First you regroup the terms .
-15 - 15i = 15
Since -15i - 5i = 15 is false , there is no solution

Answer:

i= -6

Step-by-step explanation:

-5i-15=15

if we use inverse operation here, it would be -5i=30, so i= -6

Answer: 1/24

---------------------------------------------------------------------
---------------------------------------------------------------------

Work Shown:

A = selects green pair of shorts
B = selects gray t-shirt

P(A) = probability of selecting green shorts
P(A) = (number of green shorts)/(number of shorts total)
P(A) = 1/6
P(B) = probability of selecting gray t-shirt
P(B) = (number of gray t-shirts)/(number of t-shirts total)
P(B) = 1/4

P(A and B) = probability of selecting green shorts AND gray t-shirt
P(A and B) = P(A)*P(B) ... since A and B are independent events
P(A and B) = (1/6)*(1/4)
P(A and B) = (1*1)/(6*4)
P(A and B) = 1/24

Note: The fraction 1/24 is approximately equal to 0.041667

Total = 10W+14R

probability of red = R/total

10+14 = 24 so total = 24

R = 14

14/24

reduce (divide by two on the top and bottom)

14/2

How do I find the Axis of Symmetry for a parabola
soldier1979 [14.2K]

Answer:

Explanation given below.

Step-by-step explanation:

The first step is to put the parabola in the form  ax^2+bx+c , which is the <em>standard form of a parabola</em>

<em />

<u>Note:</u> a is the coefficient before x^2 term, b is the coefficient before x term, and c is the independent constant term

The axis of symmetry divides the parabola symmetrically. The axis of symmetry has the equation  x=-\frac{b}{2a}

Where <em><u>a and b are the respective values shown above</u></em>

<em><u /></em>

So, that is how you get the axis of symmetry of any parabola.
