Well..They gave you the hint all you have to do is apply the formula
hint: the way a quadratic formula is written is [tex]ax^2 + bx + c[/tex]
So lets do this
axis of symmetry = [tex]\frac{-b}{2a} = \frac{-(-12)}{2(-3)} = \frac{12}{-6} = -2 = x[/tex]

how to find 62%of $400
Answers
Answer:
248
Step-by-step explanation:
Solution for What is 400 percent of 62:
400 percent *62 =
(400:100)*62 =
(400*62):100 =
24800:100 = 248
Now we have: 400 percent of 62 = 248
Question: What is 400 percent of 62?
Percentage solution with steps:
Step 1: Our output value is 62.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$62=100\%.
Step 4: Similarly, x=400\%.
Step 5: This results in a pair of simple equations:
62=100\%(1).
x=400\%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
\frac{62}{x}=\frac{100\%}{400\%}
Step 7: Again, the reciprocal of both sides gives
\frac{x}{62}=\frac{400}{100}
\Rightarrow x=248
Therefore, 400 of 62 is 248
Answer:
248
Step-by-step explanation:
[tex]\frac{y}{400}: \frac{62}{100}[/tex]
y · 100 = 62 · 400
100y = 24800
100y ÷ 100 = 24800 ÷ 100
y = 248

6x-8=2x-32 step by step plz
Answers
Answer:
Step 1: Add 8 to each side. 6x = 2x - 24
Step 2: Add 2x to each side. 8x = -24
Step 3: Divide each side by 8. x = -3
Answer is -3 :)
Step-by-step explanation:
Answer:
x = - 6Step-by-step explanation:
6x - 8 = 2x - 32
Move 2x to the left hand side of the equation
6x - 2x - 8 = - 32
4x - 8 = - 32
Move -8 to the right side of the equation
4x = - 32 + 8
4x = - 24
Divide both sides by 4
[tex] \frac{4x}{4} = - \frac{24}{4} \\ [/tex]

A 24-ounce can of mixed nuts contains 50% peanuts, 0.20 almonds, 1/10 cashews, and 0.20 hazelnuts. Which of the following represents the total amount of almonds and hazelnuts in the can?
Answers
Answer:
9.6 ounces
Step-by-step explanation:
Step 1
We find the amount of ounces of Almonds
Total amount of nuts in the container = 24 ounces
0.20 of the nuts are almonds.
Hence,
The amount of almonds = 0.20 × 24 ounces
= 4.8 ounces
Step 2
We find the amount of ounces of hazelnuts
Total amount of nuts in the container = 24 ounces
0.20 of the nuts are hazelnuts.
Hence,
The amount of hazelnuts = 0.20 × 24 ounces
= 4.8 ounces
Step 3
Therefore, the total amount of almonds and hazelnuts in the can is
4.8 ounces + 4.8 ounces
= 9.6 ounces
