The ordered pair (-9, 1) is a solution to the inequality y ≤ 2x - 7

Replace x in the equation with the x value from the ordered pair and see if the y value meets the inequality.

y ≤ 2(-9) -7

y ≤ -18 - 7

y ≤ -25

The y value in the ordered pair is 1, so replace y with 1 and see if the inequality is true:

1 ≤ -25

1 is a positive value and the equation equals a negative value, so this is not true, because 1 is greater than -25.

answer: the correct one is a

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
