Answer:
8
Step-by-step explanation:
compare the divisor x+1 with x-a which will be -1 then use remainder theorem to get your answer
Answer: All the factor pairs of 28 are:
1, 2, 4, 7, 14, 28
Step-by-step explanation:
We can move from the outsides on opposite sides (->this way<-) and pair the numbers together to make sets of the number that will multiply to make 28
Answer:
C
Step-by-step explanation:
5+3 = (-1)-(-9)
5+3 =(-1)+9
8 = 8
Y=Mx+b so it is Letter C)
Answer:
r = 3.
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope.
Finding the slope of a line, given two points:
When we are given two points of a line, the slope of the line is given by the change in y divided by the change in x.
Points (4,r), (r,3)
Change in y: 3 - r
Change in x: r - 4
Slope is 0, so:



The value is r = 3.
