Answer 2
Answer:

Answer: The scale factor of the dilation =3


Step-by-step explanation:

We know that if we transform point (x,y) by using dilation with scale factor k then the coordinate of the image will be (kx,ky).

Given: under a dilation, the point (2, 6) is moved to (6, 18)

Here (x,y)=(2,6) and (kx,ky)=(6,18)

\n\Rightarrow\ x=2\ and\ kx=6\n\Rightarrow\ k(2)=6\n\Rightarrow\ k=3

Hence, the scale factor for the given dilation= 3.

What expression is equivalent to -5x^(2)-10x

Answers

Good morning ☕️

Answer:

-5x(x + 2)

Step-by-step explanation:

the key is factoring:

-5x² - 10x = -5x × (x) - 5x × (2)  {here we notice that -5x is a common factor}

               = -5x(x + 2)

What is the sum of the polynomials 8x^2-7x+3 and 2x^2 +10x-5

Answers

Answer:

10x^2 + 3x - 2

Step-by-step explanation:

Final answer:

To find the sum of the polynomials, add the like terms together. The sum of the given polynomials is 10x^2 + 3x - 2.

Explanation:

To find the sum of the polynomials, you need to add the like terms together. Start by adding the coefficients of the x-squared terms, which are 8 and 2. This gives you 10x^2. Then, add the coefficients of the x-terms, which are -7 and 10. This gives you 3x. Finally, add the constant terms, which are 3 and -5. This gives you -2. So, the sum of the polynomials is 10x^2 + 3x - 2.

Fred works for $8.75 per hour. His regular hours are 40 hours per week and he gets time and a half for overtime. One week he works 47.5 hours. He wants to calculate his pay.

Answers

For the first 40 hours, he gets 8.75/hour, so 40*8.75 = 350. For the last 7.5 hours, he gets (8.75*1.5)/hour. 8.75*1.5 = 13.125/hour, or 13.13/hour. Then do 13.13/hour * 7.5 hours = 98.48. Now add together 350 and 98.48. That equals $448.48 total for the week

Answer:

350, 13.13/hour, 98.48, 448.48.

Step-by-step explanation:

It's not clear where the answer is above, so I found it and put it here.

Does the point (2,3) lie on the line y=3/4x-2

Answers

No.

If you substitute x with 2 and y with 3, it doesn't equal meaning its not a point.
