Answer:
y = 25 + 40x
Step-by-step explanation:
Let
y = the total amount of money Justin has
x = number of weeks
Amount Justin has in the bank = $25
Amount Justin earns per week = $40
Equation for how much money Justin has (including the amount he has in the bank) in x weeks
the total amount of money Justin has = Amount Justin has in the bank + (Amount Justin earns per week * number of weeks)
y = 25 + (40 * x)
y = 25 + 40x
The equation is
y = 25 + 40x
Answer:
WHAT
Step-by-step explanation:
We factor the denominators
Factor x^2 - 16
x^2 - 4^2
We use a^2 - b^2 = (a+b)(a-b)
so x^2 - 4^2 = (x+4)(x-4)
Replace it in the given equation
Excluded values are the values that makes the denominator 0
we have (x-4) and (x+4) in the denominator
We set the denominator =0 and solve for x
x-4 =0
Add 4 on both sides
x= 4
x+4=0
subtract 4 onboth side
so x= -4
Excluded values are x=-4 and x=4
