Sarah sells fruit trays at a salad shop. Last week, she sold 450 fruit trays for $8 per tray. In previous weeks, she found that

for every $0.85 increase in the price, she sold 15 fewer fruit trays. Which equation can be used to find Sarah's weekly sales income in dollars, y, after x price increases of $0.85?

Sarah's income = Number of trays × Rate per tray

y = 450 × 8

If there is an increase of 0.85 in price,

New price = 8 + 0.85

For x number of increases,

new price = 8 + 0.85x.

Number of trays reduced = 450 - 15x.

So, Sarah's income in this case is y = (450 - 15x) (8 + 0.85x).

X - 3= -21 <br>This is so confusing:(​
Aneli [31]

Answer:

\huge\boxed{x=-18}

Step-by-step explanation:

In order to solve this, we are trying to find the value of x. Basically, x is a placeholder for a number that is unknown. Some number minus 3 is equal to 21.

Our goal is to find x. To do this we want to isolate x on one side of the equation

x-3=-21

Let's add 3 to both sides.

x-3 + 3 = -21+3\\\\-3 + 3 = 0\\\\x = -21+3\\\\x=-18

Hope this helped!

Given angle ABC shown on the coordinate plane below.
Crank

The attached image shows the image of A"B"C" after the transformation

<h3>What is the transformation of the triangle about?</h3>

The transformation rule states:

A"B"C" = Ro90° (T(-4,3)(ABC))

This implies that one need to rotate the triangle in a 90⁰ clockwise direction, and then one need to translate the triangle.

Using the image shown, the coordinates of ABC are;

A = (-1, 2)

B = (1, 4)

C = (3, -1)

The 90⁰ rule clockwise rotation  will be:

(x,y) -- (y,-x)

So, when translated, it will be:

A' = (2, 1)

B' = (4, -1)

C' = (-1, -3)

Then the translation of the triangle using T(-4,3):

(x, y) -  (x - 4, y + 3)

So, there is:

A'' = (-2, 4)

B'' = (0, 2)

C'' = (-5, 0)
