Answer:
9x
Step-by-step explanation:
(x² + 2x) - (x² - 7x) ← distribute parenthesis
= x² + 2x - x² + 7x ← collect like terms
= 9x
I think it 0.07 but dont count onmy answer
The equation for plane a and plane b is
15+0.25x = 20+0.05x find the x and plug them in the equation i hope that helps
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of years, where x = 0 represent the first year. Let y represent the number of pizzas baked.
In the first year(i.e. at x = 0), 2000 pizza was baked. This can be represented by (0, 2000).
In the second year(i.e. at x = 1), 3000 pizza was baked. This can be represented by (1, 3000).
In the third year(i.e. at x = 2), 4000 pizza was baked. This can be represented by (2, 4000).
Therefore, the relationship between x and y is given by:

Using the points (0, 2000) and (2, 4000):

Move all terms that don't contain x to the right side, and solve.
x = - 3y/2 + 18
