}{5}[/tex]x + 4.
2) (two-fifths x + 4) = 2([tex]\frac{2}{5}[/tex]x + 4) = [tex]\frac{4}{5}[/tex]x + 8.
Now we determine values of the four expressions on the RHS.
1) Two and two-fifths x + 1 = 2[tex]\frac{2}{5}[/tex]x + 1
2) Four-fifths x + 4 = [tex]\frac{4}{5}[/tex]x + 4
3) Four-fifths x + 2 = [tex]\frac{4}{5}[/tex]x + 2
4) Two and two-fifths x + 8 = 2[tex]\frac{2}{5}[/tex]x + 8.
Out of the various LHS and RHS values, the [tex]1^{st}[/tex] LHS value and [tex]2^{nd}[/tex] RHS value is the same. So option 2 is the answer.

Recall that the perimeter of a rectangle is P=2(W+L), where W is the width and L is the length.
The length of a rectangle is 26 feet more than the width. If the perimeter is 60 feet, then what is the length of the rectangle,
Answers
To find the length of the rectangle, use the given information about the width and perimeter. Solve the equations to find the values of the variables and determine the length of the rectangle.
Explanation:To find the length of the rectangle, we can use the information given in the problem. Let's let the width be represented by W and the length be represented by L. We are told that the length is 26 feet more than the width, so we can write the equation L = W + 26. We are also given that the perimeter of the rectangle is 60 feet, so we can write the equation 60 = 2(W + L). We can substitute the value of L from the first equation into the second equation to solve for W. After finding the value of W, we can substitute it back into the first equation to find the value of L.
Let's start with the first equation: L = W + 26. Since we have an equation with two variables, we'll need to use the second equation to solve for the variables. Let's substitute the value of L in the second equation: 60 = 2(W + (W + 26)). We can simplify this equation by combining like terms: 60 = 2(2W + 26). We can distribute the 2 to the terms inside the parentheses: 60 = 4W + 52. We can then subtract 52 from both sides of the equation: 8 = 4W. Finally, we can divide both sides of the equation by 4 to solve for W: W = 2.
Now that we have the value of W, we can substitute it back into the first equation L = W + 26. This gives us: L = 2 + 26. We can simplify this equation to find that L = 28.

What is the equation in standard form for (0,3) and (7,0)
Answers
Answer:
3x + 7y = 21
Step-by-step explanation:
We have value of two points (0,3) and (7,0)
First, let's find the slope of this line. The formula for slope is:
Change in y/Change in x or (y₂ - y₁)/(x₂-x₁)
Where x₁ = 0 x₂= 7 y₁ = 3 y₂ = 0
(y₂ - y₁)/(x₂-x₁)
= (0-3)/(7-0)
=-3/7
Now we can write the equation in point-slope form:
y-y₁ = m(x-x₁)
y - 3 = -3/7(x-0)
y-3=-3x/7
y=-3x/7 + 3
Now let's convert this to standard form, by making the y-intercept by itself:
Ax + By = C
y=-3x/7 + 3
Multiply through by 7
7(y) = 7(-3x/7) + 7(3)
7y = -3x + 21
3x + 7y = 21

Which of the following is a solution to this inequality? y>1/2x+2
A. (1,4)
B. (-1,1)
C. (2,3)
D. (0,2)
Answers
None of the given points are solutions to the inequality.
Explanation:To determine which of the given points is a solution to the inequality y > 1/2x + 2, you need to substitute the coordinates of each point into the inequality and check if the inequality holds true.
Let's start with point (1, 4):
4 > 1/2 * 1 + 2
4 > 1/2 + 2
4 > 2.5 + 2
4 > 4.5
The inequality does not hold, so point (1, 4) is not a solution to the inequality.
Now, let's try point (-1, 1):
1 > 1/2 * -1 + 2
1 > -1/2 + 2
1 > 1.5
The inequality does not hold, so point (-1, 1) is not a solution to the inequality.
Similarly, checking for points (2, 3) and (0, 2), we find that neither of them satisfy the inequality.
Therefore, none of the given points, (1, 4), (-1, 1), (2, 3), or (0, 2), are solutions to the inequality y > 1/2x + 2.

