To become a member at an art museum costs $60. If
you are a member art lessons will cost $2 for each
class. If you are not a member lessons will cost $6
each. Which system of equations would be used to
solve for how many lessons it would take member and
nonmemeber to cost the same.
Answer:
10
Step-by-step explanation:
If your not a member it would cost 6 member lessons because 60 by 6=10
6=1 lesson
12=2 lessons
18=3 lessons
24= 4 lessons
30=5 lessons
36=6 lessons
42=7 lessons
48=8 lessons
54=9 lessons
60=10 lessons
If your are ready and member the 30 because 2$ if for 1 lesson so 30 lessons x 2$ each is 30.
Hope it helps have a great day

Answer:
-1/10
Step-by-step explanation:
welp it is going down to the right so you know it is a negative slope only leaving the last 2
100 is your y and 1000 is your x
100/1000
and make it negative
-1/10
Answer:
1/10
Step-by-step explanation:
For this problem, since we are finding slope, we can use rise/run.
the "rise", or height, of the mountain is 100 meters
the "run", or length, of the mountain is 1000 meters
rise/run
100/1000
simplify:

Answer:
-32
Step-by-step explanation:
First you have to solve the numbers in the parenthesis which would be (8-4)= 4 then there is a 2 that you have to multiply which would be 4x2=8, then you have to solve the other parenthesis (4-8)=-4 so then you end up with 8x-4 which equals -32
Answer:
-8
Step-by-step explanation:
write the equation of a line that passes through the points (5,-9) and (-3,6)
Answer:
Step-by-step explanation:
We need to find the slope first, and we'll use the formula rise/run.
6 - -9/ -3 - 5 = 15/-8.
Our slope is -15/8.
Now, we need to find the y-intercept, which is b.
y = mx+b.
m is the slope, so y=-15/8x+b
Now, let's replace x with 5 from that point and replace y with -9 from that same point.
-9 = -(15/8)(5) + b
-72/8 = -75/8 + 3/8
So, the equation is y= -15/8x + 3/8
Use a linear equation to solve the word problem.
Two truck rental companies have different rates. V-Haul has a base charge of $75.00 , plus $0.50 per mile. W-Haul has a base charge of $69.10, plus $0.55 per mile. For how many miles would these two companies charge the same amount?
If a driver drives miles___________, those two companies would charge the same amount of money.
The equations are

Which expressions are equivalent to 2 ln a 2 ln b - ln a? Check all that apply. Ln ab2 - ln a ln a 2 ln b ln a2 ln b2 - ln a 2 ln ab ln ab2.
Equivalent expressions are expressions with same simplified form. Equivalent expressions for the given expression are;
Expression 2: [tex]\ln(a) + 2\ln(b) = \ln(a) + \ln(b^2) = \ln(ab^2)[/tex]Expression 3: [tex]\ln(a^2) + \ln(b^2) - \ln(a) = \ln(a^2b^2/a) = \ln(ab^2)[/tex]Expression 5: [tex]\ln(ab^2)[/tex]What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
What is logarithm and some of its useful properties?When you raise a number with an exponent, there comes a result.
Lets say you get
[tex]a^b = c[/tex]
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = log_a(c)[/tex]
Some properties of logarithm are:
[tex]log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})\\\\log_a(b^c) = c \times log_a(b)\\\\log_b(b) = 1\\\\ log_a(b) + log_b(c) = log_a(c)[/tex]
Log with base e = 2.71828.... is written as [tex]\ln(x)[/tex] simply.
The expression given is [tex]2\ln(a) + 2\ln(b) - \ln(a)[/tex]
We get its simplified form as
[tex]2\ln(a) + 2\ln(b) - \ln(a) = \ln(a) + \ln(b^2) = \ln(ab^2)[/tex]
Simplifying given expressions:
Expression 1: [tex]\ln(ab^2) - \ln(a) = \ln(ab^2/a) = \ln(b^2)[/tex]This isn't same as simplified form of original
. Thus , this expression is not equivalent to the given expression.
Expression 2: [tex]\ln(a) + 2\ln(b) = \ln(a) + \ln(b^2) = \ln(ab^2)[/tex]This is same as simplified form of original expression. Thus , this expression is equivalent to the given expression.
Expression 3: [tex]\ln(a^2) + \ln(b^2) - \ln(a) = \ln(a^2b^2/a) = \ln(ab^2)[/tex]This is same as simplified form of original expression. Thus , this expression is equivalent to the given expression.
Expression 4: [tex]2\ln(ab) = \ln((ab)^2) = \ln(a^2b^2)[/tex]This isn't same as simplified form of original expression. Thus , this expression is not equivalent to the given expression.
Expression 5: [tex]\ln(ab^2)[/tex]This is same as simplified form of original expression. Thus , this expression is equivalent to the given expression.
Thus, equivalent expressions for the given expression are;
Expression 2: [tex]\ln(a) + 2\ln(b) = \ln(a) + \ln(b^2) = \ln(ab^2)[/tex]Expression 3: [tex]\ln(a^2) + \ln(b^2) - \ln(a) = \ln(a^2b^2/a) = \ln(ab^2)[/tex]Expression 5: [tex]\ln(ab^2)[/tex]Learn more about equivalent expressions here:

