Answer:

C.) -3/2

Step-by-step explanation:

To find the slope you need to use the formula: m = y2 - y1/x2 - x1

Point: (-2,1) and (2,-5)

m = y2 - y1/x2 - x1

m = -5 - 1/2 - (-2)

m = -6/2 + 2

108 is 36% of what number? Write and solve a proportion to solve the problem.

Answers

Answer: 300

Step-by-step explanation:

Let the number be represented by x.

Therefore, based on the information given in the question, this can be expressed as:

36% of x = 108

36/100 × x = 108

0.36 × x = 108

0.36x = 108

x = 108/0.36

x = 300

Therefore, the number is 300

so first we need to substitute 3 into the expression
3^2 + 3 / 3 - 1
9 + 3 / 2
12 / 2 = 6
hope this helps! :)
Answer: 6
If x=3 we first need to find the value of all the x’s is this equation starting with x to the power of two
3•3=9
now we add 3 to nine since it is directly next to it
3+9=12
for the divisor we have x-1
(3)-1=2
so now that we have all the values we simply divide
12/2=6
