Step-by-step explanation:

a. parameter = (3x)+(3x)+(4x+3)+(4x+3) = 14x+6

b. area = (3x)(4x+3) = 12x²+9x

c. parameter = 14(2)+6 = 34

d. area = 12(2²)+9(2) = 66

e. parameter = (3x+1)+(3x+1)+(4x+3)+(4x+3) = 14x+8

How can you tell which function has the greatest constant of variation?

alekssr [168]

The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities.

The formula for direct variation is

y=kx (or y=kx)

where kk is the constant of variation.

Example 1:

If y varies directly as x and y=15 when x=24,

find x when y=25 .

Find the constant of variation.

k=y/x=15/24=5/8y=5/8x

To find x, substitute 25 for y.

25=5/8x

x=40

The constant of variation in an indirect variation is the constant (unchanged) product between two variable quantities.

The formula for indirect variation is

xy=k (or y=k/x )

where k is the constant of variation .

Example 2:

If it takes 4 hours at an average speed of 90 km/h to do a certain journey, how long would it take at 120 km/h?

Find the constant of variation.

k = speed · time

k=90⋅4=360

Then,

time=k/speed =360/120 =3 hours.

Click and drag to draw a ray from the yellow dot.

miv72 [106K]

Answer:

1/2(m∠JKL) = m∠JKM

Step-by-step explanation:

The angle JKL is being bisected by line KM. This means that the angle has been split into 2 equal angles. Therefore, one of these angles will be equal to 1/2 of the large angle. So, option B, 1/2(m∠JKL) = m∠JKM, is correct.

Can somebody help me with this?

Natasha_Volkova [10]

Step-by-step explanation:

Hey there!

By looking through figure, l and m are parallel lines and a transversal line passes through the lines.

Now,

7x + 12° = 12x - 28°( alternate angles are equal)

12°+28° = 12x - 7x

40° = 5x

$x = \frac{40}{5}$

Therefore, x = 8°

Now,

12x - 28° + 9y - 77 = 180° ( being linear pair)

12×8° - 28° + 9y -77° = 180°

96° - 28° + 9y - 77° = 180°

-9 + 9y = 180°

9y = 180° + 9°

y = 189°/9

Therefore, y = 21°

Therefore, X = 8° and y= 21° .

Hope it helps....
