Answer:
Actually it seems like there is an error (in my opinion)
Step-by-step explanation:
The first option shows Distributive property which cannot be categorised as associative property.
The third option seems right as associative property however on the R.H.S there is a 9, which is unneeded. So, the answer is a and c.

Answer:
see explanation
Step-by-step explanation:
The rule (x, y ) → (x + 2, y + 3 )
Means add 2 to the original x- coordinate and add 3 to the original y- coordinate, that is
A (1, 3 ) → A' (1 + 2, 3 + 3 ) → A' (3, 6 )
B (4, 7 ) → B' (4 + 2, 7 + 3 ) → B' (6, 10 )
C (6, 6 ) → C' (6 + 2, 6 + 3 ) → C' (8, 9 )

let h(x) be the inverse of f(x).If h(x)=-4+1 find f(x)
Answers
Assuming you meant to type h(x)=-4x+1
Answer:
[tex]f(x)=-\frac{1}{4}x+\frac{1}{4}[/tex]
Step-by-step explanation:
We know that, because [tex]h(x)[/tex] is the inverse of [tex]f(x)[/tex], that [tex]h(f(x))=x[/tex], so [tex]-4f(x)+1=x[/tex].
Aha! We can solve for [tex]f(x)[/tex]!
We subtract [tex]1[/tex] from both sides to get [tex]-4f(x)=x-1[/tex].
Finally, we divide both sides by [tex]-4[/tex] to get [tex]\boxed{f(x)=-\frac{1}{4}x+\frac{1}{4}}[/tex].

Chloe paid $21.18 for a large pizza including tax and delivery fees. She gave the delivery person
$25 and told the delivery person to keep the change. Did she give the delivery person a 20% tip?
Explain.
Answers
Answer:
No, she tipped about 18%.
Step-by-step explanation:
How much she tipped:
$25 - $21.18 = $3.82
To find the percentage, you can put this tip over the what she paid for the pizza.
[tex]\frac{3.82}{21.18} =0.18=18%[/tex]%
She only tipped about 18%

Answer:
f(6) = -7
Step-by-step explanation:
It is given that x = 6. Plug in 6 for x in the given equation:
f(x) = -x - 1
f(6) = -(6) - 1
Note that when you are subtracting two negative numbers, you are really adding the two numbers:
f(6) = -(6) - 1
f(6) = -7
When x = 6, f(x) = -7

Three consecutive even numbers are of the form [math]2k[/math], [math]2(k+1)[/math], [math]2(k+2)[/math]. We have that their sum is 120 therefore [math]\\2k + 2(k+1) + 2(k+2) = 120 \Leftrightarrow k+(k+1)+(k+2) = 60 \Leftrightarrow 3(k+1) = 60 \\ \Leftrightarrow k+1=20 \Leftrightarrow \boxed{k=19}.[/math

Answers
For the three types of candies, we will write a slope-intercept form equation. We know what m (slope) is for each equation, and there is no y-intercept because there is no starting point.
Equations:
Mints: y=.96x
Chocolates: y=4.70x
Lollipops: y=.07x
Using the given information, we can use the equations in function form. We know what x (input) is for all three types of candy, and that will give us y (output), which is the total for that candy type.
Solving:
Mints: y=.96(.75)
Chocolates: y=4.70(1.5)
Lollipops: y=.07(15)
We just input our information into the equations. Using logic, we know that we will have to multiply the cost of the candy by the number of candies to get the total of the three types.
Totals:
Mints: y=.72
Chocolates: y=7.05
Lollipops: y=1.05.
*Recall that y=total cost of candy for each type.
Now, we just simply add the three costs up to get the total sum that the candy will cost:
.72+7.05+1.05=8.82
Therefore, all the candy will cost $8.82.

Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost $20. The items she bought cost a total of $160 before tax was added. What was the cost of each sweat?
Answers
Answer:
$35
Step-by-step explanation:
first we need to find the amount of money the sweaters cost alone.
so we first subtract the total (160) - the skirt price (20) which is 140
now we divide it by 4 to find the price of each seater, as they all cost the same.
so 140 divided by 4 = 35
answer: $35

2.5(4-x)+12=21-4(2.5x+7)
Answers
Answer:
x=-58/15
Step-by-step explanation:
distribute first 10-2.5x+12=21-10x-28
Simplify(add the numbers) 22-2.5x=-7-10x
move the variable to the left side 22-2.5x+10x=-7
move the constant to the right side -2.5x+10x=-7-22
simplify like terms 7.5x=-29
divide by 7.5 x=-58/15
alternate forms are x=-3 13/15 or x=-3.86
Write the equation of the line in fully simplified slope/intercept form
Answers
Answer:
y = m x + b standard form for straight line
m = (y2 - y1) / (x2 - x1)
When y2 = 12, x = -6
when y = 0, x = -2
m = (12 - 0) / (-6 - (-2)) = -3
so y = -3 x + b
Also, when x = 0, y = -6
Our equation is
y = -3 x - 6
As a check try x = -2
y = (-3 * -2) + (-6) = 0 as the graph shows
