X-9=0
x=9
x-8=0
x=8
Thus the answer is x=9, x=8
Answer:
36x^8
Explanation:
Use the rules of exponents
Use substitution
From second equation:-
x = 13 - 5y, Substitute for x in the first eqaution:
(13 - 5y)^2 + y^2 = 13
169 -130y + 25y^2 + y^2 - 13 = 0
26y^2 - 130y + 156 = 0
26(y^2 - 5y + 6) = 0
26(y - 3)(y - 2) = 0
y = 2 , y = 3
From the second equation when y = 2, x = 13 - 5(2) = 3
and when y = 3, x = 13 - 5(3) = -2
So the solution is [3, 2} and {-2, 3}
To find the percentage of a number multiply it by whatever decimal you are using or a fraction that you have to convert into a decimal to find the percent. Example: What is 10% of 25? (.10)(25) = 2.5 so 10% of 25 is 2.5.
Answer:

Step-by-step explanation:
Given data
It costs $35 for a membership
Monthly fee is $15
Let the number of months be x
and the total cost for x months be y
Hence the expression for the cost after x months is given as:
