Answer:
The average speed on level road is 65 mph
Step-by-step explanation:
Let the speed on the winding road be x mph
So the speed on the straight road will be x +20 mph
Mathematically, distance = speed * time
Distance on level road will be;
(x + 20)2
Distance on winding road will be;
x* 4 = 4x
Thus, we have;
2(x + 20) + 4x = 310
2x + 40 + 4x = 310
6x + 40 = 310
6x = 310 - 40
6x = 270
x = 270/6
x = 45 mph
The average speed on the level road is x + 20
That will be 45 + 20 = 65 mph
Answer:
y = 2x + 1
Step-by-step explanation:
The intercept is the point where the line touches the y axis. The slope is determined by calculating the rise divided by run.

Answer:

Step-by-step explanation:
By definition, a Translation is a trasformation in which a figure is moved a fixed distance in a fixed direction. In this type of transformation the size and the shape of the figure does not change.
Composition of transformations happens when two or more transformation are combined. Each transformation is applied on the image of the previous transformation.
In this case we have this Composition of translations:
→
followed by
→ 
You can notice that 5 units are subtracted from the x-coordinate in the first transformation and then 3 units are added. So, the sum is:

Observe that, in the first transformation, 7 units are added to the y-coordinate and then 0 units are added. The sum is:

Then, the single Translation that has the same effect as the given Composition of translation is:
→
