for some real number A, the graph of the line Y=(A+1)x+8 in the standard (x,y) coordinate plane passes through (2,6). What is th
kondaur [170]

Answer:

  -1

Step-by-step explanation:

The given equation has a y-intercept of 8, so goes through the point (0, 8).

If the line also goes through the point (2, 6) it has a slope of ...

  (y2 -y1)/(x2 -x1) = (6 -8)/(2 -0) = -2/2 = -1

The slope of the line is -1.

_____

The value of A is -2.

Suppose a researcher is testing to see if a basketball player can make free throws at a rate higher than the NBA average of 75%.
stich3 [128]

Answer: A. Repeated results if the player makes 75% of his shots in the long run.

Step-by-step explanation:

The null distribution is always the opposite of the alternative distribution which in most cases represents the claim or hypothesis which is to be tested or performed. In the scenario given, the challenge is to show that a basketball player has an average higher than that of the NBA. NBA average stands at 75%. The alternative hypothesis is the claim, which is ;

H1 : μ > 75%

THE null is thus :

H0 : μ = 75% ; which means that repeated result of the player will yields an average of 75%

Solve the system by substitution
Lina20 [59]

Answer:

(-5, -30)

Step-by-step explanation:

We start with the equation:

y = 6x

y = -4x - 50

Since both of them are equal to y, we can substitute the 6x into y. So:

6x = -4x - 50

Now we can solve for x. Add 4x to both sides...

6x = -4x - 50

+4x   +4x

10x = -50

Now, divide both sides by 10.

<u>10x</u> = <u>-50</u>

10      10

x = -5

So, we now know that x is -5. Now we know this, we can substitute -5 where we see x. It works in both equations, so I will do both.

y = 6(-5)

y = -30

And...

y = -4(-5) - 50

y = 20 - 50

y = -30

As you can see, both equations show that y = -30. To check our work, let's plug in the values.

-30 = 6(-5)

-30 = -30

Also:

-30 = -4(-5) - 50

-30 = -20 - 50

-30 = -30

So, we can see that both of the equations gave us the same answer. So, our answer is x = -5 and y = -30, so the ordered pair is: (-5, -30). Hope this helps you!
