First you move the 1/2to the other side of the = sign(when you move it over, you change the sign)
2x=(-1/2)32
Then get rid of the 2in 2x by doing the opposite sign of multiplication-division
x=(-1/2)32 divided by 2 is your answer
I really hope this helps!!
Answer:
7.5
Step-by-step explanation:
4x+5=2x+20
we know that
f(3) is the value of the function when x is equal to 3
so
For x=3
see in the graph
f(3)=6
see the attached figure
therefore
<u>the answer is</u>
f(3)=6
Answer:
The answer is (e)
Step-by-step explanation:
You know that the total time for one practice is (10+15+10+20+x). You can simplify that by adding like terms to get (55+x). You need that amount multiplied by three because he has 3 practices a week. so therefore you get 3(55+x). You distribute that three to both terms to get the simplest form which is 165 + 3x.
Answer:
D
Step-by-step explanation:
First let's notice a couple things:
- All the answers are in y = mx + b form
- Two of the answers don't have a value for b
- Pretty much all of the answers have a different m value
So let's go in order of our realizations.
Let's start with figuring out what b is. By simply looking at the graph, we can see that b = 0, because the line starts at (0, 0). Remember that b is when the line crosses the y axis, and our y value at x = 0 is 0.
This crosses out A and B.
Now let's find m, aka the slope. We can figure this out using the slope formula:

Awesome! So we've figured out that m = 7/2. This means our answer has to be D.
