Answer:
he will owe $1,047 in total and $97.37 in interest
The value of a is 
Step-by-step explanation:
<u>1. Determine the other solution of x</u>
If one value is 5 +
then the other value is 5 - 
<u>2. Use reverse technique to find the equation</u>
(5 +
) (5 -
) = 0
25 -
+
-
= 0
-
+ 25 = 0
<u>3. The equation is</u> -
+ 25 = 0
<u>4. Find the value of a</u>
a is the number with the variable
therefore it is -

Substitute y = 15x to the equation y = 25 + 12.5x:
15x = 25 + 12.5x <em>subtract 12.5x from both sides</em>
2.5x = 25 <em>divide both sides by 2.5</em>
x = 10
Substitute the value of x to the equation y = 15x:
y = (15)(10)
y = 150
<h3>
Answer: x = 10 and y = 150</h3>
Answer:
The diver will hit the water at 1.5 seconds
Step-by-step explanation:
Given

Required (Missing from the question)
When will the diver hit the water?
To do this, we simply solve for t
When the diver hits the water, the height is 0 (at that point)
So, substitute 0 for h in 

Divide both sides by -16




Split
or 
Solve for t
or 
But time (t) can not be negative.
So:

Hence, the diver will hit the water at 1.5 seconds
