Check attachment.

6y = -2x - 6

y = -2/6x - 1

y = -1/3x - 1

It has a slope of -1/3 (going down)

The y intercept is -1

X-y=4 and 1/2x+1/2y=18

cluponka [151]

value of x = 20 and value of y=16

Solution set=(20,16)

Step-by-step explanation:

We need to solve system of equations:

$x-y=4\\\frac{1}{2}x+ \frac{1}{2}y=18$

Let:

$x-y=4\,\,\,eq(1)\\\frac{1}{2}x+ \frac{1}{2}y=18\,\,\,eq(2)$

Simplifying equation 2:

$\frac{1}{2}x+ \frac{1}{2}y=18$

Taking LCM on left side:

$\frac{x+y}{2}=18$

$x+y=18*2$

$x+y=36\,\,\,eq(3)$

Adding eq(1) and eq(3)

$x-y=4\\x+y=36\\-----\\2x=40\\x=40/2\\x=20$

Putting value of x in eq(1) and finding y:

$x-y=4\\20-y=4\\-y=4-20\\-y=-16\\y=16$

So, value of x = 20 and value of y=16

Solution set=(20,16)

Point K is rotated 90°. The coordinate of the pre-image point K was (2, –6) and its image K’ is at the coordinate (−6, −2). Find

aalyn [17]

Answer:

A clockwise rotation.

Step-by-step explanation:

The rule for 90 degree clockwise rotation is (x,y) turns into (y,-x) therefore if you use your numbers (2,-6) and then use the 90 degree clockwise rotation rule it becomes (-6,-2)

Each pitcher of podwer smoothie that Ginger makes has 2 scoops of pineapple,3 scoops of strawberries,1 scoop of spinach and 1 sc

WITCHER [35]

Answer:

She will use 49 scoops

Step-by-step explanation:

* Lets explain how to solve the problem

- Each pitcher of powder smoothie that Ginger makes has:

# 2 scoops of pineapple ⇒ 2 p

# 3 scoops of strawberries ⇒ 3 s

# 1 scoop of spinach ⇒ 1 sp

# 1 scoop of kale ⇒ 1 k

- She makes 7 pitchers of powder smoothies

* Lets write an expression for the number of scoops of one pitchers

powder smoothie

∵ 1 pitcher of powder smoothie contains 2 p scoops, 3 s scoops,

1 sp scoop and 1 k scoop

∴ The number of the scoops = 2 + 3 + 1 + 1 for one pitcher

∵ She makes 7 pitchers of powder smoothie

- Multiply the scoops of each type by 7

∴ The total number of scoops = (7 × 2) + (7 × 3) + (7 × 1) + (7 × 1)

- By multiply the numbers in the parentheses

∴ The number of total scoops = 14 + 21 + 7 + 7

∴ The number of total scoops = 49

* She will use 49 scoops
