Remember to include the positive and negative roots


(7x-2)^2=256
sqrt both sides
7x-2=+/-16
add 2 to both sides
7x=2+/-16
divdide both sides by 7
x=(2+/-16)/7)

x=(2+16)/7=18/7=2 and 4/7
x=(2-16)/7=-14/7=-2

x=2 and 4/7 or -2

What would a monthly payment be on a purchase of a $10,000 car at a 5.9% for 4 years?
gizmo_the_mogwai [7]
The current monthly pay can be calculated as follows;
A=p(1/r/100)^n
A=10000
r=5.9/12=0.5%
10000=p(1+0.5/100)^(4*12)
10000=p(1.005)^48
p=10000/(1.005)^48
p=7,871
the monthly payment will be:
7871/12
=$655.92

Slope and y intercept y=7/4x-10
Andreas93 [3]

Hi there!

The slope is the number in front of x so it is 7/4 or 1 3/4

The y-intercept is the independent number in the equation, so it is -10
