The rule for the reflection is (x,y,z) → (-x,y,z) so P' = (1, 2, 0) for example. 
<span>Then the rule is (x,y,z) → (x + 2, y + 4, z - 3) so P'' = (3, 6, -3) </span>

Rocco spent 20% of his savings on clothes. He brought $50 clothes. How much did he have in the beginning
Anna71 [15]
Howdy,

20% is also 1/5 in fraction form, which tells us he spent 1/5 of his money on clothes:

So to solve, we have to multiply 50 by 5:

50 x 5 = 250

Rocco's original savings was $250

Hope this helps! <span />

The equation y-2= 5/4 (x + 8) represents the cost (in dollars) of making your own fruit juice (fluid ounces) a. What is the slop
LekaFEV [45]

Answer:

a. The slope is 5/4

b. The equation in slope and intercept form is y = 5/4·x + 12

c. The base cost of making a fruit juice is $12

Step-by-step explanation:

The equation that gives the cost in dollars of making your own fruit juice is given as follows;

y - 2 = 5/4·(x + 8)

a. The slope = The coefficient of x = 5/4

The slope = 5/4

b. The equation can be presented in slope and intercept form, y = m·x + c, as follows;

y - 2 = 5/4·(x + 8)

y = 5/4·x + 10 + 2

y = 5/4·x + 12

c. The base cost of making a fruit juice = The cost added to any quantity of fruit, x made = The y-intercept, c = 12

The base cost of making a fruit juice = $12.
