Step-by-step explanation:
15 - 2(7 - x) = 7
collect like terms
-2(7 - x) = 7 - 15
-2(7 - x) = -8
divide both sides by -2
7 - x = -8/-2
7 - x = 4
collect like terns
-x = 4 - 7
-x = -3
dividing both sides by -
x = 3

y=-1/2x(x-8)
Show steps to put in vertex form
Answer:
y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0
Step-by-step explanation:
y = -1/2x(x-8) (distributive property of equality)
y = -1/2x^2 + 4x + 0
Vertex form : y = ax2 + bx + c
There is no C so you can also represent that by putting a zero so,
y = -1/2x^2 +4x + 0,
Which is the same as,
y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0

The evaluated value of the given function is -
│-9│+ │11│ - │-15│ + │-6│= 11.
What is function? What is modulus function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
We can define the modulus function as -
|x| = - x {x < 0}
|x| = x {x > 0}
Given is to evaluate the expression -
│-9│+ │11│ - │-15│ + │-6│
We can evaluate the function as -
│-9│+ │11│ - │-15│ + │-6│
9 + 11 - 15 + 6
20 - 9
11
So, we can write -
│-9│+ │11│ - │-15│ + │-6│= 11
Therefore, the evaluated value of the given function is -
│-9│+ │11│ - │-15│ + │-6│= 11.

When multiplying a whole number by a positive fraction smaller than 1, the answer is always smaller than the original number.
Examples:
5 · [tex]\frac{1}{2}[/tex] = 2 [tex]\frac{1}{2}[/tex] or 2.5
6 · [tex]\frac{3}{4}[/tex] = 4 [tex]\frac{1}{2}[/tex] or 4.5
14 · [tex]\frac{1}{3}[/tex] = 4 [tex]\frac{2}{3}[/tex]
When dividing a whole number by a positive fraction smaller than 1, the answer is always bigger than the original number.

Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher? Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher?
Answer:
2.125 liters of juice
Step-by-step explanation:
Total liters of juice = 9
Total liters left = 0.5
Total liters used = Total liters of juice - Total liters left
= 9 - 0.5
= 8.5
Total liters used = 8.5 liters
He pours equal amounts of the juice into 4 pitcher
Liters per pitcher = Total liters used / number of pitchers
= 8.5 / 4
= 2.125 liters
Liters per pitcher = 2.125 liters
Each pitcher has 2.125 liters of juice

Divide using synthetic division, and write a summary statement in fraction form
2x^3+3x^2+4x-10/x + 1
Using synthetic division, a summary statement in fraction form of the polynomial division is; 2x² + x + 3 - (13/(x + 1))
How to use Synthetic Division?
We are given the polynomial fraction as;
(2x³ + 3x² + 4x - 10)/(x + 1)
This means that we want to divide the polynomial (2x³ + 3x² + 4x - 10) by (x + 1) using synthetic division.
For the divisor, we have x + 1, and that means x + 1 = 0, x = -1
So, we'll be using -1 for the synthetic division and we have;
-1 | 2 3 4 -10
× -2 -1 -3
-------------------------
2 1 3 -13
Now we will form the expression in the form of fraction again
2x² + 1.(x) + 3 - 13/(x + 1)

BE||CD. Find the value of x and AC.
Answer:
x = 4.8
AC = 16.8
Step-by-step explanation:
From the picture attached,
In ΔABE and ΔACD
BE║CD, and the AC and AD are the transversal lines.
∠ABE ≅ ∠ACD [Corresponding angles]
∠AEB ≅ ∠ADC [Corresponding angles]
ΔABE ~ ΔACD [By AA property of similarity of two triangles]
And by the property of similar triangles, corresponding sides of the similar triangles are always proportional.
[tex]\frac{\text{AC}}{\text{AB}}=\frac{\text{AD}}{\text{AE}}[/tex]
[tex]\frac{x+12}{12}=\frac{10+4}{10}[/tex]
[tex]\frac{x+12}{12}=\frac{14}{10}[/tex]
10(x + 12) = 12 × 14
10x + 120 = 168
10x = 168 - 120
x = 4.8
AC = x + 4.8
= 12 + 4.8
= 16.8
