Step-by-step explanation:
We use he distance formula:
distance = [tex]\sqrt{(-9 + 1)^2+(3+1)^2}=\sqrt{64+16} =\sqrt{80}[/tex]
Answer:
Step-by-step explanation:
[tex]d^2=(x_2-x_1)^2+(y_2-y_1)^2\\ \\ d^2=(3- -1)^2+(-9- -1)^2\\ \\ d^2=4^2+(-8)^2\\ \\ d^2=16+64\\ \\ d^2=80\\ d=\sqrt{80}\\ \\ d=4\sqrt{5}\\ \\ d\approx 8.9[/tex]

Find g^−1(x) when g(x)=3/5x−9.
Answers
Answer:
[tex]g^-^1(x) = \frac{5}{3} x + 15[/tex]
Step-by-step explanation:
Based on the function [tex]g(x)[/tex], we have to find the function [tex]g^-^1(x)[/tex]. This is known as finding the inverse of a function.
1) To find the inverse of a function, first take the original function and switch the places of the x and y variables like so (the [tex]g(x)[/tex] is the "y" of the function):
[tex]g(x) = \frac{3}{5}x-9\\x = \frac{3}{5}y-9[/tex]
2) Now, with the new equation, isolate y. Whatever the end result is, is the inverse of the original function, and therefore [tex]g^-^1(x)[/tex]:
[tex]x = \frac{3}{5} y-9\\x + 9 = \frac{3}{5} y\\\frac{5}{3}x + 15 = y \\g^-^1(x) = \frac{5}{3} x + 15[/tex]
Thus, [tex]g^-^1(x) = \frac{5}{3} x + 15[/tex].

What is an improper fraction? An improper fraction:
Does anyone know this?
Answers
Answer:
An improper fraction is when the numerator of the fraction is larger than the denominator
For example, 13/4 is improper because 13 > 4
An improper fraction can be changed into a mixed number by dividing the numerator by the denominator
For example, 13 divided by 4 is 3 with remainder 1, or 3 1/4
Step-by-step explanation:
Answer:
An improper fraction is when the numerator is a larger number than the denominator. An improper fraction is also what the fraction is before you simplify it down to either a whole number or a mixed number.
An example of an improper fraction simplified to a whole number is 25/5. This can be simplified down to 5.
An example of an improper fraction simplified to a mixed number is 17/3. This can be simplified down to 5-2/3.
Deanna and Lisa are playing games at the arcade. Deanna started with $15, and the machine she is playing costs $0.75 per game. Lisa started with $13 and her machine costs $0.50 per game. After how many games will the girls have the same amount of money remaining?
Answers
Answer: After they've played 8 games, they will have the same amount of money remaining.
Step-by-step explanation:
Represent the number of games by the variable x and the remaining amount of money by the variable y.
Deanna's situation can be represented by the equation y = 15 - 0.75x
Lisa's situation can be represented by the equation y = 13 - 0.50x
Now to find out how many games they will have the same amount of money remaining, you have to use substitution and solve for x.
15 - 0.75x = 13 - 0.50x
-13 -13
2 - 0.75x = - 0.50x
+0.75x +0.75x
2 = 0.25x
x = 8

Answer:
y = 120
Step-by-step explanation:
y = 4x (corresponding angles)
y + 2x = 180
substitute the value of y into the second equation
4x + 2x = 180
6x = 180
x = 30
now that we have the value of x, plug it into either equation and solve for y
y = 4 (30)
y = 120

Niles scored 70, 74, 72, 71, 73, and 96 on his 6 Geography test. Calculate the mean and median.
Answers
Answer:
Mean=76
Median=72.5
Step-by-step explanation:
Mean= 70+71+72+73+74+96
456/6=76
Median = 70,71,72,73,74,96
72+73=145/2=72.5
Mean= 76
Median= 72.5
The first step is to rearrange the numbers
70, 71, 72, 73, 74, 96
1. mean= sum of terms/number of terms
= 70+71+72+73+74+96/6
= 456/6
= 76
2. Median can be described as the middle number, the median can be calculated as follows
= 72+73/2
= 145/2
= 72.5
Hence the mean is 76 and the median is 72.5
