Substitute z with 3.
3(4)^3
Cube 4 with 3
3(64)
Multiply 3 and 64

T = state income return (without sales tax)
106% of t = 4960.80
AKA
1.06t = 4960.80 --> Divide both sides by 1.06 to find the state income return without sales tax
t = 4680
Subtract t from the state income return with sales tax.
4960.80 - 4680 = 160.80
<u>She paid $160.80 in sales tax.</u>

x = 4.1925
or x = -1.1925
a=1
b=-3
c=-5
Answer:
y = x + 2.5
Step-by-step explanation:
slope = (y2-y1)/(x2-x1) where the variables indicate the coordinates of the two points
slope = (2.5-1.5)/(0+1) = 1
equation = y-y1 = m(x-x1)
y - 2.5 = x
y = x + 2.5
