Answer:
No.
Step-by-step explanation:
Use a vertical line test.
Vertical line test: If you can draw a vertical line and it does not cross two points in the line, then it is a function.
So, we draw a line.
Draw it through 9,0
It intercepts two points so No. This is not a function.
Hope this helps plz hit the crown :D

Answer:
x = 23
Step-by-step explanation:
Eliminate parentheses, separate the variables and the constants, divide by the coefficient of the variable.
7(x +4) = 9(x -2) . . . . . given
7x +28 = 9x -18 . . . . . eliminate parentheses using the distributive property
28 = 2x -18 . . . . . . . . . subtract 7x*
46 = 2x . . . . . . . . . . . . add 18
23 = x . . . . . . . . . . . . . divide by 2
The solution is x = 23.
Check
7(23+4) = 9(23-2) ⇒ 7·27 = 9·21 . . . true (=189)
__
* We choose to subtract 7x instead of 9x so that the resulting x-term has a positive coefficient.
_____
Additional comments
The properties of equality tell you that you can do anything you like to an equation, as long as you do the same thing to both sides of the equation. So, when we say "subtract 7x", we mean that value is subtracted from both sides of the equation. Subtracting a value, or adding its opposite, is a way to remove a term from a place in the equation where you don't want it.
Here, the smaller x-coefficient is on the left, so we choose that term to subtract. That leaves the remaining x-term on the right (with a positive coefficient). We don't want any constants there, so we add the opposite of that constant. (The opposite of -18 is 18, so that is what we add--to both sides.)
__
Sometimes you will be told differently. You will be told to "put that over there and change its sign" or "cross-multiply". These instructions are based on appearance. The fundamental, always-applicable rule is "do the same thing to both sides of the equation." With practice and understanding, you can begin to think in terms of these shortcut suggestions.

Step-by-step explanation:
0 x any number = 0
4(-5) = -20
126/(-18) = -7
Answer:
1. 0
2. -20
3. -7
Step-by-step explanation:
1. 0 times anything is equal to nothing times something.
So, the first one is 0.
2. For 4 x -5, you can just do 4 x 5 x -1, which equals 20 x -1, whixh equals -20.
3. Remember, a negative times a negative = a positive. So, the number must be negative. Just do 126 / 18 x -1, which equals -7.

Michael is buying a new pair of headphones from an electronics store. The headphones cost $15.50, but Michael has a coupon that will reduce the cost by $4.00. He must pay 6% sales tax on the discounted price of the headphones. How much will Michael pay in total for the headphones, including tax?
Answers
Answer: Michael pays $12.19 for the headphones including the tax.
Step-by-step explanation:
The initial price of the headphones was $15.50
When Michael uses his coupon, the price is decreased by $4, then the new price will be:
$15.50 - $4 = $11.50
Now Michael must pay 6% for taxes (on the discounted price), then he must pay:
$11.50 + (6%/100%)*$11.50
$11.50 + 0.06*$11.50
$11.50*1.06 = $12.19
Then Michael pays $12.19 for the headphones including tax.

From 20 tons to 99 tons? Increase or decrease?
Answers
Answer:
increase in weight
Step-by-step explanation:
Answer:
Increase.
Step-by-step explanation:
20 is larger than 99. if one ton is 2000 pounds then 20 tons are 40,000 pounds. So 99 times 2000 is 198,000 pounds, which is larger than 40,000.
Summary: 20 tons (40,000 pounds) < 99 tons (198,000) pounds

Jing just got a new job. She started at a pay rate of $12.50 per hour and will get a $0.50 raise each year. Max started a job where is salary is found by the equation y=x+10, where x is the number of years. What is the initial value for Jing?
Answers
Answer:
initial value for Jing is $12.50.
Step-by-step explanation:
It is given that Jing started at a pay rate of $12.50 per hour and will get $0.50 per year. So, 0.50 is slope and y intercept is 12.50 for this equation.
The y intercept represents the initial value for the Jing.
So, initial value is $12.50.
