they are saying x = 3 so you would use the middle equation
so -4x becomes -4(3)
-4 * 3 =-12
Answer:
17 dollars
Step-by-step explanation:
If I know what you're trying to ask, then simply multiply 4 by 2, which is 8.
8+4=12.
12-29=17
Answer:
y=.5 or y=1/2
Step-by-step explanation:
3(0)+2y=1
3 x 0 = 0
0 + 2y = 1
2y = 1
Divide by 2
y=.5 or y=1/2
Answer:
I said, "ive been waiting here for ten minutes!"
"we're very busy today", she replied.
"how will I get home", I inquired.
Answer:
y = -140
Step-by-step explanation:
Y varies directly with x
y = kx
We know y = -20 when x =2, we can solve for k
-20 = k*2
Divide each side by 2
-20/2= 2k/2
-10 =k
y = -10x
Now we want to find y when x = 14
y = -10 *14
y = -140
