Answer:
Inverse of

Step-by-step explanation:
Let y = -5x-4
Swap y and x
x = -5y -4
Solve for y
x+4 = -5y
which is the inverse
The frequency distribution chart of the math quiz has a data that is skewed left.
<h3>How to interpret the shape of the histogram?</h3>
From the complete question (see attachment for histogram), we have the following highlight:
The dataset on the right-hand side is taller than those on the left.
This means that the dataset is skewed left.
Hence, the statement that best describes the data is (a) The data is skewed left.

Answer:
x+y=-5.75
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, you would simply need to use the distributive property!
-(2)x-(2)2+(2)y-(2)9=1
-2x-4+2y-18=1
Then you need to add/subtract so the similar numbers are together.
-2x+2y-22=1
-2x+2y=23
x+2y=-11.5
x+y=-5.75

Pick any number. Multiply the 7 and the 11 both by it,
and you'll have an equivalent ratio.
Examples:
(by 2) . . . 14 to 22
(by 6) . . . 42 to 66
(by 10). . . 70 to 110
(by a million) . . . 7 million to 11 million
Answer:
cost to make paper signs = $1
cost to make laminated signs = $2
Step-by-step explanation:
Let
x = cost to make paper signs
y = cost to make laminated signs
8x + 2y = 12 (1)
10x + 10y = 30 (2)
Multiply (1) by 5
40x + 10y = 60 (3)
10x + 10y = 30 (2)
Subtract (2) from (3) to solve for x
40x - 10x = 60 - 30
30x = 30
x = 30/30
x = $1
Substitute x = 1 into (1)
8x + 2y = 12
8(1) + 2y = 12
8 + 2y = 12
2y = 12 - 8
2y = 4
y = 4/2
y = $2
cost to make paper signs = $1
cost to make laminated signs = $2
