Answer:
8
Step-by-step explanation:
77+50=127
180-127=53
7x-3=53
7x=53+3
7x=56
x=56/7
x=8
3x(6x-1)+4(6x-1)
(3x+4)(6x-1) is the answer
SOLUTION
If the table represents an inverse variation, it means that y is inversely proportional to x, written as

Removing the proportionality sign and introducing a constant k, we have

In the first column, we have x = -4 and y = 3.5. Substituting these values for x and y, we have

So, if it's an inverse variation, the relationship would be

In the second column, x = -2 and y = 7.
Now lets substitute the value of x for -2. If we get y to be 7, then the relationship is an inverse variation
We have

Since we got y = 7, the relationship is therefore an inverse variation.
The constant k = -14
The equation for the inverse variation is
Answer is -8
(-1)+(-7) turns into (1)+(7)=8 and then back to original which will be -8
