The first equation is:
d = 2.5 t + 2.2
For the parallel line :
m = 2.5.
It is passing through: t = 0, d = 1
d = m t + b
1 = 2.5 * 0 + b
b = 1
Answer:
A ) d = 2.5 t + 1

x=50
Answer:
$1615.05
Step-by-step explanation:
First the cost. We know that tuition per credit hour is 113.67 and there is a flat fee of 660. This can be represented by 113.67h + 660, where h is equal to the number of credit hours.
Next, the amount paid. There are two constants of 350 and 400 already there. We can represent the remaining amount that needs to be paid by another variable, x.
Now, the cost needs to be equal to the amount you pay. We can replace h with 15 for 15 hours and solve for x.
113.67h + 660 = 350 + 400 + x
113.67(15) + 660 = 350 + 400 + x
1705.05 + 660 = 750 + x
2365.05 = 750 + x
1615.05 = x
Answer:
Step-by-step explanation:
The formula is given as:
We need to solve this formula for v, that means that v to one side and let it be solved in terms of the other variables (E and m). First, we isolate v:
To isolate v, and eliminate the "square", we need to take square roots of both sides, that will give us v in terms of the other variables:
Putting v to left side (convention), we finally have:
