Answer: B
(Use the distributive property on each side of the equation.)
Step-by-step explanation:
In each of the four relations below, the x values represent inputs and the y values represent the corresponding outputs. Which relation does not represent a function? * A) { (-2, -3), (1, 3), (3, -3), (5, 3) } B) { (-1, -5), (2, 4), (3, 7), (4, 10) } C) { (-2, 3), (1, 3), (3, 3), (5, 3) } D) { (3, 4), (4, 5), (3, -4), (4, -5) }
Given:
In each of the four relations below, the x values represent inputs and the y values represent the corresponding outputs.
To find:
The relation which does not represent a function.
Solution:
A relation is a function if there exist a unique output for each input.
In options A, B and C, we get unique output for each input.
In option D, we get two outputs y=4 and y=-4 for input x=3.
Since, there exist more than one output values for a single input value, therefore it is not a function.
Therefore, the correct option is D.
The number x is a two-digit number.
• When x is divided by 9, the remainder is 1.
• When x is divided by 10, the remainder is 3.
What is the remainder when x is divided by 11?
Be sure to explain how you got your answer.
Answer:
x = 73
x ÷ 11 = 73 ÷ 11 = 6.636 or [tex]6\frac{7}{11}[/tex] or ( 6 remainder 7)
Step-by-step explanation:
1. In order to determine the value of x, we will first find a two-digit multiple of 9 that has a unit value of (2)
Multiples of 9 = 18, 27, 36, 45, 54, 63, 72, 81, ...
from the above, the multiple of 9 that has a unit value of '2' is 72 ( 7 tens and 2 units)
2. Next, we will add 1 to the multiple of 9 found in step 1 above, to create a unit value of '3'. This is because when the number is divided by 9, we want to have a remainder of 1, and when the number is divided by 10, and we want to have a remainder of 3
72 + 1 = 73 ( 7 tens and 3 units)
3. Finally, let us divide the number in step 2 above by 10
73 ÷ 10 = 7 remainer 3.
Now the number 73 satisfies the three conditions given in the question:
1) The number x is a two-digit number.
73 is a two-digit number
2) When x is divided by 9, the remainder is 1.
73 ÷ 9 = 8 remainder 1
3) When x is divided by 10, the remainder is 3.
73 ÷ 10 = 7 remainder 3
∴ x = 73
x ÷ 11 = 73 ÷ 11 = 6.636 or ( 6 remainder 7)

Answer:
x> -7/3y -7
Step-by-step explanation: -7y-3x<21
Step 1: Add 7y to both sides.
−3x−7y+7y<21+7y
−3x<7y+21
Step 2: Divide both sides by -3.
-3x/-3 < 7y+21/-3
x>-7/3y -7

The volume of the box is modeled by the function V (x) = 5x^2 + 5x. What is the volume when x= 4?
А-120 cubic units
B-30 cubic units
C-100 cubic units
D-45 cubic units
The volume of box at x = 4 is, 100 cubic units
What is mean by Cuboid?A cuboid is the solid shape or three-dimensional shape. A convex polyhedron which is bounded by six rectangular faces with eight vertices and twelve edges is called cuboid.
We have to given that;
The volume of the box is modeled by the function,
⇒ V (x) = 5x² + 5x
Now, At x = 4;
The volume of the box is,
⇒ V (x) = 5x² + 5x
⇒ V (4) = 5 × 4² + 5 × 4
⇒ V (4) = 5 × 16 + 20
⇒ V (4) = 80 + 20
⇒ V (4) = 100 cubic units

If you subtract 13 from my number and multiply the difference by -2 , the result is -44." What is 's number
Answer:
n = 35
Step-by-step explanation:
n - 13 x -2 = -44
distribute:
(n x -2) - (13 x -2) = -44
-2n - (-26) = -44
two negatives in front of a number makes it a positive number
so rewrite -2n + 26 = -44
-2n = -44 -26
-2n = -70
n = [tex]\frac{-70}{-2}[/tex]
n = 35
calc check (35 - 13) x -2 = 22 x (-2) = -44
On one play, a football team gained 9 yards. On the next play, the football team received a penalty
of -10 yards.
Answer:
If your asking what the sum of the yards is it would be -1
Step-by-step explanation:
First I would make a number line from -10 to positive 10. Then from zero add nine. Then subtract 10 from 9. Since 10 is bigger than nine it would be a negative number. Hope this helped.

Tristan and two of his friends purchased tickets to a school play. Tristan paid for all the tickets with a $50.00 bill and received $23.00 in change. If Tristan used a coupon for 25% off, what was the original price for one ticket?
Answer:
$36
Step-by-step explanation:
Tristan paid $50 for the tickets of the school play and was given $23 as change. The amount Tristan paid for the ticket is given as:
Price for ticket = amount paid - change = $50 - $23 = $27
Price for ticket = $27
Given that the ticket was sold at 25% off. Let x be the original price of the ticket, therefore:
x - 25% of x = $27
x - 0.25x = 27
0.75x = 27
x = 27/ 0.75
x = 36
Therefore the original price of the ticket is $36
Answer:
27.00

Benito drew a graph representing the number of miles he ran and the number
calories he burned. What is the unit rate in calories per mile? 3 4 250 1,000
Answer:
250
Step-by-step explanation:
1000 divided by 4, is 250
The unit rate would be 250 calories per mile which is the slope of the given linear function.
What is the unit rate?The unit rate of a linear function is defined as the slope of the linear function.
The slope is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
The given graph represents the number of miles he ran and the number of calories burned.
Taking two points as per the given graph :(2, 500), (6, 1500)
Let
x₁ = 2, y₁ = 500
x₂ = 6, y₂ = 1500
Substitute values in the formula to get
unit rate = (1500 - 500)/(6 - 2)
unit rate = (1000)/(4)
Apply the division operation,
unit rate = 250
Therefore, the unit rate would be 250 calories per mile

Suppose you can buy garden fencing in lengths of 50 feet at the local hardware store. A. If you bought 100 feet of fencing and wish to enclose a rectangular garden in your backyard, what should be the dimensions of your garden in order to maximize area?
Answer:
The answer is below
Step-by-step explanation:
Let the length of the rectangular area be L and W be the width of the rectangular garden hence:
Perimeter = 2(L + W)
There is 100 feet of fencing available which represents the perimeter, therefore:
100 = 2(L + W)
L + W = 100/2
L + W = 50
L = 50 - W
The area (A) = L × W
A = L × W
A = (50 - W) × W
A = 50W - W²
To get maximum area, we find the first derivative of the area and equate to zero
A' = 50 - 2W
50 - 2W = 0
2W = 50
W = 50/2
W = 25 feet
100 = 2(L + W)
50 = L + W
L = 50 - W = 50 - 25
L = 25 feet
To maximize area, the length and width should be 25 feet each
