<span>2x-y = -4 OR y = 2x+4
-3x+y=44
-3x + (2x+4)= 44

-x = 40
x = -40 and y = -76 (2*-40 + 4)
c-5d=2 OR c = 5d + 2
2c + d =4
2(5d+2) + d = 4
11d = 0
d = 0 and c = 2 </span>

Sandy has 16 roses, 8 daisies, and 32 tulips. She wants to arrange all the flowers in the bouquets. Each boquet has the same num
natima [27]
Your answer would be 8 since that is your least common denominator between the three bouquets.
If it was more than 8 then each bouquet wouldn't have the same number of flowers since you only have a total of 8 daisies.

The length of a rectangle is 2 meters less than 2 times the width. The perimeter is 20 meters. Find the width.
kakasveta [241]
The equation you'd make would be (2x-2)+(2x-2)+x+x=20 because the length is 2 m less than the width (x). To simplify, it'd be 6x-4=20 because you combine like terms. You then move the -4 over to the 20 to make it 6x=24. The final answer is 4 meters.

URGET PLEASE HELP QUICKLY
alexdok [17]

Answer: -0.5.

Step-by-step explanation:

The constant of variation k for the direct variation is given by:-

k= \dfrac{f(x_2)}{x_2}=\dfrac{f(x_1)}{x_1}

The given table:

x  f( x )

0   0

2   -1

4    -2

7   -3.5

Then,

k=\dfrac{-1}{2}=\dfrac{-2}{4}=\dfrac{7}{-3.5}=-0.5

Hence, the constant of variation k for the direct variation is -0.5.
