A variable needs to be eliminated to solve the system of equations below. Choose the correct first step.
8x + 6y = 66
8x - 4y = -4

A. Add to eliminate y.
B. Subtract to eliminate x.
C. Subtract to eliminate y.
D. Add to eliminate x.

the answer would B

Step-by-step explanation:

When you subtract the x will be eliminated because 8 -8 is 0

Hope it helps:)

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
