Let s be an integer. Alonso claims that -s must always be less than 0. IIiana claims that -s is only sometimes less than 0. Whose statement is correct? Help please.

Answers

Iliana is correct since an integer means a whole number that is not a fraction, which includes negative AND positive numbers. If s=4 than -s is negative (-4) But if we plug in a negative integer, like -5, the negative signs are eliminated and it becomes positive, therefore Alonso is wrong (-s=-(-5)=5) If the question was about a natural number Alonso would have been right since natural numbers are only from 0 and above

A spinner is divided into many sections of equal size. Some sections are red, some are blue and the remaining are green. The probability of the arrow landing on a section colored red is 9/20. The probability of the arrow landing on a section colored blue is 6/20. What is the probability of the arrow landing on a green-colored section? A. 15/20
B. 11/20
C. 6/20
D. 5/20

Answers

It’s D. 9/20 + 6/20 = 15/20, which is the probability of getting green and red combined. Since you want to find the probability of landing on the green section, you subtract 15/20 from 20/20 to get 5/20

Step-by-step explanation:

Fill out the function table for this
equation: y = x + 5

Answers

Function Table Tutorial:

We start the function table at the y-intercept, which is listed as 5 in this equation. Since this is at the y-intercept, the x-value would be 0.

(0,5)

Next you use the slope to find the next x and y values. The slope is x, or 1. So whenever you move up a 1 x-value, you'll also move up 1 y-value.

(1,6)

A thing to consider is that you can just plug in any x-value you want and then you can solve the equation to get the y-value that goes with it.

Example:

y = x + 5 ---> y = 2 + 5 ---> y = 7

By doing this, you can easily get all of the functions in the table.(

The first few functions of y = x + 5:

If (8, −9) and (6, −3) are the endpoints of the diameter of a circle, what is the equation of the circle?

Answers

$(x-7)^(2) + (y+6)^(2) = 10$ is the equation of the required circle.

Step-by-step explanation:

Step 1 :

Let A = (8,-9) and B = (6,-3) be the endpoints of the diameter of the given circle.

We need to determine the circle's equation with this diameter

Step 2 :

The mid point of the diameter will be center of the required circle.

Let M = (x,y) be the mid point of the circle.

So we have x = (8+6)÷ 2 , y = ((-9) + (-3)) ÷ 2

M = ( 7, -6) is the midpoint of the diameter and the center of the circle.

Step 3 :

The radius of the circle is distance between midpoint and any one of the end point of the diameter that is distance between point A(8,-9) and M ( 7,-6)

Distance between the 2 points $(x_(1) ,y_(1)) and (x_(2) ,y_(2))$ is given by
