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)

Answers

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.

Are the lines parallel, perpendicular, or neither

Answers

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.

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?

Answers

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.

-2(x-3) < 2x - 4

Answers

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.

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?

Answers

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.

Which of the following is the solution set of the given equation?

A) {-10}
B) {-4}
C) {8}

Answers

x= -10

first you distribute the -2 throughout (x+6) which then becomes, -2x -12
After you’ve done that plug it in the equation, the equation should be, x-3-2x-12=-5
Now combine like terms. After it should look like, -x - 15 = -5, Add 15 to both side. It should be, -x = 10
Finally divide by -1 on both sides and that should give you x= -10
