Lol, you said 20 points but that’s only 12 but sorry I’m also failing in math☹️☹️☹️ so i don’t really know the answer
Answer:
x=39, y=180
Step-by-step explanation:
f(x)=0.4x²-31.2x+788.4
For x=39 the graph reaches its lowest point.
The minimum value of y is:
x=39→y=f(39)=0.4(39)²-31.2(39)+788.4
y=f(39)=0.4(1,521)-1,216.8+788.4
y=f(39)=608.4-1,216.8+788.4
y=f(39)=180
Answer:
You can find the midpoint of a line segment given 2 endpoints, (x1, y1) and (x2, y2). Add each x-coordinate and divide by 2 to find x of the midpoint. Add each y-coordinate and divide by 2 to find y of the midpoint. It's important to note that a midpoint is the middle point on a line segment.
In order to see the midpoint formula in use, let's look at an example.
Question:
Determine the midpoint of the line segment with the given endpoints.
A(3, 7), B(9, 1)A(3,7),B(9,1)
Solution:
We can use the formula for midpoint to determine the midpoint: M= (x1 + x2/2 , y1+y2/2)
First, plug the x and y value into the formula:
M=(3+9/2 , 7+1/2)
,
Then, we can calculate the midpoint:
(6, 4)
