Answer: 315 miles
Step-by-step explanation:
let onward speed = x mph, then distance = 7x
return speed = (x+18) mph, (same) distance = 5(x+18)
equating the two,
7x = 5(x+18)
2x = 90 ==> x = 45 mph
so distance = 7*45 = 315 miles
C. (1,-4)
Vertex is the point where the parabola begins. The vertex is one unit to the right on the x axis and 4 units down on the y axis which gives you the coordinate (1,-4)

Hello!</h2>
The answer is:
Tito needs a total of $6500 in sales if he want to receive $710 a week.
The equation is:
<h2>
Why?</h2>
From the statement we know that his salary is $450 plus a 4% commission on the total amount of all sales he makes.
So, we can write the following equation to determine the total sales in a week if he wants to make a total of $710.
Remember, if we are working with percents, we need to change it to real numbers in order to perform the calculations, we can do it by dividing the percent value into 100.
We have:
Now, if he wants to make a total of $710, we have:
We have that Tito needs a total of $6500 in sales if he want to receive $710 a week.
Have a nice day!
Factor all 3 numbers
14 = 2 * 7
15 = 3 * 5
21 = 3 * 7
There are no common factors in all 3 numbers
Answer No GCF.
Though i guess you could say 1 is the GCF.
Replace the x values in the equation, then solve:
[(-2)^2+4]/[(-2)^2-2(-2)-48=
(4+4)/4+4-48=
8/8-48=
8/-40=
-1/5
