X=y-8 and -x-y=0 solve by substitution
Answer:
y=4
Step-by-step explanation:
x=y-8
-x-y=0
-(y-8)-y=0
Distribute the negative
-y+8-y=0
Combine the like terms
-2y+8=0
-8 (to both sides)
-2y=-8
Divide by -2
y=4

Triangle A is the pre-image in a translation, and triangle B is the image, as shown below.
On a coordinate plane, triangle A is shifted 6 units to the right to form triangle B.
How was triangle A translated?
four units left
four units right
six units left
six units right
Answer: D is correct
Step-by-step explanation: Got a 100% on my test
The translation of triangle A is (d) six units right
The translation from triangle A to BTranslation involves changing the position of a shape
From the question, we understand that:
Triangle A represents the pre-imageTriangle A is shifted to the right by 6 unitsThis means that, triangle A was translated by 6 units to the right
Hence, the true statement is (d)

Answer:
[tex]2 {x}^{3} + 11{x}^{2} - 25x - 28[/tex]
Step-by-step explanation:
Using foil method, Multiply the first term
[tex]2 {x}^{2} \times x = 2 {x}^{3} [/tex]
Next, Multiply the Outer term in each parenthesis. (2x^2 and 7

Complete the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50¢ price increases.
b(x) = -____x2 + ____x + _____
Answer:
b(x) = -2x² + 7x + 114
Step-by-step explanation:
Step-by-step explanation:
First we convert 50 cent into dollar,
1 cent = dollar
1 cent = 0.01 dollar
50 cent = 0.5 dollar
According to question,
x is the number of 50¢=$0.5 price increases.
b(x) is the revenue generated
He currently charges $3 per book.
i.e. price of book = 3+0.5x
Quantity or average = 38 per day

The measure of an exterior angle of a triangle is x. The measure of the adjacent interior angle is at least twice x. List three possible solutions for x.
Answer:
x=exterior
y=interior
x+y=180
y is greater than or = to 2x.
So one value could be x+2x=180
3x=180
x=60
or you could do 2x+1+x=180
3x=179
x=179/3
or 2x+2+x=180
3x=178
x=178/3

C (-1, 0)
Step-by-step explanation:
(x,y) -> (x - 8, y - 2)
A (2, 3) -> (2 - 8, 3 - 2) = A (-6, 1)
B (6, 6) -> (6 - 8, 6 - 2) = B (-2, 4)

In a sale normall prices are reduced by 10% Natalie brought a pair of shoes from the sale and they cost £54 what was the original price
Answer: £60
Step-by-step explanation:
Natalie bought a pair of shoes for £54 which had been reduced by 10%.
To find the original cost, assume the original cost is x.
The discount would be: 10% * x
The expression would therefore be:
x - (10% * x) = 54
x - 0.1x = 54
0.9x = 54
x = 54 / 0.9
x = £60

Answer:
x = -55
Step-by-step explanation:
7 + x/5 = -4
Combine the constants.
x/5 = -11
Multiply both sides by 5 to simplify the denominator.
x = -55
Check.
7 + (-55)/5 = -4
7 + (-11) = -4
7 - 11 = -4
-4 = -4
Your answer is correct.
