The numbers will be X and Y with X being the lesser
x+y=45
2y=5x+6
now use a subtraction method to solve
x+y=45
y=45-x
2 (45-x)=5x+6
90-2x=5x+6
-7×=-84
x=12
y=45-12
y=33
so, x=12 and y=33
Decimal form: 4.05, 0.5
Exact form: 9/2, 1/2
Answer: If I remember correctly, the answer should be <em>y=-2(3)^x. </em>
The x intercept is not 10!
f(x)=0.75x-7
x= 7/0.75 ≠ 10
so last one is false!
(for finding x intercept make the y/f(x) value 0)
