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.
Answer:
see below
Step-by-step explanation:
65 - 32 = 13

Answer:
<h2>37/9</h2>
Step-by-step explanation:
<h3>we have</h3>
<h3>3.77777... :- is a repeating decimal</h3>
<h3>Let</h3>
<h3>x = 3.7...</h3>
<h3>so</h3>
<h3>10x =37.7...</h3>
<h3>10x - x = 37.7... -3.7...</h3>
<h3>9x=34</h3>
<h3>x= 34/9</h3>
<h3>convert to mixed number</h3>
<h3>34/9=(27/9)+(7/9)=3+(7/9) =37/9</h3>
<h3> I hope this may help you.</h3>
