Just around the 15 and 3. So it would be
(15-3)x4+9=57
This is because (15-3)= 12
12x4=48
48+9= 57
Answer:
4
Step-by-step explanation:
4x+5+3x-2=31
7x+3=31
7x=28
x=4
Answer:
9 - 7x - x²
Step-by-step explanation:
-4x+2x2-x²+5-3x = -4x-3x+2x2+5-x²
I arranged the like terms together so it is easier to do the calculations.
-4x-3x+2x2+5-x² = -7x+4+5-x²
Simplify.
-7x+4+5-x² = 9-7x-x²
It would be 5%. I know the answer is right I just don’t know how to explain it. Sry. But I hope this helps.
Y=4x+4
I think this is it u just have to simplify to get it to y=mx+b
