For which variable?
solve for y
y=x+30
solve for x
x=y-30
Hope this helps:)
Answer: No its not a function.
Step-by-step explanation: Its not a function because the y coordinate has the same x coordinates. This fails the vertical line test.
Answer:
![x^3+3x^2+2x](https://tex.z-dn.net/?f=x%5E3%2B3x%5E2%2B2x)
Step-by-step explanation:
<u>Definitions</u>
Integer: A whole number that can be positive, negative, or zero.
Consecutive Integers: Integers that follow each other continuously in the order from smallest to largest.
Product: The result of multiplying two of more values together.
Let x be the first integer.
Therefore, to find the consecutive integers, add 1 to each term:
- x
- x + 1
- (x + 1) + 1 = x + 2
Therefore, the product of the first three consecutive integers is:
![\begin{aligned}x(x+1)(x+2) & = (x \cdot x+x \cdot 1)(x+2)\\& = (x^2+x)(x+2)\\ & = x^2 \cdot x+x^2 \cdot 2+x \cdot x+x \cdot 2\\& = x^3+2x^2+x^2+2x\\& = x^3+3x^2+2x\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7Dx%28x%2B1%29%28x%2B2%29%20%26%20%3D%20%28x%20%5Ccdot%20x%2Bx%20%5Ccdot%201%29%28x%2B2%29%5C%5C%26%20%3D%20%28x%5E2%2Bx%29%28x%2B2%29%5C%5C%20%26%20%3D%20x%5E2%20%5Ccdot%20x%2Bx%5E2%20%5Ccdot%202%2Bx%20%5Ccdot%20x%2Bx%20%5Ccdot%202%5C%5C%26%20%3D%20x%5E3%2B2x%5E2%2Bx%5E2%2B2x%5C%5C%26%20%3D%20x%5E3%2B3x%5E2%2B2x%5Cend%7Baligned%7D)
