What are the points in graph?
The objects correspond to mathematical abstractions called vertices (also called nodes or points) and each of the related pairs of vertices is called an edge (also called link or line).
Here given points are [tex](4,-6)[/tex].
So when we rotate it in [tex]90[/tex] degree so the points would be [tex](-6,4)[/tex].

One model for the number of students enrolled in U.S. Public high schools as a function of time since 1986 is N = -0.033t2 +0.46t + 13.37. Here N is the enrollment in millions of students, t is the time in years since 1986, and the model is relevant since 2000. Explain
Answer:
The number of students in a year 2010 is 14.67 millions .
Step-by-step explanation:
Here , the given model is [tex]N = -0.033t^2 +0.46t + 13.37[/tex]
The model is relevant since 2000.
N(10) represents the number of students enrolled in millions.
10 represent the number of years after 2000
Thus , 10 years after 2000 will be 2010 ,
Now put t =10 in the given model ,
[tex]N(10) = -0.033(10)^2 + 0.46(10) + 13.37[/tex]
[tex]N(10)= -0.033(100) + 0.46(10) +13.37[/tex]
[tex]N(10)= -3.3 +4.6+13.37[/tex]
[tex]N(10)= 14.67[/tex]
Hence, the number of students in a year 2010 is 14.67 millions. The correct option is A.

A game show contestant earns y dollars for completing a puzzle in x minutes. This situation is represented by the equation
y = -250x + 5000. How long did a contestant who earned $500 take to complete the puzzle?
Justify your answer
Answer:
it took them 18 minutes to earn $500
Step-by-step explanation:
Step 1: Flip the equation.
−250x+5000=500
Step 2: Subtract 5000 from both sides.
−250x+5000−5000=500−5000
−250x=−4500
Step 3: Divide both sides by -250.

For 6z=126, Chris wrote that z=756. Explain what Mike’s mistake was. Then tell the correct answer.
Step-by-step explanation:
6z=126
z = 126 ÷ 6 = 21
Chris's
z = 756
6z= 126
z = 126 × 6 = 756
correct answer = 21
the number 6 is being multiplied with z.So if the number 6 is going to the right side it will divide the number on the right side.
but for chris he multiplied the number on the right side with 6.So that is the mistake.

Find the value of k so that the line through the given points has the given slope.
(2,-3) and (k,7) m= -1
Answer:
[tex]k=-8[/tex]
Step-by-step explanation:
We have the two points: (2, -3) and (k, 7).
And we want to find the value of k such that the slope between these two points is -1.
So, we can use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (2, -3) be (x₁, y₁) and let (k, 7) be (x₂, y₂). Let's also substitute the slope m for -1. This gives us:
[tex]-1=\frac{7-(-3)}{k-2}[/tex]
So, let's solve for k. Add in the numerator:
[tex]-1=\frac{10}{k-2}[/tex]
Notice that we can rewrite the left side as:
[tex]\frac{-1}{1}=\frac{10}{k-2}[/tex]
Now, we can cross-multiply:
[tex]-(k-2)=10[/tex]
Divide both sides by -1. This removes the negative on the left:
[tex]k-2=-10[/tex]
Finally, add 2 to both sides. So, the value of k is:
[tex]k=-8[/tex]
And we're done!
