Answer:
well, pick any old x, like for example x = 0
find y
0 - y = 9
y = -9
so
(0 , - 9)
now pick another x, like x = 1
3 - y = 9
y = 3-9 = -6
so
( 1 , - 6 ) and on and on until bored

How do I turn (7, -1) and (21, -5) into slope intercept form
Answers
I think the easiest way to do this is through point slope form, but first you’ll need to find your slope.
To make it easier first you want to label your points x1, y1, x2, y2
7 is x1
-1 is y1
21 is x2
-5 is y2
the formula to find the slope is
y2-y1
m= ———
x2-x1
then you’re going to plug in all the numbers
it should look like this
-5 + 1
m= ———
21-7
hint: two negative makes a positive that’s how it ended up being plus 1
then do you math.
you should end up with -4/14
which simplifies to -2/7
NOW you need to find the “b” by doing point slope
formula: y-y1 = m(x - x1)
you’re only plugging things in for y1, m, and x1.
so you’re equations should look like this
y + 1 = -2/7(x - 7)
REMEMBER( two negatives make a positive.. that’s why it’s + 1 and not -1)
Distribute -2/7
y+1 = -2/7x + 2
Subtract 1 from 2
y = -2/7x + 1
Andd done.

A student ran out of time on a multiple choice exam and randomly guessed the answers for two problems. Each problem had 4 answer choices - a, b, c, d - and
only one correct answer. What is the probability that he answered both of the problems correctly?
Answers
Answer:
We can break this down:
The student has a one out of five chance of getting a correct answer, and a four out of five chance of an incorrect answer. We can express the students odds of getting one incorrect answer as 4/5. In order to get the odds of two wrong answers, we need to multiply this answer again by the odds of choosing a wrong answer. Therefore:
The odds of one wrong answer = 4/5
The odds of two wrong answers = (4/5) * (4/5) = 16/25 chance of getting both of the questions wrong.

C) a reflection across the y-axis
D) a translation 3 units down and 7 units left
Answers
The transformation below that caused AB to transform into A'B' is a reflection across the y-axis
How to translate a coordinate point to anotherGiven the following coordinates
A = (6, 2)
B = (2, 6)
A' = (-6, 2)
B' = (-2, 6)
According to the reflection rule, the reflection over y axis is given as:
[tex](x,y)\rightarrow (-x,y)[/tex]
Note that the x-coordinate was negated as seen from the translation A to A' and B to '.
Hence the transformation below that caused AB to transform into A'B' is a reflection across the y-axis

Suppose Abby tracks her travel time to work for 60 days and determines that her mean travel time, in minutes, is 35.6. Assume the travel times are normally distributed with a standard deviation of 10.3 min. Determine the travel time
such that 26.11% of the 60 days have a travel time that is at least
.
You may find this standard normal distribution table or this list of software manuals useful. Give your answer rounded to two decimal places.
Answers
Using the normal distribution, it is found that the the travel time such that 26.11% of the 60 days have a travel time that is at least is of 42.19 minutes.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of [tex]\mu = 35.6[/tex].The standard deviation is of [tex]\sigma = 10.3[/tex].The travel time such that 26.11% of the 60 days have a travel time that is at least X when Z has a p-value of 1 - 0.2611 = 0.7389, hence X when Z = 0.64, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.64 = \frac{X - 35.6}{10.3}[/tex]
[tex]X - 35.6 = 0.64(10.3)[/tex]
[tex]X = 42.19[/tex]
The travel time such that 26.11% of the 60 days have a travel time that is at least is of 42.19 minutes.

Use intercepts to graph the linear equation -12x+3y=24
Answers
Answer:
Step-by-step explanation:
-12x + 3(0) = 24
-12x + 0 = 24
-12x = 24
-12x/-12 = 24/-12
x = -2
The x intercept would be (-2,0)
Y intercept is when x = 0, so let’s do that next.
-12(0) + 3y = 24
0 + 3y = 24
3y = 24
3y/3 = 24/3
y = 8
The y intercept would be (0,8)

This is Linear Equation. The Sum of three numbers is 27. The second number is three times the first, while the third is twice the first, Find the average.
Answers
Answer:
average = 9
(the third number is the average)
Step-by-step explanation:
If the sum of three numbers is 27, then the average (mean) is the total (27) divided by the number of values (3):
⇒ 27 ÷ 3 = 9
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
However, if you want to find the actual numbers:
Let x = first number
Let y = second number
Let z = third number
Given:
The sum of three numbers is 27 ⇒ x + y + z = 27The second number is three times the first ⇒ y = 3xThe third number is twice the first ⇒ z = 2xSubstitute y = 3x and z = 2x into x + y + z = 27 and solve for x:
⇒ x + 3x + 2x = 27
⇒ 6x = 27
⇒ x = 4.5
y = 3x
⇒ y = 3 x 4.5
⇒ y =13.5
z = 2x
⇒ z = 2 x 4.5
⇒ z = 9
Therefore, x = 4.5 y = 13.5 and z = 9
which means z (the third number) is same value as the average

PEMDAS stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
In this problem we do not have parenthesis or exponents, so we can go ahead and skip to multiplication. So:
8 x 18 ÷ 4 + 15
144 ÷ 4 + 15
Now we can go to doing division.
144 ÷ 4 + 15
36 + 15
Now we can do addition.
36 + 15
So, the answer is 51.
