Answer:

(A) $7x^2+5x$

Step-by-step explanation:

Given:The given expression is:

$(9x^2+8x)-(2x^2+3x)$

To find: The difference of the two polynomials.

Solution: The given expression is:

$(9x^2+8x)-(2x^2+3x)$

Upon solving the above equation, we get

$9x^2+8x-2x^2-3x$

Combining the like terms and then solving,

$9x^2-2x^2+8x-3x$

$7x^2+5x$

which is the required difference.

Hence, option A is correct.

Twice as many students are in the chess club as in the fencing club.The number of students in the fencing club is one fifth the

jekas [21]

Answer:

28 students

Step-by-step explanation:

Let number of students in cooking club = x

Number of students in fencing club = 1/5 x

Number of students in chess club = 2(1/5)x

Since, There are 42 more students in the cooking club than in the chess club

Then ;

Number of students in chess club = Number of students in cooking club - 42

2(1/5)x = x - 42

(2/5)x - x = - 42

-0.6x = - 42

x = 42 / 0.6

x = 70

Hence, number of students in chess club :

(2/5) * 70 = 28

How does the graph of g(x)= 1/x-5+2 compared to the graph of the parent function f(x)=1/x?

Finger [1]

Answer: The graph is shifted to the right by 5 units and shifted up from the parent function.

Step-by-step explanation:

1. By definition, a parent function is the simplest form of a function.

2. You have the following parent function given in the problem:

$f(x)=\frac{1}{x}$

2. The function g(x) is obtained from the function f(x)

$g(x)=\frac{1}{x-5}+2$

Where the subtraction of 5 indicates the horizotanl shift to the left and the addition of 2 indicates the vertical shift up.

3. Therefore, keeping the information above on mind, you can conclude that the answer is: the graph is shifted to the right by 5 units and shifted up from the parent function.
