Answer:
C
Step-by-step explanation:
Noting that
+ (- ) is equivalent to subtraction
- (- ) is equivalent to addition
Given
13 + (- 12) - (- 5)
= 13 - 12 + 5
= 1 + 5
= 6 → C
Answer:
Mabe C? I'm not positive but I am on a test myself
So standard form is Ax+By=C
Since the problem is already in that form you don’t need to switch it around however A has to be more than 0 (so positive). Divide the equation by -3 to get the answer x-4y=-8
Answer:
Check explanation
Step-by-step explanation:

Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (0 - 8)/(-9 - (-4))
m = (0 - 8)/(-9 + 4)
m = (-8)/(-5)
m = 8/5
Answer: Choice C) 8/5
