20% of 850 was paid in cash..
0.20(850) = 170 was paid in cash
so (850 - 170) = 680 was not paid in cash
Answer:
x=0, y = 3/2
Step-by-step explanation:
Ok, for substitution, you need to solve for y in terms of x, I'll do this for the first eqyation
8y=-7x+12
y=-7/8x+3/2, now plug in y in the second equation
-4x+2(-7/8x+3/2)=3, solve for x now
-4x-7/4x+3=3,
-4x-7/4x=0, x=0 now plug in 0 for either equation to solve for y
-4(0)+2y=3
2y=3, y=3/2
Point slope form: y1-y2=m(x1-x2)
Given the slope -4 and the set of coordinates (4,-9),
y+9=-4(x-4)
I plugged in the slope and coordinates. Since -9 came after a subtraction sign, I corrected the subtraction to addition, leaving the above point slope form equation.
I hope this helps :)
Answer:
9
