Hey there,
Your question states: <span>These are 2-dimensional shapes. They are made of straight lines, and the shape is “closed” (all the lines connect).
</span><span>The correct answer would be Polygon. Polygons are the shapes with a </span> 2-dimensional shapes, and has straight lines.

Sinα=cos(90-α) this is an identity which you need to know...
in this case:
sin49°=cos41°
Your answers are wrong. the function f(x) is like a factory. you put in something ( a number) and it will spit you out something else (a different number depending on the function). your function, f (x)= -2x+1
you can put anything in that function. let say k.
f(x=k) = -2k+1. you just replace the x with k.
in this particular problem they way f(-2) ,f(0), f(1) and f(2).
here are the results
f(x=-2) = f(-2) = -2×(-2)+1 =5
f(x=0) = f(0) = -2×(0)+1 =1
f(x=1) = f(1) = -2×(1)+1 =-1
f(x=2) = f(2) = -2×(2)+1 =-3
Answer:
Slope is 2 and y-int is -6
Step-by-step explanation:
y=mx+b
M is slope
B is y-int
Answer:
it’s b.
Step-by-step explanation:
(6)^2+(8)^2is not equal to (11)^2
