(x + 1)(x + 8)
Step-by-step explanation:
I graphed the equation on the graph below to find the x values.
Answer:
C
Step-by-step explanation:
Given
2x² + x - 1 = 2 ( subtract 2 from both sides )
2x² + x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 3 = - 6 and sum = + 1
The factors are - 2 and + 3
Use these factors to split the x- term
2x² - 2x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x + 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -

The number of calories in 1 burgers is 180
The calories in the soda is 280
Answer:
60 + 2.5n ≥ 150
2.5n ≥ 90
n ≥ 36 She must clean 90 tables to earn at least $150.
Step-by-step explanation:
She earns $2.50 for each table she cleans so n represents the number of tables she cleans. You add that to $60. At least must mean that the inequality has to be equal to or bigger than 60 + 2.5n.
Now we just have to solve, which I do for you above in the 'Answer' section.
I hope this helps you!! ^-^
