A percent is just a fraction.
So take your two numbers and make a fraction with them ... 18/30 .
18 is 18/30 of 30 .
Now, to find the percent that's equivalent to 18/30 ,
first do the division:
18/30 = 0.6 .
Now, to change a decimal into percent,
move the decimal point two places that way ==> .
0.6 = 60% .
18 is 60% of 30 .
Answer:

For all c less than
,the given quadratic equation has no real number solutions.
Step-by-step explanation:
Given
Quadratic Equation

On comparing with general form of Quadratic Equation

we have,

For no real number solution we must have

So, For all c less than
,the given quadratic equation has no real number solutions.
Flipping a point across the y axis, the y coordinate should flip signs (negative if it was positive before, and vice versa). So
reflection across y axis = (-1 5/7, 1).
Similarly, reflecting across the x axis, the sign will also flip. So
reflection across x axis = (1 5/7, -1).
We don't assume that 15% is 15% of some number of cents - it's just 15/100. In the given example, we have 15 cents divided by 100 cents. We can remove the cents from both the numerator and the denominator to get 15/100, which has no units.
The slope intercept form would be y= 1/3x -3
First, you add 3y to each side
That cancels out the -3y on the left side of the equation and adds a +3y to the right
Now you have x = 3y + 9
Subtract 9 from each side and now you have
3y = x - 9
Now all you have to do is divide 3 from each side
3y divided by 3 = y
x divided by 3 = x/3 or 1/3 x
-9 divided by 3 = -3
The end result is y = 1/3x - 3
