U have to get the common denominator and do to the top what u do to the bottom #1 is 4/5 if u simplify
Answer:
A. $6.67
Step-by-step explanation:
a) 2y -3x + 8
a) y = - 3/2x + 8/2
a) y = - 3/2x + 4
b) 5y - 15x = -30
b) 5y = 15x - 30
b) y = 15/5x - 30/5
b) y = 3x - 6
3x - 6 = 3/2x + 4
3x -3/2x = 4+6
3/2x = 10
x = (10) / (3/2) = $6.67
F(x)=5x+10
5x=-10
x=-10/5
x=-2
Result is f(-2).
