Find the coordinates of the midpoint of a segment with the endpoints (16,5) & (28,-13)

frutty [35]

$\text{The formula of the midpoint of a segment with the end points:}\\\\A(x_A;\ y_A)\ \text{and}\ B(x_B;\ y_B)\\\\M_{AB}=\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)$

$\text{We have:}\\A(16;\ 5)\to x_A=16;\ y_A=5\\B(28;\ -13)\to x_B=28;\ y_B=-13\\\\\text{substitute:}\\\\M_{AB}=\left(\dfrac{16+28}{2};\ \dfrac{5+(-13)}{2}\right)=\left(\dfrac{44}{2};\ \dfrac{-8}{2}\right)=(22;\ -4)$

Please answer correctlyyyyyyy

spin [16.1K]

Answer: Choice C

x intercept is (4,0)

y intercept is (0,2)

=======================================================

Work Shown:

To find the x intercept, we plug in y = 0 and solve for x

2x+4y = 8

2x+4(0) = 8

2x+0 = 8

2x = 8

x = 8/2

x = 4

We have x = 4 pair up with y = 0. So we have (x,y) = (4,0) as the x intercept.

This is the location where the graph crosses the x axis.

--------------

The y intercept is a similar story, but we use x = 0 to find y.

2x+4y = 8

2(0)+4y = 8

0+4y = 8

4y = 8

y = 8/4

y = 2

The value x = 0 leads to y = 2. This gets us (x,y) = (0,2) as the y intercept.

This is the location where the graph crosses the y axis.

The answer is A, since 8 and 6 go together while you're trying to find the height for x.

Step-by-step explanation:

Step 1: Define

35 + 0.8x = 43 - 7x

Step 2: Solve for x

[Addition Property of Equality] Add 7x on both sides: 35 + 7.8x = 43
[Subtraction Property of Equality] Subtract 35 on both sides: 7.8x = 8
[Division Property of Equality] Divide 7.8 on both sides: x = 1.02564
