What is the equation of the line perpendicular to –x + y = 7 and passing through (-1, -1)?

1 answer:

6 0

- x + y = 7
y = x + 7
slope = 1
perpendicular slope = -1

at point (-1, -1),
y = mx + c
-1 = -1 (-1) + c
-1 = 1 + c
c = -1 -1
c = - 2

equation:
y = -x -2
y + x = -2 or - x - y = 2

Find the Volume. 4 2/3 2cm 9 1/8

Novay_Z [31]

Answer:

$85 cm^{3}$

Step-by-step explanation:

The formula to find the volume of a rectangular prism such as this is :

V = length * width * depth

To solve for this problem, we just plug in the values and multiply it all out.

$9\frac{1}{8} *2*4\frac{2}{3}$ = $85\frac{1}{6}$

Therefore, the volume of this prism is 85 $cm^{3}$ .
