1.2x-4y=28 solve for y

Answers

Answer 1

Answer: 2x -4y= 28
⇒ -4y= 28 -2x
⇒ y= (28 -2x)/ (-4)
⇒ y= 28/(-4) -(2x)/ (-4)
⇒ y= -7 + 1/2x

The final answer is y= -7 + 1/2x~

Answer 2

Answer:

Final answer:

To solve for y in the equation 1.2x - 4y = 28, subtract 1.2x from both sides, divide both sides by -4, and simplify to get the solution y = -7 + 0.3x.

Explanation:

To solve the equation 1.2x - 4y = 28 for y, we need to isolate the y variable on one side of the equation.

Step 1: Subtract 1.2x from both sides.

Step 2: Divide both sides by -4.

Step 3: Simplify.

Step 4: The solution for y is -7 + 0.3x.

A coach wants to know if soccer players who warm up before a game will score more points than those who don't warm up. He will break the team up into two groups and make sure each player gets equal time on the field. He will then count how many points each player makes during the game. What statistic should he study?The standard deviation of the number of points earned by each player
The standard deviation of the number of points earned by each group
The mean number of points earned by each player
The mean number of points earned by each group

Answers

The correct answer is the last option.

Since the coach is studying the two different groups, the results will be more meaningful if the groups are compared to one another as opposed to the players. It would also make more sense to study the mean (or average) of the points scored, rather than the standard deviation (which is essentially a measure of how spread out a set of numbers are).

Answer:

The answer is The mean number of points earned by each group

Find the coordinates of m, the midpoint of gh, for g(8,-6) and h(-14,12)

Answers

Answer:

m = (- 3, 3 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint M is

M = ( $(x_(1)+x_(2) )/(2)$ , $(y_(1)+y_(2) )/(2)$ ) ← midpoint formula

let (x₁, y₁ ) = g (8, - 6 ) and (x₂, y₂ ) = h (- 14, 12 ) , them midpoint m is

m = ( $(8-14)/(2)$ , $(-6+12)/(2)$ ) = ( $(-6)/(2)$ , $(6)/(2)$ ) = (- 3, 3 )
