mylen [45]

Answer:

15 miles per gallon

Step-by-step explanation:

If a car travels 45 miles and uses 3 gallons of gas than to find how many miles can be traveled using 1 gallon, you do 45/3, miles/gallons to get 15 miles/1 gallon.

Please help me work plz the narow edge you cant see is a 7

natta225 [31]

Answer:

13

Step-by-step explanation:

You use pemdas to figure this out, so you do whats in the parentheses first, 2x-6, but instead you do 2(4)-6 and when your solving stuff in the parentheses you apply pemdas again to figure out what to do, so you multiply 2x4 first bcz m is before s, and then you do 8-6 bcz there's nothing else to do in the parentheses. now that your done with the parantheses you currently have 3x3 +2(2). now you dont have p or e but you do have m and when you have multiple instances of multiplication you do it left from right, so you do 3x3 first and get 9 and then you do 2x2 and get 4. now you have 9+4 and since you have nothing else to do you add and you get 13.

Solve the following systems of equations algebraically using elimination<br> -2x+4y=4<br> 3x-4y=2

krok68 [10]

Hey there!

When solving systems of equations by elimination, what we do is we remove one variable by combining the equations and then we solve for one variable.

How does this work?

Well, let's say we have 2x in one equation and 2x in the other equation. If we combine the equations, it will simply be 4x! What we need to do is multiply one of the equations by -1, which will make one of the 2x's and -2x. Then, if we combine the two equations, our x's will be cancelled out and we can solve for y.

In this case, we don't need to change any of the equations because we have 4y in one equation and -4y in the other, so we will just add the equations and then solve for x.

-2x+4y=4

+

3x-4y=2

=

x=6

Now, we plug this into one of our equations to find y.

18-4y=2

-4y=-16

y=4

Therefore, our solution is x=6 and y=4.

I hope this helps!

Complete the statements for the graph of f(x) = |x|. The domain of the function is . The range of the function is . The graph is

ioda

Answer:

Domain of f(x): All real numbers

Range of f(x): $f(x) \geq0$ ---> [0, ∞)

The graph is over the interval (0, ∞)

Step-by-step explanation:

The function absolute value of x that is written: f(x) = | x | assigns only positive values to f(x) at any value of x.

For example, if for f(x) = | x | we make

f(-23) = | -23 | then the absolute value of x "transforms" the number -23 to +23.

Then f(-23) = | -23 | = 23

This means that f(x) will be positive for any value of x.

Therefore, we can conclude that:

Domain of f(x): All real numbers

Range of f(x): $f(x) \geq0$ ---> [0, ∞)

The graph is over the interval (0, ∞)
