Hope that helped
Sorry if it’s wrong
There number rounds to 3000 so divide that by 11 and round up your answer
have a good day!!
Answer:
Step-by-step explanation:
The discriminant comes from the quadratic formula. We use the discriminant to determine, before factoring, what types of solutions we can expect when we do factor. In the quadratic formula, the discriminant is under a square root sign. If the number under a square root sign is negative (meaning the discriminant is negative), we will not have real number solutions because you can't have a negative number under a square root. So a is your choice.
Answer: -3, write the division as a fraction, multiply both sides by 2, move constants to the right, then you're left with x=6-9 which is -3
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.
