Answer:

Solution is

(\frac{1}{2},\frac{-3}{2})

Which is Option C

Step-by-step explanation:

We are given the equations

4x - 6y = 11                     ...............(i)

3x+y = 0                         ..............(ii)

Now from equation (ii) we have

3x + y = 0

subtracting 3x from both sides we get

3x + y - 3x = 0 - 3x

y = -3x                       ....................(iii)


substituting this value in equation (i) which is

4x - 6y =11

Putting the value of y

4x - 6(-3x) = 11

4x + 18x = 11

22x = 11

Dividing both sides by 22

we get

\frac{22x}{22}=\frac{11}{22}

or

x=\frac{1}{2}

Now we have equation (iii) which tells us that

y= -3x

Putting value of x here

y = -3(\frac{1}{2})

It becomes

y = \frac{-3}{2}

So

Solution set of the equation is

(\frac{1}{2},\frac{-3}{2})

7. When dy/dx = (x -6)1/2, what does y equal?
Sergio039 [100]
The answer is below
\frac{dy}{dx} = \frac{1}{2} (x - 6)
multiply both sides by dx

dy = \frac{1}{2} (x - 6)dx
integrate both sides of the diffrential

integral \: dy = integral \: \frac{1}{2} (x - 6)dx
simplify and integrate to get y alone don't forget to tack on c with your indefinite integral

y = \frac{x {}^{2} }{4} - 3x + c

Find the area of this irregular figure. Please explain in steps how you did it so I know how to do it for the next question plea
Helen [10]
<h3>Answer:   426 square feet</h3>

Work Shown:

A = area of the rectangle

A = length*width

A = 26*15

A = 390 square feet

B = area of the triangle

B = base*height/2

B = 8*9/2

B = 72/2

B = 36 square feet

C = total area

C = A+B

C = 390+36

C = 426 square feet
