Answer:
$1400
Step-by-step explanation:
Assuming that you would pay off the debt now and not wait any longer than to calculate how much more money you need you simply need to subtract the $1000 that you have from the total which is $2400.
$2400 - $1000 = $1400
Finally, we can see that you need an extra $1400 in order to finish paying off the debt. Unless you wait more time and the overall debt owed rises some more.
The answer to your question is x= 2
The numeric values for the function are given as follows:
a) f(-5) = 14.
b) f(0) = 10.
c) f(5/2) = 8.
d) f(5a) = -4a + 10.
e) f(5a - 15) = -4a + 22.
<h3>How to find the numeric value of a function?</h3>
To find the numeric value of a function, we replace each instance of the variable by the desired value.
For this problem, the function is given by:
f(x) = -0.8x + 10.
Hence the numeric values are given as follows:
- f(-5) = -0.8(-5) + 10 = 14.
- f(0) = -0.8(0) + 10 = 10.
- f(5/2) = f(2.5) = -0.8(2.5) + 10 = 8.
- f(5a) = -0.8(5a) + 10 = -4a + 10.
- f(5a - 15) = -0.8(5a - 15) + 10 = -4a + 22.
