Answer:
The missing coordinate, 'r', is 3
Step-by-step explanation:
The given parameters of the two points are;
The coordinates of the given points = (4, -17) and (8, r)
The slope of the line on which the two points lie, m = 5
The formula for finding the slope of a line is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, we have;
[tex]m =5 = \dfrac{r-(-17)}{8-4} = \dfrac{r + 17}{4}[/tex]
[tex]5 = \dfrac{r + 17}{4}[/tex]
5 × 4 = r + 17
r = 20 - 17 = 3
r = 3

In this scatterplot, the horizontal axis indicates years
since 2000 and the vertical axis indicates the population
of a pack of wolves. The equation of a trend line is also
given. Use it to predict the population in 2016.
11
Answer:
Population of wolves in 2016 = 23
Step-by-step explanation:
Equation of the line of best fit has been given as,
y = 1.5x - 1
Here, y = population of a pack of wolves
x = duration (in years) since year 2000
Duration between year 2000 and 2016 = 16 years
Now we substitute the value x = 16 in the equation of line of best fit,
y = 1.5(16) - 1
y = 24 - 1
y = 23
Therefore, population of wolves in 2016 = 23

Answer:
the third one
Step-by-step explanation:
bc like there are 2 boxes of 1 and 5 boxes of 1/6 so thats already 2 and 5/6 which applies to all of them. then there is 1 box of 1 and 2 boxes of 1/3 so thats 1 and 1/3 which applies to all of them also but when you make them have the same denominator you get 2 and 5/6 + 1 and 4/6 which deletes the second one. When you add you should get the same denominator so that deletes the first one so then you simplify that and the fraction should still be equal to the unsimplified fraction so you should get 4 and 1/2 if that makes sense

Line segment XY is located at X(2, 6) and Y(4,8). If the line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4). What are the coordinates of X'?
Given:
Line segment XY is located at X(2, 6) and Y(4,8).
The line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4).
To find:
The coordinates of X'
Solution:
If a figure dilated by a scale factor k with a center of dilation (a,b), then the rule of dilation is:
[tex](x,y)\to (k(x-a)+a,k(y-b)+b)[/tex]
The line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4). So, the rule of dilation is
[tex](x,y)\to (2(x-(-3))+(-3),2(y-4)+4)[/tex]
[tex](x,y)\to (2(x+3)-3,2y+2(-4)+4)[/tex]
[tex](x,y)\to (2x+6-3,2y-8+4)[/tex]
[tex](x,y)\to (2x+3,2y-4)[/tex]
The coordinate of X are (2,6).
[tex]X(2,6)\to X'(2(2)+3,2(6)-4)[/tex]
[tex]X(2,6)\to X'(4+3,12-4)[/tex]
[tex]X(2,6)\to X'(7,8)[/tex]
Therefore, the coordinates of X' are (7,8).

(a^2- 8a- 26) / (a + 2) simplified
Answer:
a-10 - 6/a+2
Step-by-step explanation:
The simplification of the expression (a²- 8a - 26) / (a + 2) is (a - 10) - 6/(a + 2).
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
As per the given b,
(a²- 8a - 26) / (a + 2)
First quotient = a
Remainder = -10a - 26
Second quotient = -10
Remainder = -6
By quotient remainder theorem,
(a²- 8a - 26) = (a + 2)(a - 10) - 6
Thus,
[(a + 2)(a - 10) - 6]/(a + 2) = (a - 10) - 6/(a + 2)
Hence "The simplification of the expression (a²- 8a - 26) / (a + 2) is (a - 10) - 6/(a + 2)".

Find the missing angle.
Answer:
45 Degrees
Step-by-step explanation:
This would be a right angle. The other side would be 45 Degrees. Which when you add them equals 90.
Answer:
45 degrees
Step-by-step explanation:
The following figure shown is a square
All of the angles in a square are right angles meaning that they equal 90
If a diagonal line cuts through the middle then it splits the right angle into to 45 degree angles therefore your answer is 45 degrees
John consistently saves
7/12
of his monthly salary. John's salary has recently been increased by $312.
As a result of the pay raise, John's monthly savings is now $1512. How much was John's salary before
the pay raise?
Answer:
2280
Step-by-step explanation:
As in understandable steps,
1512x12 = 18144
18144 / 7
= 2592
2592 - 312
= 2280
An equation is formed of two equal expressions. John's salary before the pay raise is $2280.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the pay of John before the raise be x.
As it is stated that John's pay was increased by $312. And he saves 7/12 of his pay which is equal to $1512. Therefore, the equation that can represent the current saving John has,
[tex]\dfrac{7}{12}(x+312)=1512\\\\(x+312) = \dfrac{1512 \times 12}{7}\\\\x+312= 2592\\\\x =2592-312\\\\x = 2280[/tex]
Hence, John's salary before the pay raise is $2280.
