What are the x- and y intercept graph of 6x-9y=18
first find the x intercept
6x-9y=18
6x-9(0)=18 substitute 0 for y
6x=18 simpify
x=3 divide each by 6.

find y intercept
6x-9y=18
6(0)-9y=18 substitute 0 an x
-9y=18 simpify
y=-2 divide each side by -9
the xintercept is 3 and the y intercept is -2

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!

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
