The points (5,-2) and (7,r) lie on a line with slope 4. Find the missing coordinate r.
Answer:
A slope of four means that it moves up four and over 1. Since 7-5 is 2, you must half the 1. (7, 2.5)

Suppose y varies directly with x. If y = 6 when x = 18, find the value of y when
x= 8.
Answer:
y = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition
y = 6 when x = 18 , then
6 = 18k ( divide both sides by 18 )
k = [tex]\frac{6}{18}[/tex] = [tex]\frac{1}{3}[/tex]
y = [tex]\frac{1}{3}[/tex] x ← equation of variation
When x = 8, then
y = [tex]\frac{1}{3}[/tex] × 8 = [tex]\frac{8}{3}[/tex]

What is the equation of the least-squares regression line for the data set?
A) y=−1.988x+43.293
B)y=−0.879x+43.293
C)y=1.988x−43.293
D)y=−0.879x−43.293
Answer:
The answer is option A y = −1.988x + 43.293
Step-by-step explanation:
I just took the test
The equation of the least squares regression line for the data set will be;
y = -1.988x + 43.293
Option A is true.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The table of data set is shown in figure.
Now, Let hours represent by x.
And, Tickets sold represent by y.
So, By the equation;
y = -1.988x + 43.293
Substitute x = 11;
y = -1.988 × 11 + 43.293
y = - 21.868 + 43.293
y = 21.62
y = 22
And, For x = 9;
y = -1.988 × 9 + 43.293
y = -17.892 + 43.293
y = 25.4
y = 24
Thus, Equation y = -1.988x + 43.293 shows the least-squares regression line for the data set.
So, The equation of the least squares regression line for the data set will be;
y = -1.988x + 43.293

Write an equation in slope-intercept form of the line shown. y 4 (0, 3) (4, 2) 2 2 4 x
Answer:
The slope intercept form of (0,3) and (4,2) is y= -1/4x+3
Step-by-step explanation:
The distance from our y values from 3 to 2 is -1.
The distance from our x values is 4.
We can put these values as our slope and we know that the Y values are always rise and the x values are always run
Therefore we get y= -1/4x+3 (side note: The 3 is our y intercept, this means that the x value of the three is always 0. For example, in (0,6) the y intercept would be 6.
Hope this helps! :)

solve for a. 1/3(21-3a)=6-a
Answer:
no solution
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )
21 - 3a = 18 - 3a ( subtract 21 from both sides )
- 3a = - 3 - 3a ( add 3a to both sides )
0 = - 3 ← not possible
This indicates the equation has no solution
Eduardo has to make a 10 minute video of his test corrections for his Algebra 2 teacher in order to be eligible to retest. His teacher said he must stay within three minutes of the 10 minute requirement. Write an absolute value inequality that represents video lengths that meet the requirement. No spaces. On your keyboard,
Answer:
7 ≤ v ≤ 13
Step-by-step explanation:
Length of video required must be within 10 minutes
Submitted length of video must be with 3 minutes of the 10 minutes video
To create an absolute value inequality :
Let v = the range of value for which the required video will be :
|v - 10| = ±3
Lower boundary :
|v - 10| = - 3
v = - 3 + 10
v = 7
Upper boundary :
|v - 10| = 3
v = 3 + 10
v = 13
Hence,
7 ≤ v ≤ 13

Identify the reference angle Ф for each given angle, Ф.
When ∅=300°, Ф=
=====================================================
Explanation:
The given angle is ∅ = 300. This x value is between 270 and 360, so we're in quadrant IV (the southeast quadrant)
The rule to get the reference angle y for this quadrant is
Ф = 360-∅
This tells us the angle made with the positive x axis
Ф = 360-∅
Ф = 360-300
Ф = 60
A 60 degree angle forms with the positive x axis as shown in the diagram below.

A triangular garden has two rock walls meeting at a right angle. The length of one of the walls is 20 feet. Use the image to find d, the length of the other wall.
Step-by-step explanation:
Here you go, I hope this is helpfull
The length of the other side of the wall is √500 ft
Pythagoras theorem
To get the length of 'd', we will use the pythagoras theorem as shown below:
Given the following
Hypotenuse = 30ftAdjacent = 20ftAccording to the theorem;
[tex]h^2=a^2+d^2\\30^2 = 20^2 + d^2\\900 = 400 + d^2\\d^2 = 900 - 400\\d = \sqrt{500} ft[/tex]
Hence the length of the other side of the wall is √500 ft
