f(x)=2x^2+6x-4

Find the f(-5) by substituting x = -5 in the equation.

f(-5)=2(-5)^2+6(-5)-4\\f(-5)=2(25)-30-4\\f(-5)=50-34\\f(-5)=16

Therefore, the answer is f(-5) = 16.

-3c=15 c = __ help plz
LuckyWell [14K]
You would divide negative 3 (-3) from both sides to keep the c by itself. When you divide a positive by a negative it becomes negative.

Dividing 15 by -3 would equal -5, so c = -5
