There aren't really "units". There is x and y. X represents the independent and y is the dependent. The vertical line up on a graph is the dependent and the horizontal is the independent. Vertical is y and horizontal is x. Hope this helps and mark as brainliest!
Line r represents the equation y= 3x-2.
Even though the y-intercept is not visible, the slope is 3. So that means the orange line is the equation
Answer:
Step-by-step explanation:
9-5 = 4
7 - (-10) = 3
9 - 4 = 5
The longest possible altitude of the third altitude (if it is a positive integer) is 83.
According to statement
Let h is the length of third altitude
Let a, b, and c be the sides corresponding to the altitudes of length 12, 14, and h.
From Area of triangle
A = 1/2*B*H
Substitute the values in it
A = 1/2*a*12
a = 2A / 12 -(1)
Then
A = 1/2*b*14
b = 2A / 14 -(2)
Then
A = 1/2*c*h
c = 2A / h -(3)
Now, we will use the triangle inequalities:
2A/12 < 2A/14 + 2A/h
Solve it and get
h<84
2A/14 < 2A/12 + 2A/h
Solve it and get
h > -84
2A/h < 2A/12 + 2A/14
Solve it and get
h > 6.46
From all the three inequalities we get:
6.46<h<84
So, the longest possible altitude of the third altitude (if it is a positive integer) is 83.
