Answer:
Neither for 1
the second option for 2
Step-by-step explanation:
not sure how to explain this
Answer:
C+3
Step-by-step explanation:
The answer is A
1 1/2 *2 *1 1/2 = 4.5 or 4 1/2
Answer:
(-2+-5) equals -7.
Because the signs are the same, we dont change it.
(3+5) equals 8. Same like the other equation, the signs are the same so we do not change it.
Now we do (-7+8) The answer will be 1. Lets use a little graph since its hard to explain.
-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8
Mark -7 anyway you want. (Circle it, draw a line under it, what ever you want.)
Now Move the line 8 times.
When you do that your line will stop at 1.
And thats how you do it.

Answer:
Graph of Option D represents
Step-by-step explanation:
we are given our function as
squaring on both sides we get
It represent a parabola opening towards the positive side of x axis. Hence it gives us some preliminary idea about the graph of the function we are given .
However our original function is ![y=\sqrt{x}](https://tex.z-dn.net/?f=y%3D%5Csqrt%7Bx%7D)
Domain of
is all positive values of x
And square root of positive values will always result in positive values. Hence y can not be negative as the range is All positive values of y
Hence we erase the graph of
below x axis to obtain the graph of
![y=\sqrt{x}](https://tex.z-dn.net/?f=y%3D%5Csqrt%7Bx%7D)
