Mathematics

Masja [62]3 years ago

Answer:

x=5, y=6. (5, 6).

Step-by-step explanation:

-6x+6y=6

-6x+3y=-12

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

simplify -6x+6y=6 into -x+y=1 and y=1-(-x)=1+x

-6x+3(1+x)=-12

-6x+3+3x=-12

-3x=-12-3

-3x=-15

3x=15

x=15/3

x=5

-6(5)+6y=6

-30+6y=6

6y=6-(-30)

6y=6+30

6y=36

y=36/6

y=6

Consider the system of equations.
anzhelika [568]

Answer: You can multiply the top equation by -1 to eliminate the x variable.

And the solution is (2,4/3)  in case you need it.

Step-by-step explanation:

2x + 3y = 8

2x + 6y = 12

If you multiply the upper equation or down equation by one, you will be able to eliminate the x variable.

-1( 2x + 3y) = -1(8)     New equation:   -2x -3y  = -8.

Add the new equation you got  by multiplying the top equation by -1 to the bottom equation.

Add them:     -2x -3y = -8

                      2x + 6y = 12  

                               3y = 4  

                              y = 4/3

You can now input the value for y into the one of the equations and solve for x.

-2x - 3(4/3) = -8

-2x -4 = -8  

     +4     +4

-2x = -4

x = 2

What is a possible value of sin(theta) when cos2(theta)=0.73?
Sindrei [870]
We use the following trigonometric identity to answer the question:
 sin^ 2 (theta) + cos^ 2 (theta) = 1
 We substitute the values:
 sin ^ 2 (theta) + 0.73 = 1
 We cleared:
 sin ^ 2 (theta) = 1-0.73
 sin ^ 2 (theta) = 0.27
 Answer:
 a possible value of sin ^ 2 (theta) is:
 
c.0.26 (nearest option)
