Answer:
2x^2 + 3x + 2
Step-by-step explanation:
Like terms must have exactly the same variables and exponents on the variables.
2x^2 is not a like term to any other term, so it cannot be combined.
3x is not a like term to any other term, so it cannot be combined.
3 and -1 have no variable, so they are like terms and can be combined.
2x^2 + 3 + 3x - 1 =
= 2x^2 + 3x + 3 - 1
= 2x^2 + 3x + 2
Answer:
y=7x
Step-by-step explanation:
Take two points from the line and plug them into y2-y1/x2-x1. In this case, I chose (6,42) and (7,49). This will make the equation 49-42/7-6. This is equal to 7/1 or 7. Therefore, the equation is equal to y=7x.
