Given that the equation y=mx + b where m is 12 and the line passes through the point (-2,8), what would be the value of b?
larisa86 [58]

Answer:

d

Step-by-step explanation:

The answer would be D. We can continue the line from the point (-2,8) because we know the slope so we will continue it forward by two on the x axis. Since we go forward by two we are going up by 24 (12*2) on the y axis so the y intercept (b) would be 8 + 24 which is 32. Sorry if it is hard to understand.

Solve for p. 2(p + 1) = 16 What is the answer?
Mashutka [201]

Divide both sides by 2

p + 1 = 16/2

Simplify 16/2 to 8

p + 1 = 8

Subtract 1 from both sides

p = 8 - 1

Simplify 8 - 1 to 7

<u>p = 7</u>

Gekata [30.6K]

Answer:

69,286,455 cu inches

Step-by-step explanation:

<u>Step 1: Convert yards to inches</u>

1 cu yard = 46656 cu inches

11 cu yard = y cu inches

<em>Cross multiply</em>

y = 11 x 46656

y = 513216 cu inches

<u>Step 2: Find total inches</u>

513216 + 17 = 513233 cu inches

<u>Step 3: Multiply total inches by 135</u>

513233 x 135 = 69,286,455 cu inches
