Answer:

D = 9.85 units

Step-by-step explanation:

A (1,7) and B(10,3)

Using Distance Formula to find the length

=> Distance Formula = $\sqrt{(x2-x1)^2+(y2-y1)^2}$

=> D = $\sqrt{(10-1)^2+(3-7)^2}$

=> D = $\sqrt{(9)^2+(-4)^2}$

=> D = $\sqrt{81+16}$

=> D = $\sqrt{97}$

=> D = 9.85 units (Upto 3 sfs)

Find the slope of the line that passes through (-2, 8) and (-10, 14)

vesna_86 [32]

Hello!

To find the slope we divide the difference of the y-values by the difference of the x-values as shown below.

$\frac{14-8}{-10+2} = -\frac{6}{8} = -\frac{3}{4}$

The slope of our line is -3/4.

I hope this helps!

How many solutions are there to the equation below? hs<br> 6x + 30 + 4x = 10(x + 3)

solmaris [256]

Answer: Infinity solution

Step-by-step explanation:

6x + 30 + 4x = 10x + 30

10(x + 3) = 10x + 30

10x + 30 = 10x + 30

What is the equation of the line that is parallel to y =1/5x+4

atroni [7]

Answer:

y=(1/5)x-5

Step-by-step explanation:

The given equation is

y=(1/5)x+4

This is of the form

y=mx+b

which is called the slope-intercept form because

m is the slope

b is the y intercept.

In this case,

m=1/5

b=4

you can see from the chart that this matches the red line.

If two lines are parallel, they must have the same slope. So we know that the slope of the desired line is 1/5. So, now we know that

y=(1/5)x+b

Since the line must go through the point (5,-4), we have

-4=(1/5)(5)+b

-4=1+b

b=-5

So, the desired line is

y=(1/5)x-5
