18 is __% of 30
I am Lyosha [343]

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:

c < \frac{9}{8}

For all c less than \frac{9}{8} ,the given quadratic equation has no real number solutions.

Step-by-step explanation:

Given

Quadratic Equation

-2x^{2} + 3x + c = 0

On comparing with general form of Quadratic Equation

Ax^{2}+ Bx + C = 0

we have,

A=-2\\B=3\\C=c\\

For no real number solution we must have

Discriminant, B^{2}- 4AC < 0\\(3)^{2} - 4\times -2\times c < 0\\9-8c < 0\\-8c < -9\\c < \frac{9}{8}

So, For all c less than \frac{9}{8} ,the given quadratic equation has no real number solutions.

Can someone help i have been asking for 2 hours
yawa3891 [41]

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).

a 15% tip to represents the ratio $0.15 to 100 cents. why does this make 15 percent a unitless Factor
DochEvi [55]
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.

What is X-3y=9 in slope intercept form and the equation
ivann1987 [24]
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
