Part A: Y=4-x and Y=8-x-1 is just a fancy way of showing the point of intersection, or where both slopes meet,  so to figure out x is the point where the x meets.
Part B: Just plug in number between -3-(3) for x
Part C: Solve the equation by drawing the slope of both equations and find where both lines intersect

Ilia_Sergeevich [38]

Answer:
The fox is faster, by 7 miles per hour

Step-by-step explanation:

The fox can run 21 miles in half an hour -> It can run 42 miles in an hour

And the rabbit can run 35 miles per hour, so the fox run fastest by 42-35 = 7(m/h)

What is the answer I need help
Fudgin [204]

Answer:

The area of the figure is 36.

Step-by-step explanation:

The area formula for both sections of the figure is A = bh.  In both sections, the base is 6 and the height is 3. 6 times 3 is 18, and 18 times 2 is 36.

*For more information on the formula, look up the formula for parallelograms, and also I hope you understand the side length with two tick marks is not relevant to finding the area*
