Answer:
a. y = 4x b. 48 feet
Step-by-step explanation:
y = mx + b
Plotted points found:
(5,20) (10,40)
Delta y/Delta x
(40-20)/(10-5)
20/5 = 4
Slope: 4
y = 4x + b
The y-intercept is when x = 0. In this case, the y-intercept is 0.
Equation: y = 4x
b.
y = 4(12)
y = 48 feet
First, solve the exponent part because it has a higher precedence than multiplication. And we have a negative exponent. Which means we takes the reciprocal of 4 then take to the power of 4.
4^-4 = 1/4^4 = 1/256
Now do the multiplication part.
16 * 1/256 = 1/16
