Answer:

first is the chart so for the time row its 4, 8, 12, 16, 20 & distance is 3, 6, 9, 12, 15

I added the complete graph down below, basically what i did wasplot the points from the chart so (4,3), (8,6), (12,9), (16, 12), and (20,15)

so for example for (4,3) you would first find 4 on the x-axis or the time line and then find 3 on the y-axis and so on let me know if you can see the picture:)

Given:

The equation of a line is:

$y=-\dfrac{5}{7}x+2$

A line passes through the point (-5,-3) and perpendicular to the given line.

To find:

The equation of the line.

Solution:

Slope intercept form of a line is:

$y=mx+b$ ...(i)

Where, m is the slope and b is the y-intercept.

We have,

$y=-\dfrac{5}{7}x+2$ ...(ii)

On comparing (i) and (ii), we get

$m=-\dfrac{5}{7}$

We know that the product of slopes of two perpendicular lines is always -1.

$m_1\times m_2=-1$

$-\dfrac{5}{7}\times m_2=-1$

$m_2=\dfrac{7}{5}$

Slope of the required line is $\dfrac{7}{5}$ and it passes through the point (-5,-3). So, the equation of the line is:

$y-y_1=m_2(x-x_1)$

$y-(-3)=\dfrac{7}{5}(x-(-5))$

$y+3=\dfrac{7}{5}(x+5)$

Using distributive property, we get

$y+3=\dfrac{7}{5}(x)+\dfrac{7}{5}(5)$

$y+3=\dfrac{7}{5}x+7$

$y=\dfrac{7}{5}x+7-3$

$y=\dfrac{7}{5}x+4$

Therefore, the equation of the line is $y=\dfrac{7}{5}x+4$ . Hence, option A is correct.

Break the numbers 0-9 into 3 groups. Each group needs to equal the same number when added! Write out the groupsand the sum of ea

Burka [1]

we must do the following:

select the major, the minor and the half and add, like this:

$9+0+5+1=15$

therefore:

$7+6+2=15$

also:

$\begin{gathered} 8+4+3=15 \\ \end{gathered}$

the groups are:

(9,0,1,5); (7,6,2); (8,4,3)