In the figure, ∠4 is an exterior angle to triangle ∠A∠U∠L .
(a) What is the angle measurement of Angle 3? Explain the angle relationship you used.
(b) What is the angle measurement of Angle 4? Explain the angle relationship you used.
(c) What is the angle relationship between angles 1, 2, & 3? What do you notice that is similar and different between the angle relationship between angles 1, 2, & 3 and that between 3 & 4?
(d) The combination of which two angles in the triangle equal angle 4? Use your work from Part C to figure out why this is the case, and explain your conclusion.
ANSWER ALL 4 PARTS FULLY AND EXPLANITORY!
Hmmm...
(a)The angle measurement is
180-25-52=
180-77=
103 degreesWe calculated it this way because angle 3 was inside of a triangle, and we know that all the interior angles of a triangle would add up to 180. Two angles are already given as well, so we just need to subtract them to find out the angle of Angle 3
(b)Angle 4 is just
180 minus Angle 3
which is
180-103=
77I used supplementary angles
(meaning two angles add up to 180)
(c)The angle relationship between Angles 1,2,and2 is supplementary angles because they all add up to 180 degrees. The angle relationship for Angles 3 and 4 are the same because they also add up to 180. I noticed that they are both supplementary, but one set of angles(3 and 4, specifically) only require two angles to become supplementary while the other set needs three(it's a triangle).
(d)The combination of Angle 1 and 2 equals angle four. From question one, we derived that Angle 1 plus Angle 2 equals 77. From question two, we found out angle two equals 77. From part c, We procured that
Angle 1 + Angle 2 + Angle 3 = Angle 3 + Angle 4
Subtracting Angle 3 on both sides, we end up with:
Angle 1 + Angle 2=Angle 4-Hunter

What is the equation of the line that passes through the points (6,6) and (9,8)?
Answer:
[tex]y=\frac{2}{3}x+2[/tex]
Step-by-step explanation:
The equation for a line is:
y=mx+b
m=slope
b=y-intercept
x,y=(x,y) coordinate pair
Start by finding the slope. The equation for slope is...
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the given coordinates into the equation
[tex]Slope=\frac{8-6}{9-6}=\frac{2}{3}[/tex]
Now, we can use the slope and an x,y coordinate pair to find the y-intercept...
y=mx+b
6=2/3(6)+b
6=12/3+b
6=4+b
Subtract 4 from both sides
b=2
Therefore the equation is...
[tex]y=\frac{2}{3}x+2[/tex]

Answer:
42 miles
Step-by-step explanation:
32% is the same thing as 0.35
Think of the word "of" as multiplication.
Therefore, 0.35 of 120 miles is 0.35×120
This equals 42 miles.

B. f(x) = 15/2x - 20
C. f(x) = 10x − 4

Answer:
B. f(x) = 15/2x - 20
Step-by-step explanation:
Hi there!
All of the given functions are organized in slope-intercept form:
[tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept. The y-intercept is also the value of y where the line crosses the y-axis.
Notice how in the graph, the line crosses the y-axis at y = -20. This means that the y-intercept (b) is -20.
[tex]y=mx-20[/tex]
We know now that the answer is either B or D.
In the graph, the line crosses the point (4,10). Let's find f(4) of both the functions given in B and D and see which answer is equal to 10.
Function B:
[tex]f(x) = \displaystyle\frac{15}{2}x - 20\\\\f(4) = \displaystyle\frac{15}{2}(4) - 20\\\\f(4) = 30 - 20\\\\f(4) = 10[/tex]
Therefore, because f(4) is equal to 10 for function B, B is therefore the correct answer.
I hope this helps!
