5x+17+9x+23=180 solve for x

Correct option:

[tex]\boxed{x-y=P-Q}[/tex]

Given that the line we are looking for is parallel to g, then the slope of that line and g is the same, therefore:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ (x_{1},y_{1})=(-3,2) \\ \\ (x_{2},y_{2})=(0,5) \\ \\ \\ m=\frac{5-2}{0-(-3)}=1[/tex]

So we can write the point-slope form of the equation of the line as follows:

[tex]y-y_{0}=m(x-x_{0}) \\ \\ (x_{0},y_{0})=(P,Q) \\ \\ \\ y-Q=1(x-P) \\ \\ y-Q=x-P \\ \\ \\ Arranging: \\ \\ P-Q=x-y \\ \\ \boxed{x-y=P-Q}[/tex]

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope and b is the y intercept.

Line g passes through (-3,2) and (0,5). hence:

Two lines are parallel if they have the same slope. Hence:

Line parallel to line g has a slope of 1. Since it passes through (P, Q), hence:

[tex]y-y_1=m(x-x_1)\\\\y-Q=1(x-P)\\\\y-Q=x-P\\\\x-y=P-Q[/tex]

The equation of a line that is parallel to line g that contains (P, Q) is x - y = P - Q

The value of -36 divided by (-4/9) is 81, which is found by multiplying -36 with the reciprocal of (-4/9), giving the result 324/4, which simplifies to 81.

To find the value of -36 divided by (-4/9), you can think of division by a fraction as multiplication by its reciprocal. So, the problem changes from division to multiplication: -36 * (-9/4). To solve this:

First, multiply the numerators: -36 * -9 = 324.

Then, multiply the denominators: 1 * 4 = 4.

Now, divide 324 by 4 to get 81.

Therefore, the value of -36 divided by (-4/9) is 81.

Answer:

x=40 and y= 60

Step-by-step explanation:

step:1

Let 'x' and 'y' are two numbers

given data the sum of two numbers is 100

x+y = 100......(1)

Given difference of two numbers are

x - y = -20 ......(2)

Step :2

solving the equation (1) and (2)

adding the equations (1) and (2)

x+y+x-y=100-20

cancelling 'y' terms are

2 x = 80

dividing "2" on both sides, we get

x = 40

Step :3

substitute x = 40 in equation (1)

x + y =100

40 + y = 100

subtracting "40" on both sides, we get

40 + y - 40 = 100 -40

y = 60

Final answer:-

The two numbers are x = 40 and y= 60

Answer: 0.11

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.

So we can think of 11% as the ratio 11 to 100 or 11 divided by 100.

Dividing by 100 moves the decimal point 2 places to the left so 11 divided by 100 would move the decimal point 2 places to the left which would give us .11 or 0.11.

So 11% can be written as the decimal 0.11.

Answer:

The area of the composite figure = 12.785 square units

Step-by-step explanation:

The figure composite of :

A ⇒ Rectangle with coordinates (0,0) , (0,5) , (2,5) and (2,0)

B ⇒ Rectangle with coordinates (2,0) , (2,1) , (4,1) and (4.0)

C ⇒ Quarter of a circle with coordinates (2,1) , (2,2) and (3,1)

Area of A: Length = 5 and Width =2

Area of A = Length times the width = 5*2 = 10 square units

Area of B: Length = 2 and Width =1

Area of B = Length times the width = 2*1 = 2 square units

Area of C: radius = 1

Area of C = 0.25 * pi * r² = 0.25 * 3.14 * 1² = 0.785 square units

Answer:  1.75 cubic feet concrete is needed.

Step-by-step explanation:

Alright, lets get started.

The volume of the pillar is : [tex]\pi r^2h[/tex]

We have given the height is 5 feet.

We have given the diameter is 4 inches.

So the radius will be : [tex]\frac{4}{2}=2 \ inches[/tex]

Converting inches into feet.

The radius will be : [tex]\frac{2}{12} \ feet[/tex] [tex]= 0.167 feet[/tex]

So the volume of the cylinder will be : [tex]\pi * 0.167^2*5[/tex]

So the volume of the cylinder will be : [tex]0.4380 \ cubic \ feet[/tex]

As there are 4 pillars, so total volume will be : [tex]4*0.4380[/tex]

So, total volume will be : [tex]1.75 \ cubic \ feet[/tex]

Hence 1.75 cubic feet concrete is needed.   :   Answer

Answer:

Perimeter of each triangles are equivalent to 15.4 inches.

