Answer:
You need to add the expressions. When you do I will edit my answer and give it to you.
Calculate the difference, Reduce the fraction with 2, Multiply the numbers
(-10)^2+(7/2)^2-10
To raise a fraction to a power, raise the numerator and denominator to that power
100+49/4 -10
Calculate the sum
409/4
Or
102 1/4
Or
102.25
Subtract x/a from both sides.
y/b=1-x/a
Multiply by b on both sides.
y=b(1-x/a)
If you want, you can leave it like that or you can distribute the b through.
y=b-bx/a
