Answer:
6
Step-by-step explanation:
Let's move out the tips first.
88.50-43.50=45
Now let's divide the hour earnings to find his hours!
45/7.50 = 6
So 6 hours!
The quadratic equation for this would be f(x) = 5x^2 - 10x - 120.
In order to find that, we need to start by taking our x intercept values and setting them equal to zero.
x = 6 ----> subtract 6 from both sides
x - 6 = 0
x = -4 ----> add 4 to both sides
x + 4 = 0
Now that we have both of these zero terms, we can multiply them to get a standard form.
f(x) = (x - 6)(x + 4)
And while this will give us the zeros we need, it will no give us the lead coefficient. So we must multiply by the desired lead coefficient.
f(x) = 5(x - 6)(x + 4)
f(x) = 5(x^2 - 6x + 4x - 24)
f(x) = 5(x^2 - 2x - 24)
f(x) = 5x^2 - 10x - 120
Answer:
23+0.05m=88.65
Step-by-step explanation:
0.05m=65.65
m=1,313
i think this is right, I am sorry if it is wrong...
Answer:
21/10 mph
Step-by-step explanation:
When you divide a fraction with another fraction, the number after the division sign gets flipped (meaning that the numerator and denominator switch so 1/2 would be 2/1)
So using that we can solve this:
7/5 / 2/3
7/5 * 3/2
21/10 miles per hour
The answer to this scatter plot question is y=1/3x-9
