Answer: 231,469.335
Step-by-step explanation:
Answer: y = -2x +3
slope intercept form: y = mx +b
divide everything by 6.
2x = 3 - y
isolate y by subtracting 3 from both sides
2x - 3 = -y
divide by negative 1 to get positive y
-2x +3 = y
Answer:
(1.0025ⁿ)² + 3.7124×(1.0025ⁿ) - 5.3124 = 0
Step-by-step explanation:
Nina will have saved the enough money to pay off the remaining balance on the loan when the functions are the same. So
f(x) = g(x)
86248 - 74248(1.0025)ⁿ = 20000(1.005)ⁿ - 20000
we sum 20000 on each side of the equation
106248 - 74248(1.0025)ⁿ = 20000(1.005)ⁿ
then we divide by 2000 each side of the equation
5.3124 - 3.7124(1.0025)ⁿ = 1.005ⁿ
the square root of 1.005 is aproximately 1.0025, so
1.005 ≈ 1.0025²
5.3124 - 3.7124(1.0025)ⁿ = (1.0025²)ⁿ
Since (1.0025²)ⁿ = 1.0025²ⁿ = (1.0025ⁿ)² we can write:
(1.0025ⁿ)² + 3.7124(1.0025ⁿ) - 5.3124 = 0
$7,469.25 but I’m not 100% sure if that’s correct.
4*3z-4*2 = 9z-7
12z-8 = 9z-7
12z-9z = -7+8
3z = 1
z = 1/3
