Answer:
Use these variables to make an equation-
y is the total amount.
$50 is where you start charging(y-intercept, variable b).
x is how many visits Marsha made.
The equation can be in slope-intercept form (y=mx+b)-
$144=$2x+50
Solve for x using inverse operations.
Subtract 50 from both sides-
144-50=2x+50-50
94=2x
Divide 2 from both sides-
94/2=2/2
x=47
Moselle made 47 visits to the health club.
Step-by-step explanation:
Two accounts earn simple interest. The balance y (in dollars) of Account A after x years can be modeled by y=10x+500. Account B starts with $400 and earns 5% simple annual interest.
1)
A has a greater principal
2)
Principal of A is $500, the principal of B is $400, so A's principal is greater by $100
3)
Annual interest rate of A:
10/500 x 100
The interest rate of B is higher.
4) B's annual interest rate is 5% and A's annual interest rate is 2%, so B's is higher by 3%.

Which relationships have the same constant of proportionality between y and x as in the equation y = 1/3 x?
Answer:
C
Step-by-step explanation:
The x is 3 and the y is 1 so if you divide the x by 3 it is 1 which is the y.
The relationships which have the same constant of proportionality between y and x as in the equation y = 1/3x are C and E.
What is the slope of a line?The slope of a line is the ratio that determines the steepness as well as the direction of the line.
How to find the slope of a line?Let the two points on a line be [tex](x_{1} , y_{1} )[/tex] and [tex](x_{2} , y_{2 )[/tex]. The slope can be found as follows:
[tex]\frac{(y_{2} -y_{1} )}{(x_{2} -x_{1} )}[/tex]
The constant of proportionality in the given problem can be understood as the slope of the line. Thus the lines with their slopes as 1/3 will have the same constant of proportionality as the equation y = 1/3 x.
We can observe the graphs given and find their respective slopes. It can be done as follows:
Graph A:(3 - 0)/(0 + 3) = 1
Graph B:(3 - 0)/(1 - 0) = 3
Graph C:(1 - 0)/(3 - 0) = 1/3
Graph D:(29.1 - 4.8)/(9.7 - 1..6) = 3.111
Graph E:(0.8 - 0.5)/(2.4 - 1.5) = 1/3
Therefore, graphs C and E have relationships that have the same constant of proportionality between y and x as in the equation y = 1/3 x.

The Silvertons are looking at purchasing a new car for their family. Steve Silverton wants to purchase a 2019 Chevrolet Tahoe which will cost an initial amount of $2000 at the door and monthly payments that are 14.45% the amount of the initial down payment. Sally Silverton wants a more eco-friendly car and would rather buy a 2021 Nissan Leaf for an initial amount of $600 at the door and monthly payments that are 62.50% of the initial amount paid. In how many months would both options have the same amount paid off?

You can automatically rule out A and C because they're too big of a fraction. The common denominator between 8 and 9 is 72, and if you covert the fractions to [tex]\frac{32}{72}[/tex]([tex]\frac{4}{9}[/tex]) it's larger than [tex]\frac{9}{72}[/tex]([tex]\frac{1}{8}[/tex])

1. -3x+32= -x-12 2. 8x+16=x+9 3. 3x + 2 = 2x -55 I need all the steps to all three of those questions
Answer:
Step-by-step explanation:
1. - 3x + 32 = - x - 12
-3x + x = - 12 - 32
-2x = - 44
x = 44/2 = 22
2. 8x + 16 = x + 9
8x - x = 9 - 16
7x = - 7
x = - 7/7
= - 1
3. 3x + 2 = 2x - 55
3x - 2x = - 55 - 2
x = - 57

What is median?In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.
here, we have,
The center of a data set is mostly considered as the median or the mean
Here mean is 6 (given). And median is also 6.
As 6 is exactly at the middle of the data set. (When arranged in ascending order)
Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.
Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.
