It would be C . You can figure it out by seeing how many times -4 goes into -28, which is 7 times. If you're not sure whether it is negative or positive then you could either use a calculator to check or remember this rule a negative times a negative is a positive which means your answer would have been 28 not -28.
Answer:
y=5/2x-16
Step-by-step explanation:
First, we want to find the slope of the original line.
m= -4+8/-1-9
m= 4/-10
m= -2/5
Because we want the perpendicular bisector, we will need the slope to be the opposite reciprocal. Therefore, our slope is
m=5/2
Now, we want to find the midpoint of the line.
9-1/2
8/2=4
-8-4/2
-12/2= -6
So, the midpoint is (4,-6)
Using the information we have, we now can find b.
-6=5/2(4)+b
-6=10+b
-16=b
That gives us our equation
y=5/2x-16
The eqaution i use for this is:
(cross multiply)
(25.83)(100) = (x)(49.5) (multipy)
2583 = 49.5x (divide by 49.5 on both sides)
52.181818182 = x

Answer:
10.5 in. ²
Step-by-step explanation:
a = (b × h) ÷ 2
a = (7 × 3) ÷ 2
a = 21 ÷ 2
a = 10.5
