Answer:
Step-by-step explanation:
<u>Use two pairs of points to work out the equation: </u>
<u>Find the slope:</u>
- m = (5 - 1) / (2 - 1) = 4/1 = 4
<u>Find the y-intercept:</u>
- 1 = 4*1 + b
- b = 1 - 4
- b = - 3
<u>The line is:</u>
Correct choice is D
The answer is c mean = median
Answer:
P(n,4)÷P(n,2)
= (n-2)(n-3)
20 = 4 × 5 (two consecutive numbers)
(n-2)(n-3)=5×4
n-2=5
n=7
Answer:
y = 15
Step-by-step explanation:
In a parallelogram, opposite lengths are equal.
So it means that the length (5y - 20) is equal to (2y + 25).
Now that there is only one variable in the equation, we can solve for the variable.
5y - 20 = 2y + 25
5y - 2y = 25 + 20
3y = 35
y = 15
I believe you just multiply the two numbers together and get 2.665
