Find the function h(x) = f(x) + g(x) if f(x) = 4^x + 2 and g(x) = x - 4.
h( x) = 4 x + 1 -2
h( x) = 4 x + x + 6
h( x) = 4 x - 4
h( x) = 4 x + x - 2
Answer:
h( x) = 4^x + x - 2
Step-by-step explanation:
h(x)=f(x)+g(x)=4^x+2+x-4=4^x+x-2

The sum of b and its reciprocal
Answer:
(b^2+1)/b
Step-by-step explanation:
The reciprocal of b is written as 1/b
The sum of b and 1/b is expressed as;
b + 1/b
Sind the LCM
= b(b)+1/b
= (b^2+1)/b
Hence the sum of b and its reciprocal is (b^2+1)/b

Question 3
Simplify a4 x b x a4 x b
15/3 = 45/x
solve for x
Answer:
15/3=45/x
We move all terms to the left:
15/3-(45/x)=0
Domain of the equation: x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
-(+45/x)+15/3=0
We add all the numbers together, and all the variables
-(+45/x)+5=0
We get rid of parentheses
-45/x+5=0
We multiply all the terms by the denominator
5*x-45=0
We add all the numbers together, and all the variables
5x-45=0
We move all terms containing x to the left, all other terms to the right
5x=45
x=45/5
x=9

how can you tell just by looking at the numerator and denominator of a fraction if it is closer to 0 or 1? Give some examples in your explanation.
Help
If denominator of the fraction is greater than numerator then it is closer to 0 or 1.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;
The fraction is closer to 0 or 1.
Now,
Let a fraction as;
⇒ 4 / 7
Then, It is equivalent to,
⇒ 4 / 7 = 0.57
Which is closer to 0 or 1.
So, We can conclude that;
⇒ If denominator of the fraction is greater than numerator then it is closer to 0 or 1.

Write an equation for the circle
Given:
The graph of a circle.
To find:
The equation of the given circle.
Solution:
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
Where, (h,k) is vertex and r is the radius.
From the given graph it is clear that the radius of the circle is 4 units and the center of the circle is (-2,2).
Putting [tex]h=-2, k=2[/tex] and [tex]r=4[/tex] in (i), we get
[tex](x-(-2))^2+(y-(2))^2=(4)^2[/tex]
[tex](x+2)^2+(y-2)^2=16[/tex]
Therefore, the equation of the circle is [tex](x+2)^2+(y-2)^2=16[/tex].

Lucius sells jellyfish jam part-time. He is paid a monthly commission. He receives 30% of his first $900 in sales and 25% of the rest of his sales. Last month he sold $2,600 worth of jam. How much commission did he earn last month?
Answer:
695
Step-by-step explanation:
First I would septate the 900 from the 2600
2600-900=1700
Then I'll take both %s and turn them to decimal 25%-0.25 30%-0.30
I take the 900 times the 0.30 and the 0.25 times 1700
900x0.30=270
1700x0.25=425
then add them both together
270+425=695

Beth and Bryce sign on a $205,000 mortgage at a 5% annual interest rate for 30 years. This results in a monthly payment of $1100.48. If only the minimum payment is made in month one, how much of the first payment goes toward reducing her balance?
Answer: $246.31
Step-by-step explanation:
The monthly payment of $1,100.48 is going to be divided into interest and principal repayment which is the one that reduces her balance.
The interest payment is based on the interest rate which is 5%.
Monthly interest is:
= 205,000 * 5% * 1/12 months because it is monthly
= $854.17
The amount that goes towards reducing her balance is:
= Monthly payment - Interest payment
= 1,100.48 - 854.17
= $246.31
