Start off with the exponents
2-5=-3
distribut the exponents then multiply each by 3
y=3(x+2)^-3
>>>>y=3x^-3+.375

Answer:
original number is 13
Step-by-step explanation:
let n be the number then twice the number is 2n , so
2n - 16 = 10 ( add 16 to both sides )
2n = 26 ( divide both sides by 2 )
n = 13
Depending on if you're solving for X or Y:
X less than or equal to 4y/3 -5
Y greater than or equal to 3x/4+15/4
First, you would add 9x to both sides so that you get:
x^2 + 9x + 20 = 0.
Then, you want to factor. You want coefficients of x that add to 9 and have the constants add to 20:
(x + 5) * (x + 4) = 0
The answer is (C).
Answer:
It is not possible to solve the equation y = 4x + 3. This is merely a relation between two variables x and y. The variable y is 3 greater than 4 times the variable x.
