Answer:

$y=\frac{3}{2}x-5$

Step-by-step explanation:

There are a couple of ways to solve this, depending on what you already know.

Point-Slope Form

$y-y_1=m(x-x_1)$ where m is the slope and $(x_1, y_1)$ is a point on the line.

First, calculate the slope using the two given points $(x_1, y_1), (x_2, y_2)$ .

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{1-(-2)}{4-2}=\frac{3}{2}$ .

Fill in the point-slope pattern

$y-(-2)=\frac{3}{2}(x-2) \\ y+2=\frac{3}{2}x-3 \\ y=\frac{3}{2}x-5$

There's the equation in slope-intercept form ( $y=mx+b$ ).

Slope-Intercept Form

Use $y=mx+b$ directly.

Find the slope just like the above, so $m=\frac{3}{2}$ .

Now, plug one of the points (either one!) together with m into

$y=mx+b\\-2=\frac{3}{2}(2)+b \\ -2=3+b \\ b=-5$

Now you know the value of b, so the equation for the line is

$y=\frac{3}{2}x-5$

"Then I will need an average quality score of 3.28 to meet 85.28 goal."

Step-by-step explanation:

current average quality score = 82
improvement on average quality score = 4% of 82

⇒ (4/100) $\times$ 82

⇒ 82/25

⇒ 3.28

The improved average quality score = 82+3.28 = 85.28

The employee needs an average quality score of 3.28 to meet the goal of 85.28

Josh can split a truckload of logs in 8 hours, but working with his dad, they can get it done in 3 hours. How long would it take

grin007 [14]

Answer: 4.8 hrs

Step-by-step explanation:

Josh: $\frac{1}{8}$

Dad: $\frac{1}{x}$

Together: $\frac{1}{3}$

Josh + Dad = Together

$\frac{1}{8}$ + $\frac{1}{x}$ = $\frac{1}{3}$

$\frac{1}{8}*(24x)$ + $\frac{1}{x}*(24x)$ = $\frac{1}{3}$ (24x)

3x + 24 = 8x

-3x -3x

24 = 5x
