11% or 3/9 should be right. Hope it helps :)
First of all you know it wiill be a positive slope as both the rise and the run are negative. a negative divided by a negative equals a positive. so you can plot the points (2,3) and (-2,-3) as they will be points on this line. next you take a straight line and place it so that both points are intercepted. then extend the line outwards.
The formula d = rt describes distance traveled in time and rate of speed. However, we only have the distance and time to place in. This means d = rt would become d / t = r. Once filled in, the problem is now 76 / 1.5 which equals 50.6 (repeating bar over the 6). However, this is the AVERAGE speed of the truck (meaning we are rounding. 50.6 rounded to the nearest speed would be 51 miles per hour.
Right of the bat, I know the measure of angle C equals 73° because of the Isosceles Base Angle Theorem. Then, due to the Triangle Sum Theorem, I know that all of the measures in the triangle must add to 180°. To find this, just subtract 73 and 73 from 180. Finally, because angle B equals (6x + 4) and 34°, just set them equal to each other to find the value of x.
180 - 73 - 73 = measure of angle B
34° = measure of angle B
6x + 4 = 34
- 4 - 4
6x = 30
6x / 6 = 30 / 6
x = 5
Hope this helps!
