Y = mx + b
slope(m) = -3
(2,7)...x = 7 and y = 2
now we sub and fund b, the y int
2 = -3(7) + b
2 = -21 + b
2 + 21 = b
23 = b <== ur y int
M or slope: 2
B or y intercept: 7
Equation: y=2x+7
I think this is right Srry if it’s wrong
<span>The apothem is the distance from the center to the midpoint of a side. You can make a right triangle out of the apothem, half a side, and a line from the center to the corner. Its base is half a side so 13.5 and its height is 32.6. The area of the triangle is 13.5*32.6*1/2 = 220.05. There are 16 of these triangles in the octagon (2*8). 220.05*16 = 3520.8.</span>
You should use part/whole = %/100 and cross multiply. So you will get 20/x = 80/100 (whole is x because we are trying to find what whole is). now you will have 2000=80x. Now you divide 2000/80 and get 25=x. So, there are 25 costumes in total which means they need to make 5 more.
Step-by-step explanation:
the answer is true
