how do i solve 3x-8x=-40

Answers

Answer 1

Answer:

The answer is 8 below is how you do it.

Step-by-step explanation:

first combine like terms 3x-8x

then you will have 5x

then do 40/5 and you will get x=8

Answer 2

Ok so to solve for x you need to isolate the variable. Usually, when solving an equation the first step would be to get all of the variables of x on the same side but this equation is already set up that way. Since 3x and 8x are both of the variable x you can simply subtract them and you would be left with:

-5x=-40

Now what you want to do is completely isolate x to get it by itself in which you would divide both sides by -5. Remember *When solving an equation you must do the same math to both sides.

-5x/-5=-40/-5

x=8

So the answer would then be 8. Also remember you can always check to see if your equation is correct by plugging your answer into the original equation

3(8) - 8(8) = -40

24 - 64 = -40

-40 = -40

Hope this helped :)

dani takes her two friends out for lunch. dani's meal costs $5. 72 and her friends' meal are $4. 89 and $7. 30. dani pays for the meals with a $20 dollar bill. how much change should she get?

Answers

Your answer is : $2.09

To find this answer you first need to find out how much money Dani spend.The equation for this is (5.72+4.89+7.30=17.91).The last step is to subtract the amount Dani spent by the amount she paid so new equation is (20.00-17.91=2.09)The answer is $2.09

$5.72+$4.89+$7.30=$17.91
$20.00-$17.91=$2.09

Dani will get $2.09 back. :)

19. The absolute value equation of the graph is: y — | x - 0 | + 2 where (0,2) is the vertex.

Domain: (-∞, ∞)
Range: (-∞, 2]

A function is a relation in which no two ordered pairs have the same first component (inputs/x-values/domain) and different second components (outputs/y-values/range).

In determining whether a given relation is a function, we need to ask ourselves, does every first element (or input) correspond with EXACTLY ONE second element (or output)? 

In the case of an absolute value function, its relation is a function because each input corresponds to exactly one output. To demonstrate, I performed a Vertical Line test to show why it is a function.

The Vertical Line Test (VLT) allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function. As the attached graph of the absolute value function, EACH vertical line drawn crosses the graph only once. This graph passes the VLT, making it a function.


20.)

The set of first components (x-coordinates) in the ordered pairs is the DOMAIN of the relation.

The set of second components (y-coordinates) is the RANGE of the relation.

Domain: {-2, -1, 0, 1}.
Range: {4, 3, 2, 1, 0}.

The given relation is NOT a function. As you can see from the given diagram, the input value of 2 corresponds to two output values: 4 and 0.

Robert started working at a local burger restaurant and earns $9.00 per hour. Which graph shows the relationship between his earnings and the number of hours he worked?

Answers

A

Step-by-step explanation:

Graph A would be the graph the shows the relationship between his earnings and the number of hours he worked, because after 1 hour of work he would have made 9$ (1,9), after 2 hours he would have made 18$ (2,18), and after 3 hours of work he would have made 27$ (3,27). All these are placed on the graph. Hope this helps!

Answers

Answer:

1) x + 4 = 11

Subtract 4 on both sides, to get x = 7 .

2) x + 3 = 24

Subtract 3 on both sides, to get x = 21 .

3) 4x = 12

Divide 4 on both sides, to get x = 3 .

4) 5x + 3 = 33

First subtract 3 on both sides to get

5x = 30, now divide 5 on both sides, to

get x = 6 .

5) 8x + 5 = 3x + 20

First subtract 5 from 20 in order to

move it, now you have 8x = 3x + 15 .

Next subtract 3x from 8x in order to

move it, now you have 5x = 15 . Lastly

divide 5 on both sides, to get x = 3 .

1) 1/2 x = 4

Multiply both sides by 2, to get 1x = 8,

or x = 8 .

2) 4/3 x = 4

Multiply both sides by 3, to get 4x = 12 .

Next divide 4 on both sides to get

x = 3 .

3) 2x + (-4) = 8

Add 4 on both sides, to get 2x = 12 .

Next divide 2 on both sides to get

x = 6 .

4) 1/3 x + 1/2 x = 20

First multiply the denominators to get a

common denominator of 6 and then

add 3 and 2, to get the numerator. Now

you have 5/6 x = 20 . Next multiply 6

on both sides to get 5x = 120 . Lastly

divide 5 on both sides to get x = 24 .

5) 1/3 x = 1/5 x + 10

First multiply the denominator to get a

common denominator of 15 and then

subtract 3 from 5 to get the numerator.

Now you have 2/15 x = 10 . Next

multiply 15 on both sides to get

2x = 150. Lastly divide 2 on both sides

to get x = 75 .

Set up a proportion: 150/100 = 210/x. x=136% or your investment returned you 36% of your initial 150.

h(x)=x2-x;h(5) find function

Answers

Answer:

h(5) = 20

Step-by-step explanation:

Assume that '2' is an exponent.

So the question for you should be:-

[tex] \displaystyle \large{h(x) = {x}^{2} - x}[/tex]

We want to find h(5); we substitute x = 5 in.

[tex] \displaystyle \large{h(x) = {5}^{2} - 5}[/tex]

5^2 is 5•5 = 25.

[tex] \displaystyle \large{h(x) = 25 - 5} \\ \displaystyle \large{h(x) = 20}[/tex]

Therefore, h(5) is 20.
