Add the equations.
x-y%2B0.5x%2By=7%2B5
1.5x=12
highlight%28x=8%29
Now use either equation to solve for y.
8-y=7
highlight%28y=1%29
x=8
y=1
Answer:
- the value should be twns and ones
Step-by-step explanation:
1 8=tens 8(1 ones)
The equation that best models this situation would be: y=40+30x
The answer is a because there are two same x values and two x values means it’s not a function
