8 + 4 = 12 that's Leslie's age in 4 years
So if she would be 12 bill will be 6 . Because 6•2=12 so Leslie is 12 bill will be 6
Answer:
Domain: {-1,-2,-3,-4}
Range: {4,5}
Step-by-step explanation:
As the range has repeated numbers, you don't have to repeat them.
A vertical line i believe since x is constant

ANSWER:
a) y = 15x + 75
b) 50 weeks
EXPLANATION:
P A R T A
2 weeks, 105 dollars --> (2, 105)
5 weeks, 150 dollars --> (5, 150)
<u />
<u>if we use slope intercept form (y=mx+b), we must:</u>
1) find the slope
y2 - y1 -->> 150 - 105 = 45
x2 - x1 -->> 5 - 2 = 3
45/3 = 15
2) find the y intercept
y = 15x + b -->> 150 = 15 (5) + b -->> 150 = 75 + b -->> 75 = b
--------------------------------------------------------------------------------------------
P A R T B
y = 15x + 75 (substitute the y with 825 because that is the goal)
825 = 15x + 75 (solve normally)
750 = 15x
50 = x
