Answer: --42
Step-by-step explanation:
All that you have to do in this equation is substitute the value of x given with the x's in the expression. SO...
Expression: -4(5x+2) - 6(x-3)
Substitute: -4(5(2)+2) - 6((2)-3)
Solve: -4(10+2) - 6(-1)
-4(12) - 6(-1)
-48 +6
Answer: -42
Hope this helps!
Answer:
y ≥ 6.25
Step-by-step explanation:
f(x)=4x²+2x-6
positive (4) leading coefficient, curve is left up and right up
x coordinate of vertex: x = - b/2a = - 2/2*4 = - 1/4 (-0.25)
y = 4*(-1/4)² + 2*(-1/4) - 6 = -6 1/4 (-6.25) ... extreme
range: y ≥ - 6.25 [-6.25,∞)
