Answer:

x=3 y=0

Step-by-step explanation:

This is called system of innequalities

we know y= 3-x and we substitute that into 2x+y=6 and we get

2x+3-x=6 we solve and get x=3

then we substitute x into the first equation and we get y=3-3 and get 0

x=3 y=0

For which rational expression is 8 an excluded value ? check all that apply
denis23 [38]

<u>Answer:</u>

The correct answer options are C. \frac{x^2+5}{x-8} and D. \frac{x^2-x-56}{x^2-64}.

<u>Step-by-step explanation:</u>

The values which make the denominator equal to zero are called the excluded values.

Here, we can substitute 8 for x and check if it makes the denominator 0.

\frac{x-8}{x+8} = \frac{8-8}{8+8} =\frac{0}{16} =0

\frac{x-2}{x^2-4} = \frac{8-2}{8^2-4} =\frac{6}{60} =\frac{1}{10}

\frac{x^2+5}{x-8} = \frac{8^2+5}{8-8} =\frac{69}{0}

\frac{x^2-x-56}{x^2-64} = \frac{8^2-8-56}{8^2-64} = \frac{0}{0} =0

\frac{8x^2-2}{x^2-16} = \frac{8(8)^2-2}{8^2-16} =\frac{510}{48}

Degrees Celsius and degrees Fahrenheit are related by C=5/9(F-32).What is F in terms of C?
valina [46]

We are given: Degrees Celsius and degrees Fahrenheit are related by formula

C=\frac{5}{9} (F-32)

To find : Solve formula for F in terms of C.

Solution: We have , C=\frac{5}{9} (F-32)

First we need to get rid 9 from right denominator.

In order to get rid 9 from right denominator, we need to multiply equation both sides by 9.

9*C=9*\frac{5}{9} (F-32)

9C = 5 (F-32).

Distributing 5 on right side over (F-32), we get 5*F - 5*32 = 5F - 160.

9C = 5F - 160.

Adding 160 on both sides,

9C+160 = 5F - 160+160.

9C+160 =5F

Dividing both sides by 5, we get

(9C+160)/5 =5F/5.

\frac{9C+160}{5}=F

Splitting fraction 1/5, we get

F= \frac{1}{5} (9C+160).
