Answer
Step-by-step explanation:
The answer would be y=-x-3. 3x+3y=-9 is in standard form and you want it to be in y=mx=b form (slope-int) so subtract 3x by both sides. Now, you have 3y=-3x-9. Divide 3 to both sides, now you will get y=-x-3.
You find the square root of 576. The answer is 24
8z-22=3(3z+11)-z
9z-22=9z+33
-22=33
or
0=55
either way no solution
I believe the answer is d
Cross multiply.
14/12=x/18
14 x 18 = 252
252/12= 21
so x=21
