Answer:
B
Step-by-step explanation:
4x^2+16x+14=0
I just transfered the given equation to the other side..that must be in a standard form where ax^2+bx+c=0
For this case, the first thing we must do is define variables:
x: rolls of wrapping paper in one week
We now write the equation that models the profit of the band.
We have then:
P (x) = (3.50 - 2) x - 4
P (x) = 1.50x - 4
Answer:
An equation to model the amount of profit, P, the band makes from x rolls of wrapping paper in one week is:
P (x) = 1.50x - 4
Answer: 7.5×10^-4
Step-by-step explanation:
0.00075
Scientific notation means standard form
There are 3 zeros in front of the 7
So take the decimal to the back of 7
You have
7.5
Since you are counting backward, it will be negative
So we have
7.5×10^-4
Percent means per hundred. So 3% is like 3/100 or as a decimal .03, with 3 in the hundredths place.
