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%.
Hope this helps! Have a great Tuesday!
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.

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.

Ellen bought new fish for her home aquarium. She bought 4 Turquoise Guppies and 3 Sunburst Tetra GLO Fish and spent a total of $41.73. Danielle bought 3 Turquoise Guppies and 5 Sunburst Tetra GLO Fish for a total of $56.02. How much was one Turquoise Guppy.
Answer: Ellen: 4t + 3s = 41.73
Danielle: 3t + 5s = 56.02
t = $3.69 each
Step-by-step explanation:
with 4t + 3s = 41.73 and 3t + 5s = 56.02
you need yo eliminate s to get t so multiply 3t + 5s = 56.02 by -3/5 to get
-9/5t - 3s = -33.612 then add 4t + 3t = 41.73 to get
11/5t = 8.118 then divide 8.118 by 11/5 to get
t = 3.69

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
