There is one input being mapped into two different outputs, so this is not a function. The correct option is D.
What is a function?A function is a relation that maps elements from one set (the domain) into elements from another set (the range). Such that each element from the domain can be mapped into only one element from the range.
In this case, the table is:
Gallons of Gas Used: 12 15 18 12 14 16Miles Driven: 300 400 450 350 400 450So, the input "12" appears twice, the first time is mapped into 300 miles, and the second time is mapped into 350.
So the same value from the domain is being mapped into two different values of the range, meaning that this is not a function. So the correct option is D.

I would solve this by calculating the percentage of dislikes that makes up to this amount of likes:
First one, "The True Science of Parallel Universes" would be:
5/300)*100 = 1.66
Second one, "did the Past Really Happen?" would be:
7/400)*100 = 1.75
The first one has less dislikes compared to likes. So "The True Science of Parallel Universes" is the video that is better liked
Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, HCF). When graphed, the function gives a line with a slope of 1.45. See the figure below.
If the monthly cost for 13 HCF is $46.33, what is the monthly cost for 17 HCF?
The monthly cost for 17 hundred of cubic feet is $52.13.
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the bill paid for x HCF of water.
The slope is 1.45, hence m = 1.45.
The monthly cost for 13 HCF is $46.33, hence:
46.33 = 1.45(13) + b
b = 27.48
y = 1.45x + 27.48
For 17 HCF:
y = 1.45(17) + 27.48 = 52.13
The monthly cost for 17 hundred of cubic feet is $52.13.

Marie has $60,000 in a savings account that earns 7% interest per year. How much will she have in 4 months?
Answer:
21,400
Solving steps:
Since, Marie has $60,000 in a savings account that earns 7% interest per year.
Find: How much will she have in 4 months.
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: solution[/tex]
Step 1: Find the money for the 7% rate
=> [tex] 60000 \times \frac{7}{100} [/tex]
=> [tex] \frac{60000}{1} \times \frac{7}{100} [/tex]
cancel the two zeros of 60,000 and 100
=> 600 × 7
=> 4,200
Add 4,200 to 60,000
=> 64,200
per year = 64,200
Now, divide 64,200 by 12
since 12 months to make one year
=> 64,200 ÷ 12
=> 5,350
now multiply it by 4 months she gets 5350 per month
=> 21,400

Please note that the units for each side MUST be the same (or if they're different, then the lengths have to be equivalent).
Looking at the answer choices, we can see that the last answer choice is a 1 yd by 1 yd by 1 yd cube, therefore it is a unit cube.

Order the steps to factor the quadratic trinomial completely.
Answer:
1, 4, 3, 5, 6
Step-by-step explanation:
5(5x² - 9x) = 45x + 40 ← distribute parenthesis on left side
25x² - 45x = 45x + 40 ← subtract 45x + 40 from both sides
25x² - 90x - 40 = 0 ← factor out 5 from each term
5(5x² - 18x - 8) = 0
5(x(5x + 2) - 4(5x + 2))
5(x - 4)(5x + 2)
Answer:
The order is: 1, 4, 3, 5, 6
Step-by-step explanation:
5(5x² - 9x) = 45x + 40
25x² - 45x = 45x + 40
25x² - 90x - 40 = 0
5(5x² - 18x - 8) = 0
5(x(5x + 2) - 4(5x + 2)
5(x - 4)(5x + 2)
The order is: 1, 4, 3, 5, 6

Answer:
aₙ = a₁ * 2ⁿ⁺¹
Step-by-step explanation:
a₁ = 6
a₂ = 12
a₃ = 24
Note a₂/a₁ = 2 = a₃/a₂
So it is a geometric sequence with common ratio of 2
a₂ = a₁ * 2 = a₁ * 2¹ = a₁ * 2²⁺¹
a₃ = a₂ * 2 = a₁ * 2 * 2 = a₁ * 2² = a₁ * 2³⁺¹
Then
aₙ = a₁ * 2ⁿ⁺¹

D.
y = –1
Answer:

Add 5 to both sides
4 + 5 + 3y = 6y
9 + 3y = 6y
Subtract 3y to both sides
9 = 6y - 3y
9 = 3y
Divide 3 to both sides
3 = y

Find the equation of the axis of symmetry of the parabola. Each box in the grid represents 1 unit.
Enter the answer as an equation.
Answer:
The axis of symmetry of this parabola will be the line x=−b2a .
Step-by-step explanation:
Graph the parabola y=x2−7x+2 .
Compare the equation with y=ax2+bx+c to find the values of a , b , and c .
Here, a=1,b=−7 and c=2 .
Use the values of the coefficients to write the equation of axis of symmetry .
The graph of a quadratic equation in the form y=ax2+bx+c has as its axis of symmetry the line x=−b2a . So, the equation of the axis of symmetry of the given parabola is x=−(−7)2(1) or x=72 .
Substitute x=72 in the equation to find the y -coordinate of the vertex.
y=(72)2−7(72)+2 =494−492+2 =49 − 98 + 84 =−414
Therefore, the coordinates of the vertex are (72,−414) .

C.Starting at -7 on a number line,Darcy moved 4 units to the right. What integer did Darcy land on?
Please answer thiss, thank you guys so much!!!!!!! :)
Answer:
a. -1
Subtracting 6-7 would give you -1. Negative 1 is 7 units from the number 6.
b. -5 and 15

The key thing to focus on is the phrasing "starting at the age of 8"
Specifically, your teacher wants the starting height when Mia was 8 years old. That height being 52 inches.
The 7 inches refers to how much she had grown over the 2 years, which is part of the rate of change (and will be part of the slope).
Side note: 52 inches = 4 ft, 4 inches

Answer:
$1107.55
Step-by-step explanation:
3,589.90 x .0590/12 = $17.65
3,589.90 + 17.65 =3,607.55
3,607.55 - 2,500 = $1,107.55
6. Find the value of each missing variable.
Answer:
x = 110
y = 102
z = 82
Step-by-step explanation:
Angles that create a line are equal to 180
x + 70 = 180
x = 110
y + 78 = 180
y = 102
A quadrilateral's angles add up to 360
110 + 78 + 90 + z = 360
278 + z = 360
z = 82

Frankie is saving his money to buy the new Nintendo Switch. The switch is on sale for $300. He already has $215 saved up and his mother tells him she will pay him $7 for each extra chore he completes around the house. What is the minimum number of chores he must complete to have enough money for the Switch?
A. 12 chores
B. 14 chores
C. 13 chores
D. 11 chores
Answer:
C
Step-by-step explanation:
Because nintendo price=300$
He has 215$
1 chore he does=7$
Meaning if he did 10 chores he get's 70$ added so he did 10 now he has 285$ If he does 2 more chores that is 14$ more added.
So he now has 299$ so he done 12 chores and he needs 1 more dollar so if he did 1 more he gets 306$ and that was the least amount of chores he could do if he wanted 300$
And there's your answer
Hope this helps have a awesome day:)
