Answer:
- 2
Step-by-step explanation:
The composition of inverse functions gives x
g(x) and
(x) are inverse functions, then
(g(x)) = x , thus
(g(- 2)) = - 2
Set up your two equations:
<span>9x+7y=53 </span>
<span>3x+5y=25 </span>
<span>X=cost per pound of jelly bean </span>
<span>Y=cost per pound of trail mix </span>
<span>Multiply the second equation by (-3): </span>
<span>-9x-15y=-75 </span>
<span>+ 9x+7y=53 <---- copy first equation and add them </span>
<span>—————— </span>
<span>0x-8y=-22 </span>
<span>Then solve for y: </span>
<span>Y=2.76 this is your cost per pound of trail mix. </span>
<span>Then plug y back in to one of the original equations and solve for x: </span>
<span>3x+7(2.75)=25 </span>
<span>X=3.75 this is you cost per pound of jelly beans</span>
I think there is a 25% chance to a 37% chance you'll get an orange hat
Answer:
x + y = 11
10x + 5y = 80
