Answer:

Step-by-step explanation:

We're king of shown that it's a parallelogram, so we should assume LM = KN (we can't solve it if we don't know if it's a parallelogram).

LM = KN

3x - 4 = x + 12

2x = 16

x = 8

LM = x + 12 = 8 + 12 = 20

KN = 3x - 4 = 3*8 - 4 = 24 - 4 = 20

Answer:

Step-by-step explanation:

we know KN=LM, because it looks a parallelogram

3x-4=x+12

3x-x=12+4

2x=16

x=8

LM=8+12=20

Gordy is a goalie for a neighborhood soccer team.He played in 65% of the 20 games this season.In how man ygames did he not play?

elena-s [515]

If you would like to know in how many games Gordy didn't play, you can calculate this using the following steps:

Gordy played in:
65% of 20 games = 65% * 20 = 65/100 * 20 = 13 games

He did not play in:
20 games - 13 games = 7 games

The correct result would be B. 7 games.

Mr. Doss reached into a bag and pulled out a handful of counters. He pulled out 16 negative counters and 27 positive counters. W

Maurinko [17]

Answer: 11

Step-by-step explanation:

Given: Mr. Doss pulled out 16 negative counters and 27 positive counters.

In integers we use negative sign "-" to represent the negative quantities.

So, we can represent 16 negative counters as -16.

Now, combined value of the counters = (-16) + 27

= 27-16

= 11

Hence, the combined value of the counters is 11.

I don’t understand at all

Savatey [412]

Answer and Step-by-step explanation:

The parent function, f(x) = |x|, has no transformations applied to it.

When the number is with the x, it translates the graph horizontally. <->

When the number is outside of the absolute box, it translates the graph vertically. ^ V

When the number is multiply the absolute box on the outside with the x inside, it scales the graph.

So, first lets apply the translations of horizontal and vertical shift.

The graph translated 1 units downwards.

The graph translates 2 units to the right.

g(x) = |x - 2| - 1

We subtract the 2 because that makes it go right, while if we added it would go left.

Now for the scale.

The lines have a slope of $\frac{1}{4}$ , so that is what we are multiplying.

g(x) = $\frac{1}{4}$ |x - 2| - 1

^That is your transformed function.
