Alright, so the money you make is automatically -1500 for the tools, so it's -1500. Next, the materials cost 200 dollars for each scooter, s, so we have -1500-200s. After that, we have 300 dollars for the sale of each scooter, so we have -1500-200s+300s. Adding -200 and 300 together, we have -1500+100s. To make a profit, that means 100s -1500 > 0. Dividing by 100, we have
s -15 >0 and s>15, so if you sold 16 scooters you'd make a profit. That profit would be 100*16-1500=1600-1500=100 dollars
7(2x+5)=4x-9-x
14x+35=3x-9
11x = -44
x = -4
7(2*-4+5)=4*-4-9--4
7(-3)=-21
-21=-21. so it checks out and x = -4
Answer:
8x
Step-by-step explanation:
x · 8
8x
Answer:
6.4 miles
Step-by-step explanation:
5^2 + 4^2 = d^2
25 + 16 = d^2 = 41
d = 6.40 miles
Answer:
The answer to your question is the third choice.
Step-by-step explanation:
The axis of symmetry is the dotted red line which is located in x = 1/2
The Vertex is the lowest point of the parabola which is (1/2, -1)
The equation of the function is:
(x - h)² = 4p(y - k)
-Substitution
(x - 1/2)² = 4p(y + 1)
-We can not know the value of p
x² - x + 1/4 = y + 1
Discarding choices, there are two possible answer, the second and the third choices, but because of the Vertex (0.5, -1), i think the right answer is the third choice.
