Let's consider the first number to be 
and the second number to be 
. Based on the information in the problem, we can create the following equations:
Now, we can solve the equations through systems of equations. One way of doing this is by multiplying one of the equations so that there is a term in both equations which can be removed by addition or subtraction. In our case, we can multiply the entire first equation by 2 to get:
![2f + 4s = 2/tex][tex]2f + s = 14](https://tex.z-dn.net/?f=2f%20%2B%204s%20%3D%202%2Ftex%5D%3C%2Fp%3E%3Cp%3E%5Btex%5D2f%20%2B%20s%20%3D%2014)
Now, subtract 
from both equations to get:
Now that we have found , "plug" it back into an equation to find :
Our answers are s = -4 and f = 9.

Answer:
Step-by-step explanation:
Standard equation of a line is y = mx + b, where m is the slope.
Given line y = - 3x + 78, slope, m₁ = -3
<em><u>To find the line perpendicular to the given line.</u></em>
The lines are perpendicular to each other if the product of their slopes = - 1
That is,
So the slope of new line is
In general, the derivative of a single term Ax^(n) is A n x^(n-1) .
And the derivative of a sum of many terms is the sum of the derivatives
of the individual terms.
Using these two rules, the derivative (with respect to 'x') of the expression
in the question is . . .
<em> Y' = -21x² - 16x + 6</em>
Theoretical probablity=desiredoutcomes/totalpossibleoutcomes
desired=number of white marbles=20
total possible=red+blue+white=30+50+20=100
so theoretical probablity=20/100=2/10=0.2=20%
