5. CD has an endpoint at (2, -1) and a midpoint at (8,3). Which measure is closest to the length of CD?

Alexus [3.1K]

Answer: C

Step-by-step explanation:

the equation for X is

$\frac{2+x}{2} =\frac{8}{1}$ use proportion to solve

2 + x = 16

x = 14

(14,y)

The equation for Y is

$\frac{-1+y}{2} =\frac{3}{1}$ use proportion to solve

-1 + y = 6

y = 7

(14,7)

now use the distance formula

(14,7) (2,-1)

which gets you 14.4 or C

Can anyone help me I was self isolating when my class was taught this and I can't get in contact with my teacher

Aleonysh [2.5K]

Answer:

Step-by-step explanation:

3x +2y = 13 -----------------(i)

x + 2y = 7 ----------------(ii)

Multiply the equation (ii) by (-1) and then add.

(i) 3x + 2y = 13

(ii)*(-1) <u>-x - 2y = -7 </u> {Now, add and y will be eliminated}

2x = 6

x = 6/2

x = 3

Plug in x = 3 in equation (i)

3*3 + 2y = 13

9 + 2y = 13

2y= 13 - 9

2y = 4

y = 4/2

y = 2
