Answer:

14

Step-by-step explanation:

Simplify the following:

5 - 2×9 + 9^2/3

Hint: | Evaluate 9^2.

9^2 = 81:

5 - 2×9 + 81/3

Hint: | Reduce 81/3 to lowest terms. Start by finding the GCD of 81 and 3.

The gcd of 81 and 3 is 3, so 81/3 = (3×27)/(3×1) = 3/3×27 = 27:

5 - 2×9 + 27

Hint: | Multiply -2 and 9 together.

-2×9 = -18:

5 + -18 + 27

Hint: | Evaluate 5 + 27 using long addition.

The table represents a linear function. <br><br> What is the slope of the function?
otez555 [7]

Answer:

-6

Step-by-step explanation:

The slope of a line is given with the formula

m=\frac{y_2-y_1}{x_2-x_1}

Using the first two points, (-2, 8) and (-1, 2), we have

m = (2-8)/(-1--2) = -6/(-1+2) = -6/1 = -6

1. The rectangle shown is dilated by a scale factor of 2.
stealth61 [152]
Well, I don't what your question is, but I will assume that you want the dimensions of the rectangle after its dilation. So, multiply the dimensions of the rectangle by 2 to make it dilated.
