Answer:

The values of x and y are x = 5 and y = -13 ⇒ B

Step-by-step explanation:

If the complex numbers are A = (a + bi) and B = (c + di), then

A + B = (a + c) + (b + d)i

Let us solve the question

∵ (x + yi) + (4 + 9i) = 9 - 4i

→ Add the real parts and the imaginary parts on the left side

∵ x, 4 are the real parts, and y and 9 are the imaginary parts

∴ (x + 4) + (y + 9)i = 9 - 4i

→ Compare the two sides, and equate the like terms

∵ 9 is the real part and -4 is the imaginary part

∴ x + 4 = 9

→ Subtract 4 from both sides

∴ x + 4 - 4 = 9 - 4

∴ x = 5

∵ y + 9 = -4

→ Subtract 9 from both sides

∵ y + 9 - 9 = - 4 - 9

∴ y = -13

Answer:

Step-by-step explanation:

The diagonals of a parallelogram cross at their midpoints. This means the segments of each diagonal are equal in length:

  RT = PT

  x = 5x -28

  28 = 4x . . . . . add 28-x

  7 = x . . . . . . . .divide by 4

  QT = ST

  5y = 2y +12

  3y = 12 . . . . .subtract 2y

  y = 4 . . . . . . divide by 3

The values of x and y that make the figure a parallelogram are x=7 and y=4.

Answer:

Perimeter: 52 Area: 181-16i?

Step-by-step explanation:

Perimeter

The formula for perimeter is 2l+2w, so you plug in the binomials they give you:

2(11-4i)+2(15+4i)

expand:

22-8i+30+8i

combine like terms (which cancels out 8i and -8i):

22+30=52

Area

"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.

Here's what I did to get 181-16i, in any case:

The formula for area is l*w, so I plugged in the numbers:

(11-4i)(15+4i)

expanded:

165+44i-60i-16i*i

and combined like terms:

181-16i

*i is [tex]\sqrt{-1}[/tex], so [tex]i^{2}[/tex]=-1 and -1*-16=16.

Answer:

12 hours

Step-by-step explanation:

Full time job:

Earning per week = $475

Part time job :

Earning per hour = $11

Number of working hours per week at per time job to increase weekly earning to atleast $600 ;

Let number of hours = h

Full time earning + earning per hour * (number of hours) ≥ 600

$475 + ($11 * h) ≥ 600

$475 + $11h ≥ 600

11h ≥ 600 - 475

11h ≥ 125

h ≥ 125 / 11

h ≥ 11.36

Hence, sharia will need to work for 12 hours per week

Answer: 321

Your explanation

There where 28 classrooms that donated. If we are to estimate the total, then we must round the canned items. They're 8982 canned items. If you round that number, you get 9000. So you want to divide 9000 and 28.

3x + 2y - 2x + y + 12 —> x + 3y + 12

4y + 3y + 3x - 6y - 10 -2 —> 3x + y - 12

12 - 3y - 2x + x + 2x —> x - 3y + 12

x + 3y + 2x - 3x + 7 + 5 —> 3y + 12

Answer:

The  slope-intercept equation having slope is '0' and intercept c= -11

  y = 0 x - 11

Step-by-step explanation:

Explanation:-

Given a point ( 0,-11) and has a slope  m= 0

The equation of the straight line

                   y - y₁ = m ( x-x₁ )

                  y - (-11) = 0 (x -0)

                    y +11 = 0

                       y = -11

Answer:

False

Step-by-step explanation:

A nonlinear function that can be written on the standard form

ax2+bx+c,wherea≠0

is called a quadratic function.

All quadratic functions has a U-shaped graph called a parabola. The parent quadratic function is

y=x2

picture51

The lowest or the highest point on a parabola is called the vertex. The vertex has the x-coordinate

x=−b2a

The y-coordinate of the vertex is the maximum or minimum value of the function.

a > 0                   parabola opens up                    minimum value

picture52

a < 0                    parabola opens down              maximum value

picture53

A rule of thumb reminds us that when we have a positive symbol before x2 we get a happy expression on the graph and a negative symbol renders a sad expression.

The vertical line that passes through the vertex and divides the parabola in two is called the axis of symmetry. The axis of symmetry has the equation

x=−b2a

The y-intercept of the equation is c.

picture54

When you want to graph a quadratic function you begin by making a table of values for some values of your function and then plot those values in a coordinate plane and draw a smooth curve through the points.

Example

Graph

x=x2+2x+1

Make a table of value for some values of x. Use both positive and negative values!

x y = x2 + 2x + 1

-3 4

-2 1

-1 0

0 1

1 4

2 9

3 16

Graph the points and draw a smooth line through the points and extend it in both directions

picture55

Notice that we have a minimum point which was indicated by a positive a value (a = 1). The vertex has the coordinates (-1, 0)  which is what you will get if you use the formula for the x-coordinate of the vertex

x=−b2a=−22⋅1=−1

and that the line has an y-intercept of (0, 1) which could have been determined from the c-value which is 1.

If you have an absolute value of a that is greater than 1 the parabola will be narrower than the parental quadratic function. And the opposite that if you have a absolute value of a that is less than 1 then the parabola will be wider than the parental quadratic function.

The vertical parabola opens downward, has its vertex in the fourth quadrant, and y = ax + bx +c is the equation of this parabola given conditions none of them is true.

A nonlinear function that can be written on the standard form

[tex]ax^{2} + bx +c = 0 where (a\neq 0)[/tex]

This called a quadratic function.

All quadratic functions has a U-shaped graph called a parabola. The parent quadratic function is'

[tex]y = x^{2}[/tex]

The lowest or the highest point on a parabola is called the vertex. The vertex has the x-coordinate .

x = −b2a

The y coordinate of the vertex is the value maximum or minimum of the function.

a > 0                   parabola opens up                    minimum value

a < 0                   parabola opens down     maximum value

A rule of thumb reminds us that when we have a positive symbol before we get a happy expression on the graph and a negative symbol renders a sad expression.

The vertical line that passes through the vertex and divides the parabola in two is called the axis of symmetry. The axis of symmetry has the equation

x = −b2a

The y-intercept of the equation is c.

When you want to graph a quadratic function you begin by making a table of values for some values of your function and then plot those values in a coordinate plane and draw a smooth curve through the points.

[tex]x = x^{2} +2x+1[/tex]

Make a table of value for some values of x. Use both positive and negative values!

This is the points lies on parabola

Answer:

Hi! The correct answer is y=5+x!

Step-by-step explanation:

~Add x to both sides of the equation~

Answer:

y = -5, x = 4

The value of a are; a = 6

Since Perpendicular lines have a slope that is negative reciprocal of each other. There product = -1

Solve both equations for y.

2x+3y=7                             x-8y=7

3y = ax + 7                                 8y = -4x + 2

y = ax/3 + 8/3                               y = -4x/8 + 2/8

y = a/3(x) + 8/3                              y = -1/2(x) + 1/4

Now we know that the slope;

y = -1/2(x)+ 1/4  is -1/2

Then the slope of y = a/3(x) + 8/3 is a/3.  

Now the value of "a" will make the lines perpendicular.

You know that one line slope is -1/2 so the other line slope is 2 because the slope are negative reciprocal.  

Thus remember that the slope is the coefficient of the x term.

Now   a/3 = 2 ; a = 6
