Answers

Answer:

m = 11/36

Step-by-step explanation:

6/7 m - 1/7 = 5/ 42

Multiply each side by 42 to clear the fractions

42(6/7 m - 1/7) = 5/ 42 *42

36m - 6 = 5

Add 6 to each side

36m -6+6 = 5+6

36m = 11

Divide each side by 36

36m/36 = 11/36

m= 11/36

At the beginning of the day the stock market goes down 50 1/2 points and stays at this level for most of the day. At the end of the day the stock market goes up 80 1/4 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the​ day?

Answers

Answer:

The change for the day is 29 3/4

Step-by-step explanation:

In this problem, we are expected to calculate the change in the price of a particular stock

Given that the days high is 80 1/4

and also that the days low is 50 1/2

we can calculate the change by subtracting the days low from the days high

i.e 80 1/4- 50 1/2= 321/4-101/2= (321-202)/4= 119/4 = 29 3/4

hence the change for the day is 29 3/4

Also we can calculate the percentage change as

%change = (high-low)/low*100

%change= 80 1/4- 50 1/2/50 1/2= 29 3/4/50 1/2 *100

%change= 119/4*2/101 *100= 119/202*100= 0.589*100= 58.9%

%change= 58.9%

Samantha has $48 to spend on used video games. Single player games cost $6 each and multi player games cost $12 each. What equation, in standard form, determines the number of single player games (x) and the number of multi player games (y) Samantha can buy?

Answers

Answer:

The equation is

6x + 12y = 48

Step-by-step explanation:

Standard form another way of writing a linear equation. It is in the form

Ax + By = C

Total amount with Samantha = $48

Single player games = $6 each

Multi player games = $12 each

Let

Number of Single player games = x

Number of Multi player games = y

The number of single player games (x) and the number of multi player games (y) Samantha can buy is

6x + 12y = 48

That is price × quantity of single player games + price × quantity of multi player games = Total amount with Samantha

2 Answers:Choice B) ReflectionChoice F) Quadrant 2

Explanation:

The rule [tex](x,y) \to (-x,y)[/tex] has us flip the sign of the x coordinate from positive to negative (or vice versa). This applies a reflection over the y axis. For example, the point (5,6) moves to (-5,6).

Currently this shape is in quadrant 1. The quadrants start in the top right corner, and you move counterclockwise going to quadrants 2,3, and 4. Quadrant 2 is to the left of quadrant 1, and this is where all of the points end up after applying a reflection over the y axis.
