Which points are exactly 10 units from the point (–8, –2)? Check ALL that apply.

Archy [21]

Answer:

The points that are exactly 10 units from the point (–8, –2) are (2, –2) and (–8, 8).

Step-by-step explanation:

The distance formula is;

d= $\sqrt{( x_{2}-x_{1} )^{2}-(y_{2} -y_{1} )^{2} }$

So for distance between: (–8, –2) and (2, –2) is:

d= $\sqrt{( 2-(-8))^{2}-(-2 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit

Similarly for distance between: (–8, –2) and (–8, 8) is,

d= $\sqrt{( -8-(-8))^{2}-(8 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit

Solve this system of linear equations.separate the x- and y-value with a comma. -6x=-4-y -7x=-22+y.

scZoUnD [109]

Answer:

(2,8)

Step-by-step explanation:

Add them together to get rid of the y.

-6x = -4 - y

-7x = -22 + y

-13x = -26

Then solve for x.

-13x/-13 = -26/-13

x = 2

Now plug in the x value into either equation and solve for y.

-7(2) = -22 + y

-14 = -22 + y

-14 + 22 = -22 + 22 + y

8 = y

So...

x = 2

y = 8

(2,8)
