Answer:

3x+9

Step-by-step explanation:

Remember that like terms can combine. 7x and -4x are like terms, and they combine to get 3x. 12 and -3 are like terms, and they combine to get 9. Therefore, the simplified expression is 3x+9.

R 2x-6+3=6x-5 please help
frozen [14]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

2x - 6 + 3 = 6x - 5

2x - 3 = 6x - 5

6x - 5 = 2x - 3

Add sides 5

6x - 5 + 5 = 2x - 3 + 5

6x = 2x + 2

Subtract sides 2x

- 2x + 6x =  - 2x + 2x + 2

4x = 2

Divide sides by 4

\frac{4x}{4}  =  \frac{2}{4}  \\

x =  \frac{1}{2}  \\

_________________________________

CHECK :

2( \frac{1}{2} ) - 3 = 6( \frac{1}{2} ) - 5 \\

1 - 3 = 3 - 5

- 2 =  - 2

Thus the solution is correct....

If f(x)= 3-2 and g(x)=1/x+5 what is the vue of (f/g) (8)
Lena [83]

Answer:

The value of (f/g) (8) = -169

Step-by-step explanation:

<u>Step 1: explaining the question</u>

The quotient (f/g) is not defined at values of x ⇒  both the functions must be defined at a point for the combination to be defined.

⇒(f/g)(x) =(f(x)) / (g(x))

If f(x)= 3-2 and g(x)=1/x+5

⇒then according to the preceding formula: (f/g)(x) =(f(x)) / (g(x))

⇒(f/g)(8) = f(8) / g(8)

to solve this we have to find the value of both f(8) and g(8)

<u>Step 2: find value of f(8) and g(8)</u>

⇒ we know that f(x) = 3-2x and we know dat f(x) = f(8)

⇒ f(8) = 3-2(8)

f(8) = 3-16 = -13

⇒we know that g(x) = 1/x+5  and g(x) = g(8)

⇒ g(8) = 1/8+5

g(8) =1/13

These 2 equations we will insert in the following : ⇒(f/g)(8) = f(8) / g(8)

⇒ f/g (8) = -13 / (1/13) = -13 * 13/1 = -169

The value of (f/g) (8) = -169
