Pls help complete for y=-7x +9 how do I do this

Answers

Answer:

You put the x in the x area and solve the problem.

For example:

For 0 you would do y=-7(0) + 9

Then if you do the math you get y = 9

Therefore, your answer is 9.

-9 on both sides so the it now be, y-9=7x then you divide both sides by 7 which will be y-9/7= x.
Hope it’s the correct answer for you

A basketball court is a rectangle that is 94 feet long. The area is 4700 square feet. What is the width of a basketball court?
A. 25 feet
B. 41 feet
C. 50 feet
D. 100 feet

Answers

Answer: C: 50 feet

Step-by-step explanation: The area of the basketball is 4700 square feet. We know that one side of the court is 94 feet long. To find the area for a rectangle, the formula would be Area=base times height. The "height" of this rectangle is 94 feet long. Now we need to find the base.

If you divide 4700 by 94, you will end up with 50 feet. To check, you multiply 50 by 94 and should end up with 4700. 50 feet is your base length.

The maximum height is 36.75feet at 2.5 seconds. Using the quadratic equation, you can calculate the x coordinate of the vertex with -b/2a. In this case, the x coordinate of the vertex is the time the swipe card reaches its max height , and it is 2.5. To calculate the maximum height, substitute 2.5 into each variable of t in the original equation, and the solution is 36.75.
