<u>answer</u>:

A. ( -1, 6), (0, 3), (1, 0), (2, -3)

<u>explanation</u>:

The x values fit the y values.

(a)

y = -3x + 3

y = -3(-1) + 3

y = 3 + 3

y = 6

(b)

y = -3x + 3

y = -3(0) + 3

y = 3

(c)

y = -3x + 3

y = -3(1) + 3

y = 0

(d)

y = -3x + 3

y = -3(2) + 3

y = -3

Answer:

$x=16\dfrac{28}{37}\\ \\y=5\dfrac{1}{3}\\ \\z=7.5$

Step-by-step explanation:

The diagram shows three paralel lines which divide the large triangle into three similar triangles.

By Thales theorem,

$\dfrac{5}{z}=\dfrac{y}{8}=\dfrac{2}{3}$

Then

$\dfrac{5}{z}=\dfrac{2}{3}\Rightarrow 2z=15,\ z=7.5\\ \\\dfrac{y}{8}=\dfrac{2}{3}\Rightarrow 3y=16,\ y=\dfrac{16}{3}=5\dfrac{1}{3}$

From the similarity of triangles,

$\dfrac{x}{20}=\dfrac{z+8}{z+8+3}\\ \\\dfrac{x}{20}=\dfrac{7.5+8}{7.5+8+3}\\ \\\dfrac{x}{20}=\dfrac{15.5}{18.5}\\ \\x=20\cdot \dfrac{155}{185}=20\cdot \dfrac{31}{37}=\dfrac{620}{37}=16\dfrac{28}{37}$

Tyler baked 702 cookies he sold them boxes of 18 after selling all of the boxes of cookies for the same amount each he earned 13

Sindrei [870]

Each box would be sold for $3.50 because 702 divided by 18 is 39, so he would have 39 boxes. $136.50 divided by 39 is $3.50.

If you have 8 cups of berries and it takes 2/3 cup to make a dessert how many desserts can you make?

Alik [6]

To find this we want to divide 8 cups by 2/3 cup per dessert.

To divide by a fraction, multiply the forst number by the reciprocal of the second.
(8/1)*(3/2)= 24/2
24/2=12

Final answer: 12 desserts
