Solving \frac{6}{x+2}=\frac{3}{4} we get x=6

Step-by-step explanation:

We need to solve \frac{6}{x+2}=\frac{3}{4}

Solving:

Cross multiply both terms:

4*6=3(x+2)\\24=3x+6\\3x=24-6\\3x=18\\x=18/3\\x=6

Verifying the solution:

Putting x=6 in the question given:

\frac{6}{x+2}=\frac{3}{4}

\frac{6}{6+2}=\frac{3}{4}

\frac{6}{8}=\frac{3}{4}

\frac{3}{4}=\frac{3}{4}

Solving \frac{6}{x+2}=\frac{3}{4} we get x=6

Write the equation that passes through the following points:<br><br> (5,0) and (−10,−5)
Vikentia [17]

Answer:

The answer is:

y =  \frac{1}{3} x -  \frac{5}{3}

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

y = mx + b

❃Incase you also forgot, The is what the slope formula is ☟

m = \frac{y_2 - y_1 }{x_2 - x_1}

➊ First: We are going to be solving for the slope.

m = \frac{  - 5 - 0}{ - 10 - 5} = \frac{ - 5}{  - 15} =  \frac{1}{3}

➋Second: We find the y-intercept.

y = mx + b \\ 0 =  \frac{1}{3} (5) + b \\ 0 =  \frac{5}{3}  + b \\ \frac{  -   \frac{5}{3}  =  -  \frac{5}{3 }   \:  \:  \:  \:  \:  \:  \: \: \: \: \: \: }{  -  \frac{5}{3}  = b}

➌Third: Plug in.

y =  \frac{1}{3} x -  \frac{5}{3}

Last summer, Betty earned $4200 by painting houses. She invested
Musya8 [376]

x*(1.035) + (4,200-x)*(1.045) = 4,374.00

1.035x + 4,389.00 -1.045x = 4,374.00

15.00  = .01x

x = 1,500  so x (1,500) invested at 3.5% and  

(4,200 - 1,500) (or 2,700) invested at 4.5%
