As the triangle is equilateral, the height is also the median.
As the median cut the side in two equal halve, and one of this half is 9, then the side is 18.
As the triangle is equilateral, every side is the same measure, so x = 18
It would take them a half and hour
Answer:
x = 8.5
Step-by-step explanation:
You have all three angles already, so it's easy: 90°, (4x - 8)°, (6x + 13)°
The sum of all angles is 180°
90 + (4x - 8) + (6x + 13) = 180
10x + 95 = 180
- 95 -95
10x = 85
x = 8.5
First find the slope between the 2 points
0--2/4--4
=2/8
=1/4
Then y=1/4 x+b
Now substitute one pair of x and y into the equation
0=1/4*4+b
b=-1
So y=1/4x-1
Done!
Step-by-step explanation:
Range is all possible y values a function can have. Look at the y axis. So let find the max/ min y value the function can have. The max y value is 1, and the minimum y value is -4. All the x Intervals fall between -4, and 1. Since we have solid dot we include the -4 and 1.
So the notation for this is
or
[-4,1]
