Answer:
x = 3.391
Step-by-step explanation:
first you calculate.
7.9% - 0.25 = 3.22 + x
divide the numbers
- 0.25 = 3.22 + x
calculate again.
0.079 - 0.25 = 3.22 + x
move the terms
<u>-0.171</u> = <u>3.22 + x</u>
add the numbers
<u>-x = 3.22 + 0.171</u>
then change the signs
<u>-x = 3.391</u>
Final ans : <u>x = -3.391</u>
or some alternate answer's
x = - , x = -3
- + 6
divide each term on the numerator by 7b
= - 7 / 7b + 42
/ 7b
= - + 6
Answer:
The possible values are a = -2.5 or a = 4.5.
Step-by-step explanation:
Composite function:
The composite function of f(x) and g(x) is given by:
In this case:
So
Value of a so that the y-intercept of the graph of the composite function (fog)(x) is (0, 25).
This means that when . So
Solving a quadratic equation, by Bhaskara:
The possible values are a = -2.5 or a = 4.5.