Step-by-step explanation:

Given:

A rectangle :

Length of the rectangle = 5 inches

Width of the rectangle =4 inches

As Bridget cuts it from one corner to the other corner,its forms two right angled triangle.

The diagonal will be treated as the hypotenuse.

Lets say that the length of the hypotenuse is 'x'.

Using Pythagoras formula:

⇒ [tex](hypotenuse) = \sqrt{(perpendicular)^2+(base)^2}[/tex]

Plugging the values:

⇒ [tex]hypotenuse = \sqrt{5^2+4^2}[/tex]

⇒ [tex]hypotenuse = \sqrt{25+16}[/tex]

⇒ [tex]hypotenuse =\sqrt{41}[/tex]

⇒ [tex]hypotenuse = 6.40[/tex]  inches

Now we have to find the perimeter :

Perimeter = Summation of length of all sides.

So,

Perimeter  of each triangle = (length + width + hypotenuse)

⇒ [tex]Perimeter =(5+4+6.4)[/tex]

⇒ [tex]Perimeter =15.4[/tex]  inches

Perimeter of each triangle, as they are equally sized are same that is   15.4 inches.                              

Answer:

30, 42

Step-by-step explanation:

You add 2 to the additional 2 you started with

0+2=2

2+(2x2)=6

6+(2x3)=12

The required next two-term of the sequence is 30 and 42.

Given that,
To determine the pattern and next two-term of numbers 0, 2, 6, 12, 20.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
The given sequence is,
0, 2, 6, 12, 20,
a0 = 0,
a1 = 2
nth term an = a(n - 1) + 2(n - 1)
For 6th term
n = 6
6th term = a(6 - 1) + 2(6 - 1)
        a6 = a5 + 10
        a6 = 20 + 10
        a6  = 30
7th term,
an = a(n -1) + 2 (n - 1)
a7 = a6 + 2*6
a7 = 30 + 12
a7 = 42

Thus, the required next two-term of the sequence is 30 and 42.

Final answer:

To find the area of the basement, we started with the given perimeter of 130 feet and the known length of 25 feet and solved for the missing width. Once we determined the width was 40 feet, we used the formula for the area of a rectangle (Area = length × width) to calculate that the basement's area is 1000 square feet.

Explanation:

To solve the question regarding the area of a rectangle where the length is 25 feet and the perimeter is 130 feet, we must first deduce the width of the rectangle using the perimeter formula: P = 2l + 2w (where P is the perimeter, l is the length, and w is the width). Since we know the perimeter (P) and the length (l), we can rearrange this formula to solve for the width (w).

The perimeter formula is expressed as:

130 = 2(25) + 2w

130 = 50 + 2w

2w = 130 - 50

2w = 80

w = 40 feet

Now that we have both the length and the width, we can calculate the area of the rectangle using the formula Area = length × width.

Therefore, the area of the rectangle is:

Area = 25 feet × 40 feet
Area = 1000 square feet

Answer:

[tex](x+5)^{2}=-4(y+3)[/tex]

Step-by-step explanation:

Given:

Focus point = (-5, -4)

Vertex point = (-5, -3)

We need to find the equation for the parabola.

Solution:

Since the x-coordinates of the vertex and focus are the same,

so this is a regular vertical parabola, where the x part is squared. Since the vertex is above the focus, this is a right-side down parabola and p is negative.

The vertex of this parabola is at (h, k) and the focus is at (h, k + p). So, directrix is y = k - p.

Substitute y = -4 and k = -3.

[tex]-4 = -3+p[/tex]

[tex]p=-4+3[/tex]

[tex]p=-1[/tex]

So the standard form of the parabola is written as.

[tex](x-h)^{2}=4p(y-k)[/tex]

Substitute vertex (h, k) = (-5, -3) and p = -1 in the above standard form of the parabola.

So the standard form of the parabola is written as.

[tex](x-(-5))^{2}=4(-1)(y-(-3))[/tex]

[tex](x+5)^{2}=-4(y+3)[/tex]

Therefore, equation for the parabola with focus at (-5,-4) and vertex at (-5,-3)

[tex](x+5)^{2}=-4(y+3)[/tex]

We know x in f(x) is g(x) which is 2x^2 because we are to find (fg)(x)
