hope this helps
The value of c so that the function f ( c ) = 20 is when c = 9
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is given by
f ( x ) = 3x - 7
Now , substituting the value of f ( x ) = 20 , we get
when x = c
f ( c ) = 3c - 7
The value of the equation f ( c ) = 20
Substituting the value in the equation , we get
3c - 7 = 20
On simplifying the equation , we get
Adding 7 on both sides of the equation , we get
3c = 27
Divide by 3 on both sides of the equation , we get
c = 9
Therefore , the value of the variable c = 9
Hence , The value of c so that the function f ( c ) = 20 is when c = 9

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $5660 and his stock in Company B was worth $2500. The stock in Company A has increased 5% since last year and the stock in Company B has increased 9%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
The total percentage increase in the investor's stock account will be 8.6%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The amount he earned from company A and company B is given as,
Earned = $5660 x 0.05 + $2500 x 0.09
Earned = $283 + $225
Earned = $508
Then the total percentage increase in the investor's stock account is given as,
P = [(508) / (5660 + 2500)] x 100
P = (508 / 5910) x 100
P = 0.086 x 100
P = 8.6%
The total percentage increase in the investor's stock account will be 8.6%.

choose yes or no to tell if the fraction 2/9 will make each equation true
81 x =18
900 x = 200
72 x =16
450x = 100
Answer:
yes
Step-by-step explanation:
to see if 2/9 will make each equation true, you replace 'x' with 2/9, so let us do just that-
81*2/9=18
900*2/9=200
72*2/9=16
72*2/9=16
450*2/9=100
now, seeing as how every answer we've gotten matches the answers of the algebraic equations, the answer is yes 2/9 does make each equation true
good luck :)
