Which set of ordered pairs represents a function?
O {(-4,9), (-4,7), (1, -5), (7, -8)}
{(-5, -5), (-9,1), (8,-6), (-9,-4)}
{(-6, -6), (-2,-2), (7,-6),(-5,0)}
{(-7, -9), (-7, -7), (3,-7), (5,-5)}
Submit Answer
Answer: {(-6, -6), (-2,-2), (7,-6),(-5,0)}
Step-by-step explanation:
To find the ordered pairs that represent a function, we want to find one that doesn't have multiple outputs for one input.
{(-6, -6), (-2,-2), (7,-6),(-5,0)} is the correct answer because all the x are different, and have only one output.

Ben buys bottles of sports drinks from the store for $2 each and takes them to his school's football games. He sells
them to the crowd for $5 each.
How many bottles
does he need to sell to make a profit of $75?
Answer:
15
Step-by-step explanation
We divide the amount he's selling them for, by the amount of money he needs to make.
75 divided by 5 equals 15.
He needs to sell 15 sports drinks to make $75.
Answer:
25
Step-by-step explanation:
75:(5-2)=25
and to check it
2×25=50
25×5=125
profit = 125-50
profit=75
answer is 25
Aaliyah bought 23 chicken wings for $39.10. If Aaliyah spent $32.30, how many chicken wings did she buy?
Answer:
She bought 19 chicken wings
Step-by-step explanation:
first, find how much 1 chicken wings cost
$39.1 / 23= $1.70 (1 chicken wings cost = $1.70)
32.30/ 1.70 = 19
She bought 19 chicken wings
Hope it helps
If my answer helps you, please give me a brainliest! thanks.
If Aaliyah spent $32.30, she brought 19 chicken wings.
What is division in mathematics?One of the four fundamental operations in mathematics is division, along with addition, subtraction, and multiplication. The splitting of a large group into smaller groups so that each group contains an equal number of items is a straightforward definition of division. It is a mathematical process used for equitable grouping and distribution.
Aaliyah bought 23 chicken wings for $39.10.
Hence, as the price of each chicken wings is same, the price of each chicken wings will be= $39.10÷23 = $ 1.70
She spent $32.30 in buying chicken wings.
So, The number of chicken wings, she got = $32.30/$1.70 = 19.
Hence, if Aaliyah spent $32.30, she brought 19 chicken wings.

1- Find the slope of the line: y = -4/3 X-1*
m= -1 m= -4 m= -4/3 m= 4 v
Slope-intercept form: y = mx + b
m = the slope
y = the y-intercept
In our problem,
y = -4/3x - 1
m = -4/3
The slope is -4/3
A rectangular pan has a length that is the width. The total area of the pan is 432 in.2. What is the width of the cake pan? A = lw 10.4 in. 13.9 in. 18 in. 24 in.
Answer:
Let width = w
length = 4w/3
Area = 432 = length*width = w*4w/3
4w^2/3 = 432
w^2 = 432*3/4 = 324
w = 18
so the width of the cake pan is 18 inches.
The width of the rectangular pan is 18 inches and this can be determined by using the formula of the area of the rectangle.
Given :
A rectangular pan has a length that is 4/3 the width.
The total area of the pan is 432 square inches.
The following steps can be used in order to determine the width of the cake pan:
Step 1 - The formula of the area of the rectangle can be used in order to determine the width of the cake pan.
Step 2 - The area of a rectangle is given below:
[tex]\rm A = LW[/tex]
where L is the length and W is the width of the rectangle.
Step 3 - According to the given data, the length is 4/3 the width.
Step 4 - Substitute the values of the known terms in the above expression.
[tex]\rm 432 = w\times \dfrac{4w}{3}[/tex]
Step 5 - Simplify the above expression.
[tex]\rm 432 = \dfrac{4w^2}{3}[/tex]
[tex]\rm w^2 = 324[/tex]
w = 18 inches

5) through: (-3, 3), slope = 0
Answer:
3
Step-by-step explanation:
We know that -3 is on the x axis and 3 is on the y axis.
and the y axis usually determines if you are going to have a positive slope or negative since it would either rise or decrease. In this cause (-3, 3) shows that 3 is going to be our slope.
Answer:
y=3
Step-by-step explanation:
In a normal equation, y=mx+b, m=slope. If slope=0 in this equation, then it is safe to say that the equation is y=b. Since the Y coordinate is 3, then we can safely assume that the equation is equal to y=3

1/2z + 5 = 11 What is Z?
1/2 is a fraction.
Answer:
12
Step-by-step explanation:
Subtract 5 from both sides to get the equation
1/2z=6
Then, multiply both sides by two.
z=12
Z equals 12 because when you split it in half you will get 6 as the whole number. and 6 plus 5 = 11
Himari is solving the equation 4(−12)=16 4 x -12 = 16 . Her first step is 4−12=16 4 x - 12 = 16 .
Answer:
Step-by-step explanation:
4(−12)=16
4 x -12 = 16
Himari's solution is incorect.
it should be like shown below.
4 - (−12 ) = 16
4 + 12 = 16
16 = 16
