Answer:
Every point on a horizontal line has the same y-value. Use the y-value of the point to find the equation of the horizontal line.
y=4
Answer:
Note :
The perimeter is : AB + BC + CA
AB =√((XB - XA)² + (YB - YA)²) = √((16-2)²+(2-8)²) = √(12²+6²) = √(144+36)=√180
AB = √(36×5) = 6√5 units
same method for : BC ; CA ..........
Answer:
The other endpoint of the segment is 
.
Step-by-step explanation:
The midpoint of the points 
and 
is given by the following formula:
where 
= coordinates of the midpoint.
We know that the midpoint is (-15, 2) and an endpoint is (-12, 11). Substituting the information we have gives:
To find 
we need to solve this equation:
and to find 
we need to solve this equation:
The other endpoint of the segment is 
.
45+-17
This is the same as subtracting 17 from 45
45-17=28
F(4) value is 6.
I believe it would work like this:
f(x) is being turned into f(4), so 4 would equal x. Put 4 into the equation 3x-6, and you get 12-6, which gives you 6. So the value of f(4) is 6. I hope this helps!
