Answer:
Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)
Step-by-step explanation:
All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!

Trey is buying a computer on
sale. The origina Price was
4200. If the sale price is 5/6 of
the original Price . How much did
trey pay for the computer?
Answer:
3500
Step-by-step explanation:
To find a fraction of something just keep in mind that "of" means to multiply (when dealing with fractions and percents). In this case we want to know what 5/6 of 4200 is. So do (5/6)*4200 and that equal 3500.

Your boss sends you to the hardware store to buy tie down rope. He tells you to buy the best deal. What is the savings per unit between the best deal and worst deal?
A) $50.00
B) $25.00
C) 5 cents
D) 14 cents
Answer:
D. 14 cents
Step-by-step explanation:
At 10 feet for $7, that is 70 cents for every foot
At 20 feet for $13, that is 65 cents for every foot
At 50 feet for $28, that is 56 cents for every foot
At 100 feet for $57.50, that is 58 cents (rounded) for every foot
The best deal is 50 feet at 56 cents
The worst deal is 10 feet at 70 cents
So we do 70 - 56 = 14
So the answer is the savings per unit between the best deal and worst deal is 14 cents

A number is 6 times another number and their sum is 28.what are the two numbers
Answer: Let the 2 numbers be x and
sum of two numbers is 28....Eq 1: x + y = 28
sum of 6 times the 1st number and 3 times the 2nd number is 105....Eq 2: 6x + 3y = 105
Rearrange Eq 1 to solve for x.
x + y = 28
x = 28 - y --> Substitute into Eq 2, you get
6(28 - y) + 3y = 105
168 - 6y + 3y = 105
-3y = -63
y = -63 / -3 = 21
Now solve for x using Eq 1.
x = 28 - y = 28 - 21 = 7

Answer:
j = 7
Step-by-step explanation:
First expand the right hand side:
3 = 3(j-6)
3 = 3j - 18
Then we can move 18 to the left hand side and calculate for j.
3 = 3j - 18
21 = 3j
j = 7

6(6v +6) - 5 = 1 + 6v
Need answer with explaination
Answer:
v=-1
Step-by-Step Explanation:
Answer:
[tex]v=-1[/tex]
Step-by-step explanation:
[tex]6\left(6v+6\right)-5=1+6v[/tex]
Use the distributive property to multiply 6 by 6v+6:
[tex]36v+36-5=1+6v[/tex]
Subtract 5 from 36 = 31
[tex]36v+31=1+6v[/tex]
Subtract 6v from both sides:
[tex]36v+31-6v=1[/tex]
Combine like terms:
[tex]36v[/tex] and [tex]-6v[/tex] [tex]=30v[/tex]
[tex]30v+31=1[/tex]
Subtract 31 from both sides:
[tex]30v=-30[/tex]
Divide both sides by 30:
[tex]\cfrac{30v}{30}=\cfrac{-30}{30}[/tex]
[tex]v=-1[/tex]

evaluate m/-6/5 for m = 6 3/4
need an explanation pls^^
Answer:
- 5 [tex]\frac{5}{8}[/tex]
Step-by-step explanation:
[tex]\frac{m}{-\frac{6}{5} }[/tex] , is equivalent to
m ÷ - [tex]\frac{6}{5}[/tex] , substitute given value of m
= 6 [tex]\frac{3}{4}[/tex] ÷ - [tex]\frac{6}{5}[/tex] ( change mixed number to improper fraction )
= [tex]\frac{27}{4}[/tex] ÷ - [tex]\frac{6}{5}[/tex] ( leave first fraction, change ÷ to × , flip second fraction )
= [tex]\frac{27}{4}[/tex] × - [tex]\frac{5}{6}[/tex] ( cancel 27 and 6 by 3 )
= [tex]\frac{9}{4}[/tex] × - [tex]\frac{5}{2}[/tex] ( multiply values on numerator/ denominator )
= - [tex]\frac{9(5)}{4(2)}[/tex]
= - [tex]\frac{45}{8}[/tex]
= - 5 [tex]\frac{5}{8}[/tex]

If f(x) = 3x +9 x when f(x) = 30
Answer:
[tex]x=5/2[/tex]
Step-by-step explanation:
When [tex]f(x)=30[/tex], we have [tex]3x+9x=30[/tex].
Combining like terms on the right side, we have [tex]12x=30[/tex].
Finally, dividing by [tex]12[/tex] we get [tex]x=30/12[/tex].

Answer:
n = 3.16 units; p = 5 units
Step-by-step explanation:
to find the length of the lines you need to use the pythagorean theorem or a^2 + b^2 = c^2
in this case a is x, b is y, and c is the length
so for n it is:
1^2 + 3^2 = c^2 -->
1 + 9 = c^2 -->
10 = c^2
c = 3.16227766 or about 3.16 (this is n's length)
for p it is:
3^2 + 4^2 = c^2 -->
9 + 16 = c^2 -->
25 = c^2 -->
c = 5 (this is p's length)

Emerson purchased a game that was on sale for 18% off. The sales tax in his county is 8%. Let y represent the original price of the game. Write an expression that can be used to determine the final cost of the game.
Using decimal multipliers, it is found that the expression that can be used to determine the final cost of the game is given by:
[tex]C = 0.8856y[/tex]Decimal multipliers:The equivalent multiplier for an increase of a% is given by: [tex]\frac{100 + a}{100}[/tex]The equivalent multiplier for an decrease of a% is given by: [tex]\frac{100 - a}{100}[/tex]In this problem:
Purchase for 18% off, hence decrease of 18%, that is, [tex]\frac{100 - 18}{100} = 0.82[/tex].Sales tax of 8%, hence, an increase of 8%, that is, [tex]\frac{100 + 8}{100} = 1.08[/tex].Applying both multipliers, the expression is:
[tex]C = y(0.82)(1.08) = 0.8856y[/tex]
