f(x) = 8x^2 + 8x - 12 in vertex form
Answer:
f(x) = (x + 4)² - 4
Step-by-step explanation:
Write the equation f(x) = x² + 8x + 12 in vertex form by completing the square:
f(x) = (x² + 8x + (8/2)²) + 12 - (8/2)²
Simplify:
f(x) = (x² + 8x + 16) + 12 - 16
Subtract to find the 'k' value:
f(x) = (x + 4)² - 4. This is the equation in vertex form.
Answer:
y=8x2+8x−12
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex (h,k).

Step-by-step explanation:
Lauren is making candy bags for halloween. She has 24 lollipops, 12 candy bars, and 42 pieces of gum. She wants each bag to have the same number of each kind of candy. What is the greatest number if bags she can make if all the candy is being used? How many pieces of each candy will be in each bag.
Answer:
a) 6 bags
b)
4 lollipops per bag
2 candy bars per bag
7 pieces of gum per bag
Step-by-step explanation:
She wants each bag to have the same number of each kind of candy.
a) What is the greatest number if bags she can make if all the candy is being used?
We solve the above question using Greatest Common Factor method
The first step would be to find the factors of 12, 24 and 42
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42
Then the greatest common factor is 6.
Therefore, the greatest number of bags she can make if all the candy is being used is 6 bags.
b) How many pieces of each candy will be in each bag.
We are told that:
She has 24 lollipops, 12 candy bars, and 42 pieces of gum.
Hence,
For Lollipops = 24 lollipops ÷ 6 bags = 4 lollipops per bag
For Candy bars = 12 candy bars ÷ 6 bags = 2 candy bars per bag
For gum = 42 pieces of gum ÷ 6 bags =
7 pieces of gum per bag

Answer:
[tex]\boxed {z = 42}[/tex]
Step-by-step explanation:
Solve for the value of [tex]z[/tex]:
[tex]-7 = \frac{z}{-6}[/tex]
-Multiply both sides by [tex]-6[/tex]:
[tex]-7(-6) = z[/tex]
[tex]42 = z[/tex]
-Switch sides:
[tex]\boxed {z = 42}[/tex]
Therefore, the value of [tex]z[/tex] is [tex]42[/tex].

a school has 294 chairs.there are 14 chairs at each table. two chairs will be removed from each table.how many chairs will be left in the cafeteria?
Answer:
252
Step-by-step explanation:
because there are 14 chairs at each table => there are: 294/14= 21 (tables)
two chairs will be removed from each table => the number of chairs removed are: 21.2 = 42 (chairs)
the chairs will be left in the cafeteria are: 294 - 42 = 252( chairs)
When two chairs will be removed from each table, then there would be 252 chairs left in the cafeteria.
The dividend divisor quotient remainder formula:Dividend = Divisor × Quotient + Remainder.
For given question,
total number of chairs = 294
there are 14 chairs at each table.
So, to find the number of tables in the cafeteria we need to divide total number chairs by 14.
The number of table would be,
= 294/14
= 21
This means, there are 21 tables.
If we remove two chairs from each table, then number of chairs at each table would be 14 - 2 = 12
So, the total number of chairs left in the cafeteria would be,
= 21 × 12
= 252
Hence, there will be 252 chairs left in the cafeteria.

if the measure of angle 1 is 57°, find the measures of angle 6
Answer:
123
Step-by-step explanation:
180 - 57 = 123
supplementary
Answer:
∠6 = 123°
Step-by-step explanation:
∠1 = ∠4 because they are vertically opposite angles and vertically opposite angles are equal.
∠4 + ∠6 = 180 (same side interior angles are equal)
∠6 = 180 - 57
∠6 = 123°
How many ways can six slices of pepperoni pizza and three slices of cheese pizza be divided among five students if one of the students is a vegetarian?
Answer: Vegan student gets 9/5 cheese slices
The rest of the 4 students get each: 5/5 slices of pepperoni + 1/2 slice of Pepperoni + 3/10 slice of cheese.
Step-by-step explanation:
6 slices of Pepperoni + 3 slices of cheese = 9 slices total. We need to divide the slices among 5 students, 1 is vegan.
9 divided by 5 = 1 and 4/5 slices or 9/5 slices.
The 9 slices make 45/5 slices.
3 slices of cheese = 15/5 slices.
6 slices of pepperoni = 30/5 slices.
Vegan student gets 9/5 cheese slices. Leaving 6/5 slices or 12/10 slices of cheese, 12/10 divided by 4=3/10
The rest of the 4 students get each: 5/5 slices of pepperoni + 1/2 slice of Pepperoni + 3/10 slice of cheese.
5/5=10/10, 1/2=5/10, 3/10
10/10 + 5/10 + 3/10 = 18/10=9/5 slices each person.
Select the correct answer. Solve the equation for x in terms of c. 2/3(cx + 1/2) - 1/4 = 5/2
Answer:
x = 29/8c
Step-by-step explanation:
2/3(cx+1/2) - 1/4+ 1/4 = 5/2+1/4
2/3(cx+1/2) = 11/4
1/3(cx+1/2) = 11/4 / 2
cx/3 + 1/2/3 = 11/4/2
cx/3 + 1/2*3 = 11/4/2
cx/3 + 1/6 = 11/4/2
cx/3 + 1/6 = 11/4*2
cx/3 + 1/6 = 11/8
cx/3 = 11/8 - 1/6
cx/3 = 29/24
cx = 29/24 * 3
x = 29/8 / c
x = 29/8c
