Answer:
The negative valued x-intercept is (-6, 0)
Step-by-step explanation:
<u>Step 1: Factor</u>
3x^2 + 13x - 30
(3x - 5)(x + 6)
<u>Step 2: Solve for x</u>
3x - 5 + 5 = 0 + 5 and x + 6 - 6 = 0 - 6
3x / 3 = 5 / 3 and x = -6
x = 5/3 and x = -6
Answer: The negative valued x-intercept is (-6, 0)
60 + 4*60= full price
$300=full price
I got 4*60 in the equation because 80% is 4 time 20%
The full price of the lawn mower is $300
I don't think you need to. Only the ones Like "Science 101", etc.
