Answer:

A

Step-by-step explanation:

A horizontal translation of - 3 means to subtract 3 from the original x- coordinate.

A vertical translation of - 3 means to subtract 3 from the original y- coordinate, thus

M(2, 2 ) → M'(2 - 3, 2 - 3 ) → M'(- 1, - 1 ) → A

x = 5

Solution:

Given equation is [tex]x+1=\sqrt{5x+11}[/tex].

[tex]\Rightarrow x+1=\sqrt{5x+11}[/tex]

Squaring on both sides of the equation to remove the square root.

[tex]\Rightarrow (x+1)^2=(\sqrt{5x+11})^2[/tex]

[tex]\Rightarrow (x+1)^2=5x+11[/tex]

Using algebraic identity: [tex](a+b)^2=a^2+2ab+b^2[/tex]

[tex]\Rightarrow x^2+2x(1)+1^2=5x+11[/tex]

[tex]\Rightarrow x^2+2x+1=5x+11[/tex]

Combine all terms in one side of the equation.

[tex]\Rightarrow x^2+2x+1-5x-11=0[/tex]

Arrange like terms together.

[tex]\Rightarrow x^2+2x-5x+1-11=0[/tex]

[tex]\Rightarrow x^2-3x-10=0[/tex]

Now solve by factorization.

[tex]\Rightarrow x^2-5x+2x-10=0[/tex]

[tex]\Rightarrow (x^2-5x)+(2x-10)=0[/tex]

Take common terms on left side of the term.

[tex]\Rightarrow x(x-5)+2(x-5)=0[/tex]

Now, take (x – 5) common on both terms.

[tex]\Rightarrow (x+2)(x-5)=0[/tex]

⇒ x + 2 = 0 (or) x – 5 = 0

⇒ x = –2 (or) x = 5

If we put x = –2 in the given equation,

[tex]-2+1=\sqrt{5(-2)+11}[/tex]

[tex]\Rightarrow-1=1[/tex]

It is false. So, x = –2 is not true.

If we put x = 5 in the given equation,

[tex]5+1=\sqrt{5\times5+11}[/tex]

[tex]5+1=\sqrt{36}[/tex]

[tex]\Rightarrow6=6[/tex]

It is true. So, x = 5 is true.

Hence x = 5 is the solution.

Answer:

The answer is -5.

Answer:

Therefore,

[tex]y=2x+6[/tex] and

[tex]6y=2x+9[/tex] are not Perpendicular.

Step-by-step explanation:

Given:

[tex]y=2x+6[/tex]         ............................Equation of line( 1 )

[tex]6y=2x+9\\y=\dfrac{1}{3}+\dfrac{3}{2}[/tex]     ............................Equation of line( 2 )

Solution:

So the Equations are written in

[tex]y=mx+b[/tex]

Where m is the slope of the line

On Comparing we get

[tex]Slope = m1 = 2[/tex]

[tex]Slope = m2 = \dfrac{1}{3}[/tex]

So for the lines to be Perpendicular.

Product of slopes = - 1

m1 × m2 = -1

So Product of slopes of the given lines are

[tex]m1\times m2=2\times \dfrac{1}{3}=\dfrac{2}{3}[/tex]

Which is not equal to -1

Therefore,

[tex]y=2x+6[/tex] and

[tex]6y=2x+9[/tex] are not Perpendicular.

Answer: 9.84 x 10²

Step-by-step explanation: To write 984 in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.

So here we have 9.84.

Next, count the number of places that we would need to move the decimal point in 9.84 in order to get back to the original number, 984.

Since we would need to move the decimal point two places to the right to get back to the original number, we have an exponent of 2.

Notice that our exponent is positive because we would need to move the decimal point to the right.

Now, scientific notation is always expressed as a power of 10. In this case, we have 10 to the 2nd or 10 to the 2nd power.

So 984 can be written in scientific notation as 9.84 x 10².

9 * 44 =

9 (40 + 4) =

9(40) + 9(4) =

360 + 36 = 396

Final answer:

To mentally calculate 9 x 44, use the distributive property by multiplying 9 by 40 and 9 by 4, then adding the results to get 396.

Explanation:

The question asks how to mentally calculate 9 x 44 using the distributive property. To do this, you can break down the multiplication into simpler parts. First, use the distributive property to express 44 as the sum of 40 and 4. Multiply 9 by each part:

9 x 40 = 360

9 x 4 = 36

Then, add the two results together:

360 + 36 = 396

So, 9 x 44 equals 396.

Answer:

XAE and EAY form a linear pair.

done

DE and XY are perpendicular.

XAE and DAY are vertical angles.

