Answer:
0.9875
PLEASE GIVE ME BRAINIEST! <:)
Step-by-step explanation:
What is 79/80 as a decimal?
To write 79/80 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 79 by 80 what we write down as 79/80 and we get 0.9875
And finally we have:
79/80 as a decimal equals 0.9875
To factor the equation, first make sure the right hand side is equal to 0. Do this by subtracting 25 from both sides of the equation.
The equation becomes,
n^2-8n-9 = 0
Factoring the equation now gives you (n-9)(n+1) = 0.
In order to find the solutions to this equation, find values of 'n' that make the equation equal to 0.
In this case, if n is 9 or -1, we get the answer 0.
Proof: (9-9)(n+1) => (0)(n+1) = 0
or (n-9)(-1+1) => (n-9)(0) = 0.
Hope this made sense! If it didn't, please ask questions!
Answer:
Hello! I just took the test.
Step-by-step explanation:
The answer is S's coordinates are (a+d, c)
and the slope of RS is 0. You can tell because it is a horizontal line and there is no incline, therefore the slope is zero.
Hope this helps!

Answer:
C: Irrational
Explanation:
the reason i chose C because when you add a rational and irrational number together you still get a repeating number which is irrational.
For Example: Take a rational number 5 and Pi
if you ad those together 5+3.1415... you still get a repeating decimal, and repeating decimals are also irrational numbers.
Hope this helps :D
