Top answer is -4 because when you divide by a negative your answer will come out negative and bottom answer is 6 because when you multiply two negatives it turns into a positive
Answer:
29/7
Step-by-step explanation:
10-5x=3(x-4)-(x+7)
10-5x=3x-12-x-7
10-5x=3x-x-12-7
10-5x=2x-19
10-5x-2x=-19
10-7x=-19
7x=10-(-19)
7x=10+19
7x=29
x=29/7
Using a linear function, we have that:
- The rule is P(x) = 0.5x - 75.
- The total profit after selling 0 ribbons is of -$0.75.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For this problem, when x increases by 10, the profit increases by 5, hence the slope is:
m = 5/10 = 0.5.
Then:
P(x) = 0.5x + b.
When x = 10, P(x) = -70, hence:
-70 = 0.5(10) + b
b = -75.
Hence:
- The rule is P(x) = 0.5x - 75.
- The total profit after selling 0 ribbons is of -$0.75.

Answer:
Step-by-step explanation:
Potential energy=stored energy so say when the roller coaster stops somewhere they are storing energy.
In then when they just go down there would now be using kinetic energy.
Hope this helps have a great afternoon:)
