Answer:
x=3
Step-by-step explanation:
13= -2 (x+1) +7x (given)
13+-2x - 2 +7x (distributive property of multiplication over addition)
13 + 5x -2 (combine like terms)
15 = 5x (addition property of equality)
3 = x (division property of equality)

15. If gasoline costs $4.02 per gallon, your tank holds 13 gallons, and your car averages 26 miles per gallon,
a) If your tank is full, how far can you drive before you run out of gas?
b) If your tank were empty, how much will it cost to fill up your tank?
Answer: a) 338 miles
b) $52.26
Step-by-step explanation: To get the amount of miles that your car can drive before running out of gas, you just multiply how many gallons you have by how many miles each gallon lasts. Then, to get the cost of all the gas, you multiply the cost of the gas by how many gallons you need.

-19
O 11
O 12
help
Answer:
-19
Step-by-step explanation:
[tex]f(x) = 5 , f(x) = -3x-4[/tex]
We just have to plug in 5 into f(x) and solve for y
[tex]f(5) = -3(5) - 4 \\f(5) = -15 - 4 \\f(5) = -19[/tex]
The temperature dropped 5 °F every hour for 5 hours. What was the total number of degrees the temperature changed in the 5 hours?

Zoey signed up for a streaming music service that costs $7 per month. The service allows Zoey to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $0.75 per song. How much total money would Zoey have to pay in a month in which she downloaded 45 songs? How much would she have to pay if she downloaded s songs?
Answer:
the answer is 60 $ but with the charge of 7 its 67.
Step-by-step explanation:
45 divided by 0.75 is 60.
Answer:
Cost for 45 songs: 40.75
Cost for s songs: 0.75s + 7
Step-by-step explanation:
Since its $0.75 per song, you have to multiply 0.75 to 45. You already need to pay $7. The equation would be 0.75s + 7 and the answer would be 40.75.

Paul bought a student discount card for the bus. The card allows him to buy daily bus passes for $1.30.
After one month, Paul bought 21 passes and spent a total of $33.30.
Help pls
Answer:
Paul spent 6 dollars on the student discount card.
Step-by-step explanation:
If each pass is $1.30, simply divide 21 by 1.30
You should get 27.30
Next, subtract 33.30 by 27.30, getting 6.
On a piece of paper graph y= 2x-3. Then determine which answer matches the graph you drew. (there is 4 options not just three)
Answer:
A
Step-by-step explanation:
since the slope (2) is positive the graph is similar to y=x, so graphs B and D are eliminated
so when x=1 we have
y=2(1)-3
y=2-3
y=-1
so the point is (1,-1), graph C eliminated
so it's A
The standard equation for finding the equation of a line is expressed as
y = mx + b
m is the slope of the line
b is the y-intercept
Before we can plot the equation of a line, we must know the slope and the y-intercept of such line.
Given the equation of a line to be plotted expressed as y = 2x - 3
Compared with the standard equation;
mx = 2x
m = 2
Hence the slope of the line is 2
Similarly;
b = -3
Hence the y-intercept is 3.

-2(x-3) < 2x - 4
Answer:
2.5 < x or 5/2 < x
Step-by-step explanation:
Start by distributing the -2 to the parenthesized numbers.
-2*x and -2*-3
You end up with -2x and 6 (negative times a negative gets positive).
-2x+6 < 2x-4
Next you need to get your variables, x, on one side. It can be either but I like addition so lets take the -2x and move it to the opposite side.
You'll need to add 2x to both sides since its a negative number.
-2x(+2x)+6 < 2x(+2x)-4
-2+2 is 0 and 2+2 is 4.
6 < 4x-4
You want to get the variable alone now so you'll want to add the 4 to the other side (because its negative you add. If it was positive you'd subtract).
6(+4) < 4x-4(+4)
6+4 is 10 and -4+4 is 0.
10 < 4x
You want to divide out the 4 from 4x because you want the variable alone. Divide 4 from both sides
10(/4) < 4x(/4)
Now depending on if you want a variable or a fraction 10/4 can be 5/2 (simplified fraction) or 2.5 (decimal). 4x/4 gives you x.
2.5 (or 5/2) < x
Hope that helps.

Are the lines parallel, perpendicular, or neither
Answer:
perpendicular
Step-by-step explanation:
The first equation can be written in slope-intercept form as ...
y = -1/2x - 3
In this form, we see that the slopes of the two lines are -1/2 and 2, so the product of their slopes is -1. That means the lines are perpendicular.
