Answer:
-35
Step-by-step explanation:
Answer:
The equation is true.
Step-by-step explanation:
First you divide both sides of the equation by 3. This leaves you with 9-2=7 (notice I rewrote 9+(-2) to 9-2, this is because they mean the same thing one is just easier to look at). Then you add 2 to both sides. This cancels the 2 on the left side and makes the rights side a nine. Since both sides leave you with nine this proves are equal, making it a true equation.
Answer:
<u>maximum of 2 bicycle</u>
Step-by-step explanation:
Given the average cost per bicycle modeled by the equation
C(x) = 0.5x^2-1.5x+4.83
C(x) is in hundreds of dollars
x is number of bicycle
The number of bicycle that will minimize the cost occurs when dC/dx = 0
dC/dx = 2(0.5)x - 1.5
dC/dx = x - 1.5
Since dC/dx = 0
0 = x - 1.5
x = 0+1.5x = 1.5
Hence the shop should buy <u>maximum of 2 bicycle</u> to minimize the cost
Answer:
Step-by-step explanation:
-x - 1 = x + 3
-2x - 1 = 3
-2x = 4
x = -2
y = -2 + 3
y = 1
(-2, 1)
Answer:
420 miles
Step-by-step explanation:
Distance traveled per hour = 55 miles
Distance traveled in 6 hours = 55 * 6 = 330 miles
Distance of the trip = 330 + 90 = 420 miles
