Choose the best definition for the following phrase: combining like terms

1 answer:

3 0

I'm assuming you are talking about polynomials.

For example, I have x^2 + 2x + 1, and I want to add 2x^2 + x + 2

Then the like terms here are:

x^2 and 2x^2, 2x and x, 1 and 2, they are quadratic, linear and constant, respectively.

Ally has 4 times as many pencils as Anna Claire. They have 30 pencils in all. How many pencils does Ally have?

dexar [7]

T = 30

A = 4c

A + c = T

Anna Claire has 6 pencils. Times 4 makes Ally's pencil count. 4 * 6 = 24

24 + 6 = 30. So, you answer is: Ally has 24 pencils.

Let g(x)=9x−10 and evaluate g(x+h)−g(x)/h

castortr0y [4]

Answer:

$\frac{g(x+h)-g(x)}{h}=9$

Step-by-step explanation:

we have

$g(x)=9x-10$

To find out g(x+h) substitute the variable x by the variable (x+h) in the function g(x)

$g(x+h)=9(x+h)-10$

$g(x+h)=9x+9h-10$

Evaluate

$\frac{g(x+h)-g(x)}{h}$

we have

$g(x+h)=9x+9h-10$

$g(x)=9x-10$

substitute in the expression

$\frac{9x+9h-10-(9x-10)}{h}$

$\frac{9x+9h-10-9x+10)}{h}$

$\frac{9h}{h}$

$9$

therefore

$\frac{g(x+h)-g(x)}{h}=9$
