B)-3 for the vertex, do u have to graph it?
Answer:
D
Step-by-step explanation:
you have to multiply .79 to both a and 1.2. A is wrong because it's saying we need to multiply .79 to 1.2lb. which is the weight of oranges and the total cost of apples and oranges which is 6.27.
= -x^2 - (3x - 12x^2 + 7x ) - (2 - 2x - 2)
= -x^2 - 3x + 12x^2 - 7x - 2 + 2x + 2
= 11x^2 - 8x
Answer
11x^2 - 8x
Total was x
subtract 36.25 amount of money and you have -14.75 left
You can write this
x - 36.25 = -14.75
add 36.25 to both sides
x = -14.75 + 36.25
Solve by combining like terms
x = 21.5
You had $21.5 on your account before you withdrew $36.25 and had a balance of -$14.75 left.
Hope this helps!
