Answer:

2) x - y =  \frac{2}{3}

=  > x =  \frac{2}{3}  + y =  \frac{2 + 3y}{3}

3) 3x + 2y = 6

=  > 3x = 6 - 2y

=  > x =  \frac{6 - 2y}{3}

4) \frac{1}{4} x + y = 2

=  > y = 2 -  \frac{x}{4}  =  \frac{8 - x}{4}

5) 4x - 3y =  - 33

=  >  3y  = 4x + 33

=  > y =  \frac{4x + 33}{3}

The area of the shaded region​
sweet-ann [11.9K]

Answer:

37.7

Step-by-step explanation:

Large circle = \pir² = \pi5² = 78.54

Medium circle = \pi3²= 28.27

Small circle = \pi2²= 12.57

78.54-28.27-12.57 = 37.7

39. Solve this system: 3x+y=-7 . 4x-y=14A. (–1, 10)B. (1, –10)C. (–1, –10)D. no solution
valkas [14]

Given,

The linear pair of the equation is,

\begin{gathered} 3x+y=-7 \\ 4x-y=14 \end{gathered}

Required

The solution of the linear equation.

Taking the equation first as,

\begin{gathered} 3x+y=-7 \\ y=-7-3x \end{gathered}

Substituting the value of y in second equation then,

\begin{gathered} 4x-y=14 \\ 4x+7+3x=14 \\ 7x+7=14 \\ 7x=7 \\ x=1 \end{gathered}

Substituting the value of x in first equation then,

\begin{gathered} 3x+y=-7 \\ 3(1)+y=-7 \\ y=-7-3 \\ y=-10 \end{gathered}

Hence, the solution of the system is (1, -10).

In the xy, y-plane, the parabola with equation y = ( x− 11)^2y=(x−11) 2 y, equals, (, x, −, 11, ), squaredintersects the line wi
IRINA_888 [86]

Answer:

10 units

Step-by-step explanation:

Allow me to revise your question for a better understanding.

<em>"In the xy-plane, the parabola with equation y = (x − 11) ² intersects the line with equation y = 25 at two points, A and B. What is the length of AB"  </em>

Here is my answer

Because the  parabola intersects the line with equation y = 25  Substituting y = 25 in the equation of the parabola y = (x - 11)², we get

25 = (x - 11)²

<=>x - 11 = ± 5  

<=> \left \{ {{x=6} \atop {x=16}} \right.

Thus A(16, 25) and B(6, 25) are the points of intersection of the given parabola and the given line.

So the length of AB = √[(16 - 6)² + (25 - 25)²]

= √100 = 10 units
