Remark

It is a direct variation.

y = k x

You can solve for k .

y = 208

x = 4

k= ??

y = k * x

208 = k * 4 Divide by 4

208 / 4 = k

k = 52

So the equation becomes

y = 52 x

What is 0.06x-0.18=0.12

MAXImum [283]

Hi there!

To solve this problem, we should simplify.

0.06x - 0.18 = 0.12

First, we should add 0.18 to both sides:

0.06x = 0.12 + 0.18
0.06x = 0.3

Now, we can convert 0.06 into a fraction and multiply both sides of the equation by its receprical to isolate x:

0.06 = 6/100
6/100 × 100/6 = 1
0.3 × 100/6 = 30/6
x = 30/6
x = 15/3
x = 5

So, x is 5.

Hope this helps!

find the slope of the line containing the points (-1,6) and (3,5) put final.answer in slope-intercept form

Ugo [173]

Given the points (-1,6) and (3,5).

The formula to find the slope is

$m=\frac{y_2-y_1_{}}{x_2-x_1}$

Take

$x_1=-1,y_1=6,x_2=3,y_2=5$

Plug the values into the formula and find the slope.

$\begin{gathered} m=\frac{5-6}{3-(-1)} \\ =\frac{-1}{4} \end{gathered}$

The slope-intercept form is y = mx+b.

Plug the value of m.

$y=-\frac{1}{4}x+b$

ThusConsider the point (-1,6). Substitute -1 for x and for y into the equation.

$\begin{gathered} 6=-\frac{1}{4}(-1)+b \\ =\frac{1}{4}+b \\ b=6-\frac{1}{4} \\ =\frac{23}{4} \end{gathered}$

Thus, the equation of the line in slope intercept form is

$y=-\frac{1}{4}x+\frac{23}{4}$
