Answers are:
A. 5,6,8
B 3,5,6
D 5,5,9
Answer:
x = 7
Step-by-step explanation:
Notice that in the triangle, the angle is either known or in terms of x. This means we can make an equation: 82 + (9x - 6) + (6x - 1) = 180. Now, add up tthe terms to get 15x + 75 = 180, or 15x = 105 or x = 7.
Answer:
A. 
Step-by-step explanation:
Let 
be the equation of the perpendicular line.
Two perpendicular lines have slopes with product equal to -1. The slope of the given line is 
Hence,
is the slope of needed line.
This line passes through the point (-4,2), so its coordinates satisfy the equation:
Therefore, the equation of the line is
Both of these are linear functions:
Distance A is d=2.5h and is proportional to time because the distance is just 2.5 times however many hours you have traveled.
Distance B is d= 2(h-1) + 4. This is not proportional to time but it is a linear function.
Answer:
Step-by-step explanation:
250 divided by 20= 12.5
So 12.5 miles per gallon.
