Answer: a. they are alternate exterior angles.
b. Since they are the same measure, 14x + 2 = 9 + 13x. Let us solve.
14x + 2 = 9 + 13x
14x + 2 = 13x + 9
14x = 13x + 9 - 2
14x = 13x + 7
14x = 7 + 13x
14x - 13x = 7
x = 7
To check let us substitute. 14 * 7 + 2 = 9 + 13 * 7
100 = 100
So, we are correct.

Answer:
Slope = -2
Step-by-step explanation:
Since, slope = 
Rise = -(y-intercept)
Run = (x-intercept)
From the graph attached,
y - intercept = -(4) = -4
x - intercept = 2
Therefore, slope the line given in the graph attached will be,
Slope = 
= -2
Slope = -2
The speed of the jet is 1302 miles per hour.
<h3><u>Speed determination</u></h3>
Since a private jet can fly 1134.6 miles against a 27-mph headwind in the same amount of time it can fly 1469.4 miles with a 27-mph tailwind, to find the speed of the jet you must perform the following calculation:
- (1469.4 - 1134.6) / 2 = X
- 334.8 / 2 = X
- 167.4 = X
- 1469.4 - 167.4 = X
- 1302 = X
Therefore, the speed of the jet is 1302 miles per hour.

Answer:
14
Step-by-step explanation:
3b/7 - 1 = 5
move the 1 over by adding
3b/7 = 6
multiply each side by 7 to get rid of the denominator
3b = 42
divide by 3
b = 14
To find a perimeter add all the sides of the shape. so 12+9+15 is 36. the perimeter of the triangle is 36
