  • A²+B²

The general algebraic identity is

  • A²+B²=(A+B)²-2AB

Lets derive

  • (A+B)²-4AB
  • A²+B²+2AB-2AB
  • A²+B²

Hence verified

A first number plus twice a second number is 1. Twice the first number plus the second totals 14. Find the numbers
poizon [28]

Let's consider the first number to be f and the second number to be s. Based on the information in the problem, we can create the following equations:

f + 2s = 1

2f + s = 14


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


Now, subtract 2f from both equations to get:

3s = -12

s = -4


Now that we have found s, "plug" it back into an equation to find f:

f + 2(-4) = 1

f - 8 = 1

f = 9


Our answers are s = -4 and f = 9.

One question simple please help
igor_vitrenko [27]

Answer:

y = \frac{1}{3}x - 9

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,

         m_1 \times m_2 = -1

So the slope of new line is

                                                   -3 \times m_2 = -1\\\\m_2 = \frac{-1}{-3} = \frac{1}{3}

Therefore , equation \ of \ new \ line \ \\\\(y - y_1) = m_2(x - x_1) , where \ (x_1 , y_1) = (9, -6 )\\\\(y - (-6))= \frac{1}{3}(x -9)\\\\y + 6 = \frac{1}{3} x - 3\\\\y = \frac{1}{3}x -3-6\\\\y = \frac{1}{3}x -9\\\\

Derivative of this function<br> <br>Y= -7X³ -8X² +6X +3
zaharov [31]

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>

A jar contains 30 red marbles 50 blue marbles and 20 white marbles what is the the theoretical probability of choosing a white m
svlad2 [7]
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%
