Answer:

x = -2

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtraction

~

First, subtract 7 from both sides of the equation:

6x + 7 = -5

6x + 7 (-7) = -5 (-7)

6x = -5 - 7

6x = -12

Next, isolate the variable, x, by dividing 6 from both sides of the equation:

(6x)/6 = (-12)/6

x = -12/6

x = -2

x = -2 is your answer.

Step-by-step explanation:

This is late but the other is not an answer at all.

The 50 ft string makes an angle of 39 degrees with the ground so the stromg and balloon form a right-angle triangle to the ground.

The height of balloon from string = 50*sin(39degrees)

= 31.47 ft

As the string is held by a person 5 ft above ground, the balloon is above ground at 31.47 + 5

= 36.47 ft.

The width of the sidewalk is 1.155.

A rectangle is a type of parallelogram having equal diagonals.

All the interior angles of a rectangle are equal to the right angle.

The diagonals of a rectangle do not bisect each other.

Given that,

The dimension of the rectangular garden is  8 x 6.

The surface of the new garden is 1/6 th of the original one.

Suppose the width of the side walk is x.

Then, the dimensions of the sidewalk is given as (8 - 2x)  x (6 - 2x).

As per the question the following equation can be written for the area of new garden,

(8 - 2x)  x (6 - 2x) = (1/6) (8 x 6)

=> 48 - 4x²- 30x = 8

=> 4x² + 30x - 40 = 0

Solve the above quadratic equation to get,

x = -8.655, 1.155

Since the width cannot be negative, the value of x is taken as 1.155.

Hence, the width of the sidewalk of the new garden is 1.155m.

Answer:

10/3

Step-by-step explanation:

The graph of the equation, y = 4x, is shown below.

Given an equation, for example, y = 4x, to plot it on a coordinate plane, we need to find the coordinates of the line that we would plot and connect together to graph the equation.

Find the corresponding y-values when x = 1, x = 2, and x = 3. To do this, see the steps below:

Substitute x = 1 into y = 4x:

y = 4(1)

y = 4

We have a point, (1, 4).

Substitute x = 2 into y = 4x:

y = 4(2)

y = 8

We have another point, (2, 8).

Substitute x = 3 into y = 4x:

y = 4(3)

y = 12

We have a third point, (3, 12).

Plot the three points on a coordinate plane as shown below to get the graph of the equation.

In order to get J(x) = D(x) we need to make right sides equal and solve for x:

Problem 1

w = width

w+36 = length, because it's 36 feet longer compared to the width

=======================================================

Problem 2

The area w(w+36) is less than 2040, and it's also larger than 0.

We can write that as [tex]0 \le w(w+360) \le 2040[/tex] which is the same as [tex]0 \le w^2+360w \le 2040[/tex]

If you wanted to drop the first part, then you can say either [tex]w(w+360) \le 2040[/tex] or [tex]w^2+360w \le 2040[/tex]

I used the formula area = length*width

=======================================================

Problem 3

There are many possibilities here. Let's say w = 10 feet. If so then the length would be w+36 = 10+36 = 46 feet. This 10 by 46 rectangle has an area of 10*46 = 460 square feet which is under the 2040 sq ft limit.

Another possibility is that w = 20 ft and w+36 = 56. This 20 by 56 rectangle has an area of 20*56 = 1120 sq ft.

It turns out you can pick any value of w between 1 and 30, assuming you only restrict yourself to integers. You can find the largest possible value of w by solving the equation w(w+36) = 2040. The positive solution to this equation is roughly w = 30.62

Side note: even though something like w = 1 is possible, it's not very realistic. A conference hall that's only 1 ft wide won't be able to fit a person comfortably unless they don't mind being sandwiched between two walls and have to walk sideways.

=======================================================

Problem 4

If you solved w(w+36) = 360 with a graphing calculator or the quadratic formula, then you would find the positive solution for w is roughly 8.15

If your teacher is considering positive real numbers, then this is realistic; however, if they are only considering positive integers, then something like w = 8.15 isn't possible.

Answer:

[tex]y = \frac{1}{4} x - 11[/tex]

Step-by-step explanation:

Slope- intercept form

y= mx +c, where m is the slope and c is the y-intercept.

Slope

= 0.25

= ¼

Substitute m= ¼ into the equation:

y= ¼x +c

Given that the y-intercept is -11, c= -11.

Thus, the equation of the line is y= ¼x -11.
