The interest rate would be 7%
Answer:
1. (AB) y = 2/3x + -4
Step-by-step explanation:
Formula - y = m(x) + (y-intercept)
m = rise / run
"run = horizontal (left and right)
rise = vertical (up and down)"
the y intercept is always going to be where y is 0 at. (x, y) you will use your x to determine the intercept
So lets use your first question as an example
1. (AB) y = m(x) + (y-int)
y = m(x) + (-4)
the point goes to the right 6 points and goes up 4 points (rise / run)
y = 4/6(x) + (-4)
You can round up the fraction to 2/3
y = 2/3(x) + -4
54$, because the equation would be 7n+12 where n is 6 so 7*6 is 42 and 42+12 is 54
3x^2 - y^3 - y^3 - z = 3x^2 - 2y^3 - z = 3(3)^2 - 2(-2)^3 - (-5) = 3(9) - 2(-8) + 5 = 27 + 16 + 5 = 48
