Answer:
80 square units
536.6
Step-by-step explanation:
First one.
2 Trapezoids
A =
x h
A =
x 2
A = 16
One rectangle
A = b x h
A = 6 x 8
A = 48
Total Area = 16 + 16 + 48 = 80
Second one:
Two triangles:
A =
A = 
A =
A = 43.3
One large rectangle
A = b x h
A = 30 x 15
A = 450
Total Area = 450 + 43.3 + 43.3 = 536.6
Answer:
C
Step-by-step explanation:
Rather than picking, let's try to construct one from the description.
reflected over the x axis means -
the vertex is usually at (0,0), now how do we move a graph? or in other words translating it.
To move left and right you use
where if you subtract h you move right and if you add h you move left. we go from (0,0) to (-4,2). so 0 to -4 is 4 left, so that means we add 4.
To move up and down we use
Here if v is positive you move up and if v is negative you move down. going from (0,0) to (-4,2) it moves up 2
So now we put them all together
And if you look, C matches that exactly.
Answer:
One solution (-1,2)
Step-by-step explanation:
Since these two linear equations have different slopes, different y-intercepts, and are indeed linear, these equations will only have one crossing when graphed, and hence one solution.
To find that solution, we can simply set the equations equal to each other.
y = -x + 1
y = 2x + 4
-x + 1 = 2x + 4
-3 = 3x
-1 = x
Now plug that value back into one of the equations:
y = -x + 1
y = -(-1) + 1
y = 2
So now you know the crossing for these two equations occurs at (-1,2).
Cheers.
Answer:
25
Step-by-step explanation:
it's because 5 is squared so 5x5 is 25 and x squared
