Answer:
C
Step-by-step explanation:
Can I get brainleist?
Answer:
No
Step-by-step explanation:
First picture:
You got the first two right (good job!), so I'll just tackle the third one. If you have to compute 
, it means that you have to substitute 
in place of 
. Differently from the first two points, this will generate a new function, rather than a specific value:
Second picture:
Given the point 
highlighted in the picture, you can deduce that the base is 
units long (since it spans from 
to 
) and the height is 
units long (because it spans from to ). So, the area of the rectangle is the multiplication between base and height:
But we know that 
, so we have
The domain of this function is given by the domain of the square root: we want its argument to be non, negative, so we have
But since the problem is symmetric, the answer is
You can only see the answer 
because, if you choose 
or 
, the rectangle degenerates to a segment, and your exercise doesn't like this scenario, apparently
<span>What is 3(6m) + m?
3(6m) + m =
m becomes 1m
9m + 1m =
10m
3(6m) + m is 10m when combining like terms. </span>
X = y - 8
Step by step
Y = x + 8
x + 8 = y
-8 -8
x = y - 8
