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

frutty [35]

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

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

If y=-16 when x=4 find x when y=48

MatroZZZ [7]

Answer:

x= -12

Step-by-step explanation:

Assuming this is a direct variation

y = kx

When y = -16 x =4 we can find k

-16 = k*4

Divide each side by 4

-16/4 = 4k/4

-4 =k

y = -4k

Y = 48

48 = -4x

Divide each side by -4

48/-4 = -4x/-4

-12 =x
