14. The answer is A; 8 is the opposite reciprocal of -1/8, which is what you need for perpendicular slope.
15. The answer is C; you can guess and check by plugging points into the equation.
Answer:
4,684 km
Step-by-step explanation:
Answer:
(13/8, -5/4)
Step-by-step explanation:
substitute the value of y
{y=6x-11
2x-3y=7
solve the equation
2x-3(6x-11)=7
Substitute the value of x
x=13/8
Solve the equation
y=6x13/8-11
A possible solution is
y=-5/4
Check the solution
(x,y)=(13/8, -5/4)
Simplify
{-5/4=6x13/8-11
2x13/8-3x(-5/4)=7
The ordered pair is a solution
{-5/4=-5/4
7=7
<em>Solution </em>
(13/8, -5/4)
