Answer:
Tyler 96
Olivia 84
Step-by-step explanation:
6*16=96
6*14=84
The youngest her cousin can be is 4.
4(3)=12
12-2=10
10+4=14
1)
2x-y=16
-2y-x=-8
You need to solve on of the equations for x or y. I will solve the first equation for y.
2x-y=16
-y=-2x+16
y=+2x-16
Then you can substitute that y value for the y value in the second equation (2y-x=-8) can be written as 2(2x-16)-x=-8 since y=2x-16.
then you solve for x.
4x-32-x=-8
3x=24
x=8
therefore y=0 since 2(0)-8=-8
I will complete the second part of the question either in the comments or a new answer later when I have more time.
The zeros/roots of the functions are -2, 6, and 7.
