Answer:
The function is shown by the graph below ⇒ 2nd answer
Step-by-step explanation:
<em>To find the right function chose two points from the graph and substitute the x-coordinate of each point in the function to find the y-coordinate, if they are the same with the corresponding y-coordinates of the points, then the function is shown by the graph</em>
From the figure:
The curve passes through points (-2 , 0) and (2 , 2)
∵
∵ x = -2
- Substitute x by -2
∴
∴ ⇒ it is impossible no square root for (-) number
∴ is not the function shown by the graph
∵
∵ x = -2
- Substitute x by -2
∴
∴
∴ f(-2) = 0 ⇒ same as the y-coordinate of x = -2
∵ x = 2
- Substitute x by 2
∴
∴
∴ f(2) = 2 ⇒ same as the y-coordinate of x = 2
∴ The function is shown by the graph below
Answer:
10 hours
Step-by-step explanation:
If I have $50 in my bank account, and I want to have a total of $130 in my account. It means that I need to work enough hours to make $130 - $50 = $80.
If I make $8 per hour, and I need to make $80, then I just have to work 10 hours. ($80/8 = 10)
Answer:
I think the answer is 56
Step-by-step explanation:
35 divided by 5 is 7, then you multiply 7 by 8 and you get 56
1.) 52:97.5
2.) 1:1.875
Hope this helps!
Answer:
The third figure is the answer (Look to the attached figure
Step-by-step explanation:
* The point of symmetry means
- If a figure or graph can be rotated 180° about a point P
and end up looking identical to the original, then P is a point
of symmetry
- The same distance from the central point
but in the opposite direction.
* Lets look to the four answers
- In the 3rd figure first line up can be rotated 180° about a point P
and end up looking identical to the second line down, then P
is a point of symmetry
- The same distance from the point p
but in the opposite direction.
* The figure show the answer
