Answer:
y=6x+5
Step-by-step explanation:
Answer:
I'll setup the problem and you can do the calculations
Step-by-step explanation:
The formula for simple interest:
I = P*r*t
I = interest
P = principle or amount invested
r = interest rate per period (period is a year)
t = number of periods
P = 4920
r = .13
t = 8

Answer:
y =
x + 30
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = (0, 30) and (x₂, y₂ ) = (70, 40) ← 2 points on the line
m =
=
= ![\frac{1}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D)
The line crosses the y- axis at (0, 30) ⇒ c = 30
y =
x + 30 ← equation of line
Answer:
16
Step-by-step explanation:
calculator..........
3x2=6/2=3x2=6
3x2=6x2=12
4x2=8x2=16
3x4=12
2.5x4=10x2=20
The answer is 12+12+16+6+20=66
