Answer:
x=8
Step-by-step explanation:
44-20=24
24/4=8
The answer is 7x - 9 = 75. Please mark me brainiest
8 - 1 = 7
7 - 9 = -2
7 divided by -2 is -3.5
The slope is -3.5 now we need to find the y intercept.
To find the y intercept do -3.5 times 7 and you get -24.5.
Next do 8- -24.5 and you get 32.5 which is the y intercept.
The equation would be y = -3.5x + 32.5
Answer:

Step-by-step explanation:
step 1
Find the slope of the line
we know that
If two lines are parallel, then their slopes are the same
so
The slope of the given line is 
therefore
The slope of the line parallel to the given line is 
step 2
Find the equation of the line in point slope form

we have


substitute

Answer:
Step-by-step explanation:
Given that a referral code is 2 letters (A-Z, no lowercases) followed by 4 digits (0-9), or it is 2 digits (0-9) followed by four letters (A-Z, no lowercases).
Digits are not allowed to repeat but letters can repeat.
Thus we find that 2 letters can be selected in

Since for numbers repitition is not allowed, 4 digits can be arranged in 9P4 ways
= 9*8*7*6
Total no of ways for I type=
For II type numbers are 2 and letters are 4.
So no of ways = 
total referral codes possible =
![26^2*9*8*7*6+26^4 *9*8\\= 26^2 (9)(8) [42+676]\\= 34946496](https://tex.z-dn.net/?f=26%5E2%2A9%2A8%2A7%2A6%2B26%5E4%20%2A9%2A8%5C%5C%3D%2026%5E2%20%289%29%288%29%20%5B42%2B676%5D%5C%5C%3D%2034946496)
