Explanation
Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. Show all work.
A) 4 ⋅ 6 + 5 ⋅ 7 + 6 ⋅ 8 + ... + 4n( 4n + 2) = 4(4n+1)(8n+7)/6
B) 1^2 + 4^2 + 7^2 + ... + (3n - 2)^2 = n(6n^2 - 3n - 1)/2
For the given statement Pn, write the statements P1, Pk, and Pk+1.
C) 2 + 4 + 6 + . . . + 2n = n(n+1)

What is the slope of y= 6x + 6?
Answer:
6
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept.
Answer:
6
Step-by-step explanation:
Slope-intercept form is written y=mx+b.
y= always by itself (in slope-intercept form)
m= the slope (in this case, 6)
x= the letter that the slope is always next to
b= the y-intercept

Step-by-step explanation:
i hop it helps
There are 15 boys in Ella's class and 16 boys in Minh's class.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, The ratio of boys to girls in Ella's class is 3 to 4. The ratio of boys to girls in Minh's class is 4 to 5.
Each class has a total of 20 girls and assuming each class has a total of x students.
∴ 4x/7 = 20.
4x = 140.
x = 35.
No. of boys = 15.
5x/9 = 20.
5x = 180.
x = 36.
No. of boys = 16.

omg please help me im literally dying
Answer:
(-2,3)
Step-by-step explanation:
Multiply -3x+4y=18 with 2:
-6x+8y=36
Add -6x+8x=36 and 6x+2y=-6
10y=30
y=3
So y=3 we can replace y with 3 on any of these two equations:
6x+6=-6
Move the 6 to the other side:
6x=-12
x=-2
So the solution is
(-2,3)

Answer:
I believe the measurement of angle 5, would be 114.
Step-by-step explanation:
We can solve this by using alternate interior angles. First we must find the other alternate interior angle for angle 5. To do this we take 66 and subtract it from 180. We now find that the angle adjacent to the angle measuring 66 degrees is equal to 114 degrees. Now, the angle we just found the measurements for, is the alternate interior angle for angle 5. Therefore, since they are alternate interior angles, angle 5 is equal to 114 degrees.

✨✨ Easy points for people who are good at finding slope! ✨✨
Considering that all quadrilaterals are squares. When x varies 1 unity, y varies 5 units. So the slope is 5.
Answer:
the answer is D
Step-by-step explanation:
slope=rise÷run
from point A to B 1 right and 5 up, so both are positive
rise is up or down
run is left or right
slope=5÷1=5
so the answer is D
