Answer:
a) yes b) no c) no
Step-by-step explanation:
In order to know this, remember something: to do the division between a number and a rational number like this and with zero to the left, the best way to solve them is converting these number to a natural number.
To do that, you only need to multiply the number by 10, 100, 1000, depending of how many decimals it have.
In case a) 0.05 has two decimals, therefore we multiply by 100:
0.05 * 100 = 5
However, when you do that, you have to do the same thing with the number in the dividend, in this case, 1.4:
1.4 * 100 = 140
So we can conclude that 1.4 you have to add a zero to do the division.
Case b) and c) do not apply, in both cases we multiply by 10 and we get this:
25.2 and 6,
26.1 and 3.
15.5% is the same as 15.5/100 or 155/1000, which you can take a 5 out of.
After that, you will get 31/200
5x^2+6=f(x)
and your graph plug that equation into an graph creator and it will automaticlly make your graph
