Answer:
Step-by-step explanation:
2.
Step where it was wrong ->
x-8 = 0
x=-8
They just put negative eight on the right side you have to cancel negative 8 out by adding negative 8 on both sides.
x-8=0
+8 +8
x=8 <- Right solution.
3.
Step where it was wrong ->
8(p-7) = 75
8p-7=75
Distributive Property you have to do 8 times p and 8 times -7, they just did 8 times p and forgot to do 8 times -7.
8(p-7)=75
8p-56=75 <- Do 8 * -7 in addition of doing 8 *p
8p=131
/8 /8
p = 16.735 or 131/8
323,000 is how you would write that
Answer:
B. Negative
Step-by-step explanation:
A line that has a negative "rise" (vertical change) for a positive "run" (horizontal change) has a negative slope. The slope is calculated from rise/run, so if the signs of rise and run are different, the slope is negative.
Any line that goes downward to the right has negative slope.
_____
Any line that goes upward to the right has positive slope.
It's 3/4 because (y2-y1)/(x2-x1)
This simplified is 126x so that is equivalent to this expression
