What is 2x - 3 if x equals 7?

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!

Answer:

A. -13 feet

Step-by-step explanation:

absolute value has no negatives. it looks like this : |-13|

so once you take all the negatives away, you can easily spot the least one.

the reason why there is absolute value is for things like distance. You can't have negative distance because you just can't say "hey I walked -3 miles yesterday". Therefore, this question is also asking for which fish is closest to the water's surface.

Step-by-step explanation:

The solution is : 6 feet describes the center, and 9 feet describes the spread

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.

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

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.

The slope of a line is the ratio that determines the steepness as well as the direction of the 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:

(3 - 0)/(0 + 3) = 1

(3 - 0)/(1 - 0) = 3

(1 - 0)/(3 - 0) = 1/3

(29.1 - 4.8)/(9.7 - 1..6) = 3.111

(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.
