Answer:
y = -2x - 5
Step-by-step explanation:
y = is a standard for any equation, as is the use of x as a variable, unless something else is specified.
-2x is the way to denote a slope of -2, and -5 gives you the y-intercept of 5. One point on this line would be (0, -5).

Which rational number has the least value?
A rational number a/b is said to be in the lowest form or simplest form if a and b have no common factor other than 1. In other words, a rational number ab is said to be in the simplest form, if the HCF of a and b is 1, i.e., a and b are relatively prime.
The truth value of the statement ""1+ 1 = 2 if and only if 2 + 3 = 4"" is *
Answer:
False
Step-by-step explanation:
1+1=2 is clearly true.
2+3=4 is clearly false.
x if and only if y has a value of true if x and y are both true or both false. It is false otherwise.
So, true if and only if false has a value of false, so the answer is [tex]\boxed{false}[/tex]

What is the probability that the average of 35 numbers will be less than 7.9?
Answer:
22.5
Step-by-step explanation:
The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.
(a) Distribution of X is uniform distribution X to U(4,11).
(b) Sample size (n) = 35, distribution of mean would be moderate with value = (4+11)/2 = 7.5
Standard deviation = √ [(11-4)^2/(12*35] = 0.3415
Now
x to N (7.5, 0.3415)
(c) We have to find probability that the average of 35 numbers will be less than 7.9.
P(x < 7.9) = P(x < 7.9; 7.5; 0.3415)
Z = (7.9 -7.5)/0.3415
Z = 1.1713
P(x< 7.9)= P(Z < 1.1713)= 0.87932.
Thus, The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.

What is the midpoint of a line with endpoints (6,5) and (14,7), (Your answer
should be an ordered pair)
Answer:
Midpoint = (10,6)
Step-by-step explanation:
Using Coordinates: X(6,5) and Y(14,7)
Using the midpoint formula: M = (X1 +Y1)/2, (X2 + Y2)/2
Midpoint of XY = (6 + 14) / 2, (5 + 7) / 2
Midpoint of XY = (20) / 2, (12) / 2
Therefore the midpoint of XY is (10,6)

6. A linear function f(x) contains the coordinates (-9, 4) and (6,4). Joy says f(x) is a horizontal
line, and Lu says f(x) is a vertical line. Which student correctly described the function?
Explain.
Answer: Horizontal Line
Step-by-step explanation:
Joy is correct. This is a horizontal line. It has the same y coordinates so it will be a horizontal line.
Joy is saying correct by saying it is a horizontal line.
What is coordinates?Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane.
Given:
coordinates (-9, 4) and (6,4)
If we plot these point on the graph it will have the y- coordinates same for both coordinates.
Also, if the graph have same y- coordinates then the line joining these points are horizontal in nature.
Hence, Joy is saying correct by saying it is a horizontal line.

What is clock?A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year.
Victoria logged in to work at 8:15 am
8:15 am →9:15 am →10:15 am→11:15 am→12:15 pm→1:15 pm→2:15 pm→3:15 pm→4:15 pm
8:15 am →9:15 am = 1 hour

10:15 am→11:15 am = 1 hour
11:15 am→12:15 pm = 1 hour
12:15 pm→1:15 pm = 1 hour
1:15 pm→2:15 pm = 1 hour
