ANSWER
The solution is

EXPLANATION
The given equations are:

and

We multiply equation 1 by 3 to get,

We multiply equation 2 also by 2 to get,

We subtract equation 4 from equation 3 to get,

This implies that,

We put this value of y into any of the equations say equation 2

Simplify

Group like terms

Simplify,

Divide both sides by 3 to get,

Therefore the solution is

The correct answer is option D.

Answer:
Step-by-step explanation:
take two points on the line ,i take (-4,0) and (0,-2)
slope=(y2-y1)/(x2-x1)=(-2-0)/(0+4)=-2/4=-1/2
Answer:
200
Step-by-step explanation:
T = x * (1/H)
x = T*H
x = 2800
so for H = 14
T = 2800 * (1/14) = 200
8x - 32 = 6 - 9x
17x = 38
x = 38/17
