Step-by-step explanation:
Count from side to side. Point A to the arrow on the right, then point B to the arrow on the right, then point C to the arrow on the right, then point D, then point E. That's only one side, so double those five rays and you get ten (10). I was confused about this too at one point. You got this :)

Answer:
[tex] - (x - 1) {}^{2} + 5[/tex]
Step-by-step explanation:
F(x) is a transformation from h(x).
So our starting equation is
[tex] - (x - 1) {}^{2} - 1[/tex]
F(x) is also facing the same direction h(x) is so we dont have to reflect nothing across the x or y axis.
There isn't a vertical or horizontal stretch, compressions.
There isn't a horizontal shift as the x values stay in the same place.
There is a vertical shift. We can simply move h(x) up 6 units to get to f(x).
So our equation looks like.
[tex] - (x - 1) {}^{2} + 5[/tex]

If A D and C F, which additional statement does NOT allow you to conclude that AABC = ADEF?
Answer:
B
Step-by-step explanation:
i think its b because all the other answers are talking about the sides but b is talking about the angles which in the question it states angles (A,D,C, and F) so going off an educated guess i would say the answer is b i dont know if its correct or not though.
Dots sells a total of 290 T-shirts ($2) and shorts ($4) . In April, total sales were $678. How many T-shirts and shorts did Dots sell?
Answer:
241 t-shirt and 49 short
Step-by-step explanation:
lets call shorts x and tshirts y
x+y=290 (first equation)
4x+2y=678 (second equation) { we multiply the price of short with the short so we can get the pieces sold and also with the t-shirt to get the pieces sold)
x=290-y
and substitute it with x in the second equation
4(290-y)+2y=678 then till u get to y=241 (the pieces sold)
290-241=49 (pieces sold)
so as proof 49+241=290 pieces sold
as proof also 4*49=196 price of all shorts sold
2*241=482 price of all t-shirts sold then add them together and u will get 196+482=678$

Taylor noticed that for the rectangle below she could multiply 2 times 3 to get its area of 6 square inches. How else could she find the area?
Answer:
Add 2+2+3+3
Step-by-step explanation:
Correct me if i'm wrong but that's my answer. I studied this 3 years ago.
Answer:
3 x 2 or 3 + 3
Given: Taylor noticed the rectangle she could multiply 2 times 3 to get its area of 6 square inches.
so, if we did 3 times 2 its 6 but if we did 3 + 3 it also 6 so therefore she could do 3 x 2 or 3 + 3 to find the area.
Step-by-step explanation:

A salesperson earns a base salary of $32,500 per year plus a commission of 8% on total sales. Her total sales for one year were $450,000. Find the salesperson's total pay for the year.
The salesperson's total pay for the year is $68500
How to determine the total pay?The given parameters are:
Base pay = $32,500
Commission = 8%
Total Sales = $450,000
The total pay is calculated as:
Total = Base pay + Commission * Total Sales
This gives
Total = $32,500 + 8% * $450,000
Evaluate
Total = $68500
Hence, the salesperson's total pay for the year is $68500

Step-by-step explanation:
A shape is made of 9 right triangles of equal size and three identical rectangles.
Each rectangle measures 7 mm wide by 3 mm high. The rectangles are each
7 mm wide by 3 mm high. What is the total area, in square millimeters,
of the shape?
Answer:
The area of the figure is 157.5 square millimeters.
Step-by-step explanation:
Since a shape is made of 9 right triangles of equal size and three identical rectangles, and each rectangle measures 7 mm wide by 3 mm high, while the rectangles are each 7 mm wide by 3 mm high, to determine what is the total area, in square millimeters, of the shape, the following calculations must be performed:
Area of a rectangle: base x height
Area of a triangle: (base x height) / 2
7x3 = 21 = Rectangle area
7x3 / 2 = 10.5 = Triangle area
21 x 3 + 10.5 x 9 = 157.5
Thus, the area of the figure is 157.5 square millimeters.
