Answer:

y - 6 = -7(x + 8)

Step-by-step explanation:

Slope: m = (y2-y1)/(x2-x1) = (6 - -1)/(-8 - -7) = (6 + 1)/(-8 + 7) = 7/-1 = -7

Point-slope form: y - 6 = -7(x - -8)

=> y - 6 = -7(x + 8)

Find the value of z. round to the nearest hundredth

Svetradugi [14.3K]

ANSWER

C. 64.29

EXPLANATION

The bigger right triangle is similar to the smaller right triangle, therefore

$\frac{30}{14} = \frac{z}{30}$

Multiply both sides by 30;

$30 \times \frac{30}{14} = \frac{z}{30} \times 30$

Simplify

$z = \frac{900}{14}$

$z = 64.28571429$

We correct to the nearest hundredthth to obtain,

$z = 64.29$

The correct choice is C.
