Eliza cannot decide which of two bicycles to buy. The original price of each is $380. The first is marked down by 50%. The second is marked down by 30% with an additional 20% off. Part A: Find the sale price of each bicycle. Part B: Which bicycle should Eliza buy if the bicycles are the same except for the selling price?

Answer:

The coordinates of the vertices of ∆X′Y′Z′:

Step-by-step explanation:

Given the triangle △XYZ with the vertices

It is stated that △XYZ is translated up 3 units to form the image ∆X′Y′Z′.

Translating 3 units UP means we have to add 3 units to all the y-coordinates of the coordinates of the vertices X, Y, and Z to generate the image ∆X′Y′Z′.

Thus,

THE RULE OF TRANSLATING 3 UNITS UP:

P(x, y) → P'(x, y+3)

Therefore, the coordinates of the vertices of ∆X′Y′Z′ will be:

X(-4, 6) → X'(-4, 6+3) → X'(-4, 9)

Y(1, 6) → Y'(1, 6+3) → Y'(1, 9)

Z(1, 1) → Z'(1, 1+3) → Z'(1, 4)

Thus, the coordinates of the vertices of ∆X′Y′Z′:

Answer:

b

Step-by-step explanation:

According to the given angles in the question, angle b is greater than angle a.

Mathematical equations with inequalities on both sides are known as inequalities. In an inequality, we compare these two values as opposed to equations. Somewhere between, the equal sign is changed to a less than (or less than or similar to), bigger than (or greater or equal to), or just not equal to sign.

As per the given data from the question,

The side which has got a larger angle has the largest side.

The side c is greater than a and side b is also greater than a.

The remaining angle can be calculated as:

The sum of all angles will be equal to 360.

x + 75 + 90 + 105 = 360

x = 90°.

Answer:

UZ = 44

Step-by-step explanation:

3x+8 = 6x-28

36 = 3x

12 = x

UZ = 3(12)+8

UZ = 44

Answer:

I think UZ would be the same as ZS, so 6x - 28

Answer: = (-2,3)

Step-by-step explanation:

Here, fixed point = origin = (0,0)

Transformation rule for rotation of  [tex]90^{\circ}[/tex]counterclockwise about the origin:

[tex](x,y)\to (-y,x)[/tex]

Then, the image of the point (3,2) =  (-2,3)

Hence, the image of the point (3,2) after a rotation of  [tex]90^{\circ}[/tex]counterclockwise about the origin = (-2,3)

Answer:

(205-9x) times15

Step-by-step explanation:

The expression the total monthly revenue of Theodore and Sarah's business is  (205-9x)15.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Theodore and Sarah have a small business selling custom-made T-shirts. They currently sell 205 shirts per month and charge $15 per T-shirt. Sarah thinks they can increase their revenue by increasing their selling price, but Theodore knows from experience that each $1 increase in price will decrease the number of T-shirts they sell by 9 shirts per month.

The expression will be written as,

E = (205-9x)15.

Therefore, the expression the total monthly revenue of Theodore and Sarah's business is  (205-9x)15.

Step-by-step explanation:

Answer: 29

see in the picture, WX is the median of the trapezoid

=> WX = (ST + UV)/2

⇔ 7x + 8 = (10x + 5 + 8x - 1)/2

⇔ 7x + 8 = (18x + 4)/2

⇔ 7x + 8 = 9x + 2

⇔ 2x = 6

⇔ x = 3

with x = 3 => WX = 7.3 + 8 = 21 + 8 = 29
