Answer:

(x - 2)^2 + (y + 4)^2 = 29

Step-by-step explanation:

(x – h)^2 + (y – k)^2 = r^2

The radius is gotten from the pythagorean theorem and using the points (2,-4) and (4,1) I hope this is correct

Write an equation in slope-intercept form that goes through the point (5, -3) and is parallel to y = 3x - 1.

Nesterboy [21]

Answer:

$y = 3x -18$

Step-by-step explanation:

For this case we have this point given (5,-3) and we want to create an slope intercept formula given by:

$y = mx +b$

And this equation needs to be parallel to y= 3x-1 so then the slope needs to be equal m =3 and then we can use the point given to find the intercept b like this:

$-3 = 3*5 +b$

$b = 3-15=-18$

And the formula for the slope would be given by:

$y = 3x -18$

In a certain Algebra 2 class of 29 students, 7 of them play basketball and 14 of them

Mariulka [41]

Answer:

Two possible answers below

Step-by-step explanation:

Probability and Sets

We are given two sets: Students that play basketball and students that play baseball.

It's given there are 29 students in certain Algebra 2 class, 10 of which don't play any of the mentioned sports.

This leaves only 29-10=19 players of either baseball, basketball, or both sports. If one student is randomly selected, then the propability that they play basketball or baseball is:

$\displaystyle P=\frac{19}{29}$

P = 0.66

Note: if we are to calculate the probability to choose one student who plays only one of the sports, then we proceed as follows:

We also know 7 students play basketball and 14 play baseball. Since 14+7 =21, the difference of 21-19=2 students corresponds to those who play both sports.

Thus, there 19-2=17 students who play only one of the sports. The probability is:

$\displaystyle P=\frac{17}{29}$

P = 0.59
