A line AB joins the points A (3,4) and B (5,8). Write down the coordinates of the midpoint of the line AB
matrenka [14]

Given:

A line AB joins the points A (3,4) and B (5,8).

To find:

The midpoint of the line AB.

Solution:

Midpoint formula:

Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

A line AB joins the points A (3,4) and B (5,8). So, the midpoint of line AB is

Midpoint=\left(\dfrac{3+5}{2},\dfrac{4+8}{2}\right)

Midpoint=\left(\dfrac{8}{2},\dfrac{12}{2}\right)

Midpoint=\left(4,6\right)

Therefore, the midpoint of the line AB is (4,6).

Given the functions f (x) = x^2 + 4 and g (x) = 3x+ 8 what is a solution for the equation ? x^2 + 4 = 3x + 8 A. 0 B. 1 C. 2 D. 4
k0ka [10]

Answer:

D

Step-by-step explanation:

Let's solve your equation step-by-step.

x2+4=3x+8

Step 1: Subtract 3x+8 from both sides.

x2+4−(3x+8)=3x+8−(3x+8)

x2−3x−4=0

Step 2: Factor left side of equation.

(x+1)(x−4)=0

Step 3: Set factors equal to 0.

x+1=0 or x−4=0

x=−1 or x=4

Answer:

x=−1 or x=4