Identify the zeros of f(x) = (x + 9)(x − 4)(6x + 1).
−9, −1 over 6,4
9, 1 over 6, 4
−9, −1 over 6,−4
−9, 1 over 6, −4
Answers
Step-by-step explanation:
We have,
f(x) = (x + 9)(x − 4)(6x + 1)
To find, all zeroes of the given equation = ?
∴ f(x) = (x + 9)(x − 4)(6x + 1)
⇒ (x + 9)(x − 4)(6x + 1) = 0
⇒ x + 9 = 0 or, x − 4 = 0 or, 6x + 1 = 0
⇒ x + 9 = 0 ⇒ x = - 9
⇒ x − 4 = 0 ⇒ x = 4
⇒ 6x + 1 = 0
⇒ 6x = - 1
⇒ x = [tex]\dfrac{-1}{6}[/tex]
∴ x = - 9 , [tex]\dfrac{-1}{6}[/tex], 4
Thus, the required 'option a) - 9 , [tex]\dfrac{-1}{6}[/tex], 4' is correct.
Final answer:
To find the zeros of the function f(x) = (x + 9)(x − 4)(6x + 1), we solve for x in each factor: x = -9, x = 4, and x = -1/6, which means the zeros are -9, 4, and -1/6.
Explanation:
To identify the zeros of a function, you need to find the values of x for which the whole expression equals zero. The function given is f(x) = (x + 9)(x − 4)(6x + 1). To find the zeros, we set each factor equal to zero and solve for x.
(x + 9) = 0 → x = -9
(x − 4) = 0 → x = 4
(6x + 1) = 0 → 6x = -1 → x = -1/6
Therefore, the zeros of the function are -9, 4, and -1/6.

Final answer:
The choice that is NOT equal to the others is C) 2/5, because it is the only positive fraction, while the others represent the negative fraction − 2/5.
Explanation:
The student's question asks which of the given choices is NOT equal to the others. The choices provided include A) − 2/5, B) − 2/5, C) 2/5, and D) 2/ −5. To find the answer, we must compare the values.
Options A and B are the same, which is − 2/5 or negative two-fifths. Option D, which is 2/−5, simplifies to − 2/5 because division by a negative number yields a negative result, making it equivalent to options A and B. However, option C is the only one that is different because it is 2/5, which is positive two-fifths, not negative. Therefore, the answer is C) 2/5 as it is not equal to the other options, which are all negative two-fifths.
Which ordered pair in the form(x,y) is a solution of this equation?
7x-5y=1
A] (-3,-2)
B] (-2,-3)
C] (0,4)
D] (4,0)
Answers
The ordered pair is (-2, -3)
Step-by-step explanation:
Step 1: To find whether an ordered pair is a solution, substitute values of x and y and see whether it satisfies the equation.(-3, -2) ⇒ 7 × -3 - 5 × -2 = -21 + 10 = -11 ≠ 1
(-2, -3) ⇒ 7 × -2 - 5 × -3 = -14 + 15 = 1
(0, 4) ⇒ 0 - 5 × 4 = 20 ≠ 1
(4, 0) ⇒ 7 × 4 - 0 = 28 ≠ 1
So the ordered pair is (-2, -3)
The ordered pair that is a solution to the equation 7x-5y=1 is option B, (-2,-3), as it is the only pair that satisfies the equation when the values are substituted.
Explanation:The question asks which ordered pair is a solution to the equation 7x-5y=1. To find the solution, we simply substitute the x and y values from each ordered pair into the equation and see which pair satisfies the equation.
For option A (-3,-2), let's plug it in: 7(-3) - 5(-2) = -21 + 10 = -11, which does not equal 1.For option B (-2,-3), we get: 7(-2) - 5(-3) = -14 + 15 = 1, which does equal 1. Therefore, this is the correct solution.For option C (0,4), we get: 7(0) - 5(4) = -20, which does not equal 1.Lastly, for option D (4,0), plugging it in gives us: 7(4) - 5(0) = 28, which does not equal 1.So, the ordered pair that is a solution to the equation is option B, (-2,-3).

Answers
The solutions to the quadratic equation 2x^2 - 8x + 7 = 0 are x = 2 + √2 / 2 and x = 2 - √2 / 2 using the quadratic formula.
To solve the equation 2x2 - 8x + 7 = 0, we will use the quadratic formula, where 'x' equals minus 'b', plus-or-minus the square root of 'b' squared minus four 'a' 'c', all over two 'a'. The coefficients in this case are a = 2, b = -8, and c = 7.
First, we calculate the discriminant, which is b2 - 4ac. Substituting our values we get:
(-8)2 - 4(2)(7) = 64 - 56 = 8.
The square root of 8 can be simplified to 2√2, because 8 = 4 × 2 and √4 = 2.
Finally, we substitute the values into the quadratic formula:
x = (-(-8) ± √8) / (2 × 2)
x = (8 ± 2√2) / 4
Dividing each term by 4 gives us:
x = 2 ± √2 / 2
Therefore, the solutions to the equation are:
x = 2 + √2 / 2 and x = 2 - √2 / 2

The completion of a chemical reaction is expressed by the equation
[tex]y = 300 - 4x -x^2[/tex]
where y is the number of seconds needed to complete the reaction and x is the temperature in degrees Celsius at which the reaction occurs.
We have to find the temperature at which the reaction occurs, if the completion time of reaction is 160 seconds.
Putting y = 160
[tex]160 = 300 - 4x -x^2\\x^2 + 4x - 140 = 0\\x^2 + 14x -10x -140 = 0\\x(x+14)-10(x+14)=0\\(x-10)(x+14) = 0\\(x-10) =0, (x+14) =0\\x = 10, x = -14[/tex]
