Answer:

x = 1 , x = 13

Step-by-step explanation:

(x - 7)² = 36 ( take square root of both sides )

x - 7 = ± [tex]\sqrt{36}[/tex] = ± 6 ( add 7 to both sides )

x = 7 ± 6

then

x = 7 - 6 = 1

x = 7 + 6 = 13

After making and solving an equation, we can say that the value of x is 1.

So, to find the value of x, we will solve the equation:

7(x/9) + 2 = 25/9

Now, solve this equation as follows:

7(x/9) + 2 = 25/9

7x/9 = 25/9 - 2

7x/9 = 7/9

x = 1

Therefore, after making and solving an equation, we can say that the value of x is 1.

Answer:  "If my bill is not expensive. I did not use my cell phone too much"

Reason:

The original statement is of the form "If P, then Q"

P = "I use my cell phone too much"

Q = "my bill will be expensive"

An equivalent form to the original condition is known as the contrapositive of the form "If not Q, then not P". We swap the positions of P and Q. We also negate each part. You can use a logical truth table to verify that the conditional and contrapositive have equivalent truth values, which means they are effectively equivalent statements.

The other wall is 12 feet long can be evaluated using Pythagoras theorem.

What is Pythagoras theorem?

The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC2 = AB2 + AC2 in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.

Here given in the question that one side of the wall 5 feet

So as it is a rectangular bedroom it can be split into 2 right-angled triangles.

So the hypotenuse of the triangle is 13 feet

Now using the Pythagoras theorem we can  find out the length of the other wall

b²=h²-p²

b²=13²-5²

b²=169-25=144

b=√144

b=12 feet

Hence the other wall is 12 feet long.

Given: An objective function

with constraints-

Required: To graph the linear inequalities representing the constraints and determine the objective function's value at each corner.

Explanation: The inequalities can be graphed by considering them as equations and then determining the shaded region by less than or greater than symbol.

The equation for the first inequality is-

This represents a straight line passing through points (6,0) and (0,12).

The shaded region will be below this line as the inequality is-

Similarly, the inequality-

Represents a shaded region above the line x+y=6.

The inequalities-

Represents the positive values of x and y. Hence we need to determine the graph in the first quadrant.

The graph of the inequalities is-

The graph in blue represents the inequality-

While the graph in green represents the inequality-

The corner points of the common shaded area are A(0,6), B(0,12), and C(6,0).

Now the value of the objective function at these points is-

a) At A(0,6)

b) At B(0,12)

c) At C(6,0)

Final Answer: a) The graph is drawn.

b) 36,72,18

The results of the transformations carried out are respectively;

1) Preserves only angles but not distance

2) Preserves both angles and distance.

3) Preserves only angles but not distance

In transformations, there are different types such as dilation, reflection, translation, rotation, e.t.c

1) Dilation of a quadrilateral by a scale factor of 2;

When we dilate by a scale factor of 2, it simply means we are enlarging the side lengths by a scale factor of 2. Thus, the side lengths will increase but angles remain the same.

2) Translation of a rhombus 3 units to the right and then a reflection across the x-axis;

When we translate an object, it means we just move it from one point to the other and this means that the length and angles do not change, Similarly, reflection is just a mirror image and it also means that the length and angles do not change.

3) Translation of a triangle 2 units to the left and then a dilation by a scale factor of 5 about the origin;

This will end up changing the side lengths but not the angles.

The system of equations we have is:

And we need to check if the point (3,-1) is a solution.

Step 1. Identify the values of x and y from the point.

In a point, the first number represents the x-value, and the second number represents the y-value. So in point (3,-1) 3 is the x-value, and -1 is the y-value:

Step 2. Substitute the x and y-value into the first equation and check that the result is equal to -7.

The first equation is:

Substituting x=3 and y=-1:

Solve the operations:

Since we get -7 as the result, (3,-1) is a solution for the first equation. But we still need to check if the point is a solution for the second equation.

Step 3. Substitute the x and y values into the second equation and check that the result is 1.

The second equation of the system is:

Substituting x=3 and y=-1:

Solving the operations:

The result we get is -1, not 1. Thus, since the point (3,-1) is not a solution for the second equation, it is also not a solution to the system of equation.

What is the independent and dependent variable?

An independent variable is a variable that does not depend on any other variable.

For example,

x is an independent variable because for every value of x, there is a different value of y

A dependent variable is a variable whose value depends upon an independent variable.

For example;

From the expression above, the value of y depends on the value of x

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A box of fruit has four times as many oranges as grapefruit.

And, Total number of fruit = 60 pieces

Now,

Let number of grapefruit = x

Then, Number of Mangoes = 4x

So, We can formulate;

⇒ x + 4x = 60

Solve for x as;

⇒ 5x = 60

⇒ x = 12

Thus, Number of grapefruit = x

                                          = 12

Then, Number of Mangoes = 4x

                                          = 4 × 12

                                          = 48

Such that b ≠ -2.

We know that a general linear equation is written in the slope-intercept form as:

y = m*x + b

Where m is the slope and b is the y-intercept.

We know that two linear equations are parallel if and only if the lines have the same slope and a different y-intercept.
