Answer:
7-2x
Step-by-step explanation:
7-10x/5
If it was 10x/5 then it becomes 2x
7-2x
but if was dividing 7-10x by 5 then it would just be 7-10x over 5
Hope this helps :)
I think it is 1742.35. I got that by doing 1724.53 x 0.4 x 3.1%. You add that to 1724.53.
Answer:
Option 3
Step-by-step explanation:
we are given the graph of a parabola
with vertex at (0,-1) and symmetrical about y axis and also open up.
Hence the equation of the graph would be transformation of
by a vertical shift of 1 unit down.
So new equation after transformation would be
Or
Hence option 3 is right choice.
Verify:
Put Solving the equation we get
In the graph x intercepts are the same as -1 and 1
Hence our answer is right.
