2/9 divided by 7/9<br> could you help me with this please i really need help please.
never [62]

Answer: 2/9 divided by 7/9 = 2/7

Step-by-step explanation:

1. Write out the problem on a piece of paper.

2. Change the second fraction, which is 7/9, into a reciprocal fraction (means flipping the 7 and 9 around). Now, our equation has the fraction 9/7 in it.

3. Change the division symbol to a multiplication symbol. Your equation should be 2/9 x 9/7.

4. Solve the equation. You should get the answer of 18/63 without simplification.

5. Simplify. 18/63 = 2/7

Conclusion: 2/7 is the correct answer.

For f(x)=x^2,sketch the graph of g(x)=f(-5x+10)
DiKsa [7]

The graph of g(x) = f(-5x+10) is given in the figure.

<h3>What is a graph?</h3>

A diagram showing the relation between two variable quantities,each measured along one of a pair of axes at right angles.

It is given that f(x) = x^2

and g(x ) = f(-5x+10)

Now putting the value of f(x) in g(x) we get,

g(x)  = f(-5x+10)  = (-5x+10)^2

So, g(x) = (-5x+10)^2

now, making the table for g(x),

<u><em>x </em></u><u>g(x)</u>

0 100

1 81

2 0

3 25

4 100

5 225

Hence,the graph of g(x) = f(-5x+10) is given in the figure.

B. How was the original $20,000 investment split between the two interest rates?
Roman55 [17]

Answer:

t + f = 2000

let  represent the amount invested at three percent; let f represent the amount invested at five percent. The total of these amounts is $20,000. The total of the interest earned by each amount is $800. Of course the interest earned is the amount multiplied by the interest rate.