Step-by-step explanation:

This answer explains the mathematical concepts related to angles and lines i.e., vertical angles, perpendicular lines, complementary angles, and linear pair. Vertical angles are equivalent, perpendicular lines intersect at right angles, complementary angles sum to 90 degrees, and a linear pair of angles sum to 180 degrees.

Without the actual diagram presented in your question, I can only provide some general insights into your question which is related to angles and lines. Firstly, vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Secondly, two lines are perpendicular if they intersect at a right angle(90 degrees). In terms of angles, two angles are complementary when they add up to 90 degrees. Finally, a linear pair refers to two angles that are adjacent (share a common vertex and side but have no common interior points) and whose non-common sides are opposite rays, i.e., they add up to 180 degrees.

Aiko has -$5.50 after buying the candles.

To find out how much money Aiko has after buying candles, we need to calculate the total amount spent on the candles and subtract it from the initial $20.

Aiko initially had $20. She returned 2 candles for $4.75 each, so she got back 2 x $4.75 = $9.50.

Then, she bought 3 candles for $3.50 each, which amounts to 3 x $3.50 = $10.50.

Finally, she bought 1 candle for $5.00.

The total amount spent on candles is $4.75 x 2 + $3.50 x 3 + $5.00 = $9.50 + $10.50 + $5.00 = $25.50.

To calculate how much money Aiko has left, we subtract the total spent from the initial amount: $20 - $25.50 = $-5.50.

Therefore, Aiko owes $5.50 after buying the candles.

The length of the Little Drop is unknown. However, the question defines that the Big Drop is twice the length of the Little Drop. The exact length cannot be factually stated without more information.

The question states that the Big drop is twice as long as the little drop. Let's say that the length of Little Drop is represented as 'L'. We don't know the exact length of 'L', but we can say that the length of the Big Drop is twice this, which can be represented as 2L.

Since we don't have a specific measure given for either drops, the exact length of Little Drop can't be determined from the information provided. However, whatever it is, we understand that Big Drop is twice that length.

Answer:

51 inches of rope?

Step-by-step explanation:

If 17 inches is 1/3 if what he needs, then have 3 of 17 inches of rope which is

= 17 × 3= 51.. so it will be 3/3

Answer:

51 inches

Step-by-step explanation:

Total length of the rope possessed by Todd = 17 inches.

But what he has corresponds to [tex]\[\frac{1}{3}\][/tex]  of his actual requirement.

Let his total requirement be represented by x.

Then [tex]\[\frac{1}{3} * x = 17\][/tex]

Simplifying,

[tex]\[x = 17 * 3\][/tex]

[tex]\[x = 51\][/tex]

Hence the total length of the rope required by Todd is 51 inches which is 3 times what he has currently.

Final answer:

Pedro had 1,482 hits, while Ricky had 1,204 hits. We determined these numbers by setting up a system of linear equations and solving for both players' hits using substitution.

Explanation:

To solve the problem of determining how many base hits teammates Pedro and Ricky had last season, we can set up a system of linear equations. Let's let P represent the number of hits Pedro had, and R represent the number of hits Ricky had. According to the problem, together they had 2,686 hits, so we can write the first equation as:

P + R = 2,686

The second piece of information tells us that Pedro had 278 more hits than Ricky, which gives us the second equation:

P = R + 278

We can substitute the second equation into the first equation to find the value of R:

P = (R + 278)

(R + 278) + R = 2,686

2R + 278 = 2,686

2R = 2,686 - 278

2R = 2,408

R = 1,204

Now, we know Ricky had 1,204 hits. To find out how many hits Pedro had, we substitute R's value back into the second equation:

P = 1,204 + 278

P = 1,482

So, Pedro had 1,482 hits and Ricky had 1,204 hits.

The answer is B. 21.

The sum of the angles in a triangle is 180 degrees. So, we have the following equation:

(5x+14) + 40 + x = 180

Combining like terms, we get:

6x + 54 = 180

Subtracting 54 from both sides, we get:

6x = 126

Dividing both sides by 6, we get:

x = 21

Therefore, the value of x is 21.

The width of the canyon is 315 ft.

An isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

Given that, Jim owns a restaurant on the edge of a canyon. He wants to install a cable car over the canyon. He needs to know the width of the canyon. (please refer to the figure attached)

m ∠ ABC = 180°-80°  (Linear pair)

m ∠ ABC = 100°

In Δ ABC,

∠ A + ∠ B + ∠ C = 180°  (sum of interior angles of a triangle)

∠ A = 180°-(100°+40°)

∠ A = 40°

Since, ∠ A = 40° and ∠ C = 40°

Therefore, ∠ A = ∠ C

Therefore, AB = BC (Side opposite to equal angles are equal)

That means,  Δ ABC is an isosceles triangle

∵ BC = 315 ft

∴ AB = 315 ft

AB is the width of the canyon.

Hence, The width of the canyon is 315 ft.
