7+7+7+7=28
7x4= 28
If you are learning multiplication you can use those
X intercept=(1,0)
Y intercept=(0,-2)
You get x by substituting 0 for y and you get y by substituting 0 for x therefore to find y coordinates,
2(0)-2=y
0-2=y
-2=y so (0,-2)
And to find x coordinates,
2x-2=0
2x=2
2x/2=2/2
X=1 so (1, 0)
Answer:
27
Step-by-step explanation:
-21/-7 =3 so x is 3y. if you plug 9 in for y you get 3(9) then you multiply and get 27.
The answer is C. 3 to the first power is 3. 3 to the second power is 9. 3 to the third is 27, and so on.
