Answer:
y = 4x +5
Slope is 4
Intercept is 5
Step-by-step explanation:
Using, y1= 1 and x1= -1
And, y2 = 13, x2 = 2
![\frac{y2 - y1}{x2 - x1} = \frac{y - y1}{x - x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20%20%3D%20%20%5Cfrac%7By%20-%20y1%7D%7Bx%20-%20x1%7D%20)
![\frac{13 - 1}{2 - ( - 1)} = \frac{y - 1}{x - ( - 1)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B13%20-%201%7D%7B2%20-%20%28%20-%201%29%7D%20%20%3D%20%20%5Cfrac%7By%20-%201%7D%7Bx%20-%20%28%20-%201%29%7D%20)
![\frac{12}{3} = \frac{y - 1}{x + 1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%7D%7B3%7D%20%20%3D%20%20%5Cfrac%7By%20-%201%7D%7Bx%20%20%2B%201%7D%20)
![4 = \frac{y - 1}{x + 1}](https://tex.z-dn.net/?f=4%20%3D%20%20%5Cfrac%7By%20-%201%7D%7Bx%20%2B%201%7D%20)
![y - 1 = 4(x + 1)](https://tex.z-dn.net/?f=y%20-%201%20%3D%204%28x%20%2B%201%29)
y-1 = 4x +4
y = 4x +4 +1 = 4x +5
The number of boxes renita and Vanessa has unpacked each is 6 and 9 boxes respectively.
<h3>Equation</h3>
- Number of boxes renita has unpacked = x
- Number of boxes Vanessa has unpacked = 2x - 3
- Total boxes both unpacked = 15
x + (2x - 3) = 15
x + 2x - 3 = 15
3x = 15 + 3
3x = 18
x = 18/3
x = 6
Therefore,
Number of boxes renita has unpacked = x
= 6 boxes
Number of boxes Vanessa has unpacked = 2x - 3
= 2(6) - 3
= 12 - 3
= 9 boxes

Answer:
2x < 600 or x < 300
Step-by-step explanation:
x = Johnny's current amount of records.
he result of adding two polynomials will always be another polynomial. A polynomial is an algebraic expression made up of the sum of monomials, which are products of numbers (coefficients) and variables in positive integer exponents.
