Hi, I am on it! I will give you the answer shortly.
Answer:
6.5%; $22.10
step 1. subtract
$3.90-$60.00
step 2.
divide
$3.90÷ by the answer you get in step 1
step 3.
Convert answer into percentage by multiplying by 100
2x + 40 = 60 (Subtract 40 from both sides)
- 40 - 40
--------------------------------
2x = 20 (Divide both sides)
2x/2 = 20/2
x = 10 (This is your final answer)
4f-5=7h+g
add 5
4f= 7h + g + 5
divide by 4 to get f by its self
f = 1/4g + 7/4h + 5/4
Answer:
x = -2
Step-by-step explanation:
f(x) = 2( x^2 +9x -5x - 45)
f(x) = 2(x^2 + 4x - 45)
f(x) = 2x^2 +8x -90
axis of symmetry formula: x = -b / 2a
x = -(8) / 2(2)
x = -8 / 4
x = -2
*you can also graph the equation on a graphing calculator and find the middle of the parabola
