Answer:
See description below.
Step-by-step explanation:
To choose the correct equation, find the slope of the line on the graph. Identify two points on the line. Then subtract to find their rate of change using the slope formula.
When you know the slope, find the negative reciprocal. For example, if the slope is 2/1 then the negative reciprocal is -1/2. This is the slope of a perpendicular line to a line with slope 2. Choose the equation which has this same slope.
Example:
y = 2x -1
y= -1/2 +5
B)1,131.20 would be the answer. 1010x0.14=141.4x8=B
2 and 3
negative numbers won't work, nor will 0
1 and 2 won't work because 1*8=2*4
2 and 3 is the answer
Answer:
V = 48 cubic units
Step-by-step explanation:
Use this equation to find the volume
Simplify the exponent
Multiply
V = 48 cubic units

z^2 - z - 72
z^2 - 9z + 8z - 72
<u>Step 1</u>: 72 = 9 * 8 and when we subtract -9+8 = -1 and that's how I went from z^2 - z - 72 to z^2 - 9z + 8z - 72.
<u>Step 2</u>: Taking out common value from first and second; and third and fourth.
z^2 - 9z = z(z - 9)
8z - 72 = 8 (z - 9)
z^2 - 9x + 8x - 72
z(z-9) + 8(z-9)
(z-9) (z+8)
