4, I cannot fail this if I do I have a F in math!! Please make sure u know it’s correct I can’t do it alone.

X= -45

Step-by-step explanation:

If graphed on desmos, the line touches the x axis at (-45,0)

Also, if in the equation you substitute y for 0, then you will get -45

Do you still need answers to the rest of your questions? I'll help u pass your test if u need

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
