A=2b^3-1 what's the value of b if a is 13

skelet666 [1.2K]

$\sf~A=2b^3-1$

Plug in A = 13

$\sf~13=2b^3-1$

Add 1 to both sides:

$\sf~14=2b^3$

Divide 2 to both sides:

$\sf~7=b^3$

Find the cube root of both sides:

$\sf~b=\sqrt[3]{7}$

$\sf~b\approx~1.91$

lesya [120]

Answer: The slope is 2/3, y=2/3x+1

Step-by-step explanation: The 2 points, (3,3) and (6,5), use the method y2-y/x2-x1. Then you find the slope that way, then use point slope form for the slope intercept form: y-y1=m(x-x1), then substitute and solve to get y=2/3x+1
