Answer:

Area 2 = 72 cm²
CD = 7 cm

Step-by-step explanation:

For similar figures, side lengths (and any other linear measure) are proportional. Areas are proportional to the square of the scale factor for side lengths.

Perimeter 1/Perimeter 2 = CD/EF

21/18 = CD/6

CD = 6(21/18)

CD = 7 . . . cm

Area 2/Area 1 = (Perimeter 2/Perimeter 1)²

Area 2/98 = (18/21)²

Area 2 = 98(6/7)²

Area 2 = 72 . . . cm²

Answer:

D. y = 2x + 3

Step-by-step explanation:

Use the table to answer the question.

x:-2 -1 0 1 2

y: -1 1 3 5 7

Which equation represents the relationship between x and y shown in the table.

Solution:

The table shows a linear relationship between x and y.

A linear equation is in the form y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change (slope) and b is the value of y when x = 0.

The table (x, y) has the points (-2, -1) and (0, 3). The equation is given by:

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-(-1)= \frac{3-(-1)}{0-(-2)} (x-(-2))\\\\y+1=2(x+2)\\\\y+1=2x+4\\\\y=2x+3$
