Answer:
A. No solutions
Step-by-step explanation:
2x-2x=-9
0= -9
Since 0 does not equal -9, there are no solutions.
Answer:
We know that when x= -10, y= -17.
So, if we put those into direct variation "y=kx", we get
-17= k(-10)
k = -17 / -10
Now we put the value of "k" into the formula and we get A (y= 17/10x )
Answer: x=-1
Step by step:
2|x+6|+9=19
Subtract 9 from both sides.
2|x+6|=10
Divide both sides by 2
|x+6|=5
Use the definition of absolute value.
x+6=5
Subtract 6 on both sides
x=-1
