Find the domain of the function represented by the graph. Determine whether the domain is discrete or continuous.
Calculate the vertices of the figure given by A (1, 3), B (4, 7), and C(6, 6) after being
translated using the rule (x, y) > (x + 2, y + 3).
The new points are:
A’
B’
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 )
I HOPE IT WILL HELP YOU.
Thank you.

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?
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

Solve for x. Show each step of the solution.
2.5(4-x)+12=21-4(2.5x+7)
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

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.
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%
A company rents out 19 food booths and 20 game booths at the county fair. The fee for a food booth is $200 plus $7 per day. The fee for a game booth is $65 plus $5 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
$2715
Step-by-step explanation:
Given that 15 food booths were rented out for ‘d’ days at $100 plus $5 per day. On the food booths only, the company will earn 15($100+$5d) = $1500 + $75d Given that 20 game booths were rented out for ‘d’ days at $50 plus $7 per day. On the game booths only, the company will earn 20($50 + $7d) = $1000 + $140d
The total amount that the company is paid is therefore, $1500 + $75d + $1000 + $140d = $2500 + $215d

Is line p || to line q? Why?
Step-by-step explanation:
yes, because the angles match. per rule of intersecting lines the angles in one side of an intersected line are the same but mirrored on the other side of the line.
since q behave exactly as p would regarding the intersecting angles, they are parallel.

let h(x) be the inverse of f(x).If h(x)=-4+1 find f(x)
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].
Two numbers multiply to be 20 and add to be 12. What are the numbers?
Answer:2 and 10
Step-by-step explanation:
given f(x)=-x-1 find (6)
Answer:
[tex]{ \rm{f(x) = - x - 1}} \\ \\{ \rm{f(6) = - 6 - 1}} \\ \\ { \rm{f(6) = - 7}}[/tex]
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

The number that goes with O is
The number that goes with 16 is
The number that goes with 10 is
The number that goes with 94 is
x= 0
f(0)= 2(0+2)+ 4(0)= 4
f(16)= 2(16+2)+ 4(16) = 100
f( 10) = 2(10+2) + 4(10)= 64
f(94)= 2( 94+ 2) + 4(94) = 568

Write the equation of the line in fully simplified slope/intercept form
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
