2.Solve the inequality for x. Show each step to the solution.12x > 3(5x – 2) – 15

Answer:

C is correct.

Step-by-step explanation:

The area of the rectangle is 10 × 6, or 60 square meters.

The area of the triangle is 1/2 × 7 × 6, or 21 square meters.

So the area of the shaded region is the area of the rectangle minus the area of the triangle. That area is 60 - 21, or 39 square meters. C is correct.

We know that the multiplication of both sides of the rectangle is the area of it.

In this case

• The path is 3 miles long.

• Amber's goal is 4.5 miles a day.

To find the number of times she will walk around the park, we have to divide.

she already had 44 photos

She took 24 photos each day for 6 days.

The function is:

y= 44+24x

where y is the total number of photos and x is the number of days.

The initial value is when x=0

y= 44+24(0) =44

The value of ∠K is 46.2° as the definition of angle is "An angle is created by joining two line segments at one point, or we can say that an angle is the combination of two line segments at a common endpoint".

An angle is created by joining two line segments at one point, or we can say that an angle is the combination of two line segments at a common endpoint. When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the word "angle" originates. Based on measurement, there are different kinds of angles in geometry. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation. A geometrical shape called an angle is created by joining two rays at their termini. In most cases, an angle is expressed in degrees.

Here,

Side i = 68.91521 cm

Side j = 66 cm

Side k = 53 cm

Angle ∠I = 69.8°

Angle ∠J = 64°

Angle ∠K = 46.2°

∠K= sin⁻¹(k·sin(J)/j)

=sin⁻¹(53.(sin 64°)/66)

=46.2°

Since the definition of an angle is "An angle is created by joining two line segments at one point, or we can say that an angle is the combination of two line segments at a common endpoint," the value of ∠K is 46.2°.

The equation of the line which represents the given graph is -3x + 6y = 36

We can infer from the graph that the equation of the line passes through the points (0,6) and (-12,0).

Therefore the slope of the line passing through these two points is given by:

m = (0-6)/(-12-0)

or, m = 1 / 2

Now we can use the general equation of the line to get the required equation.

y-6 = 1/2 (x-0)

or, 2y - x = 12

Now we will multiply throughout by 3 we get:

6y - 3x = 36

or, -3x + 6y = 36

The general equation for a straight line is y = mx + c, where m stands for the line's slope and c for its y-intercept. The most frequently used straight line equation is one that has to do with geometry.

There are numerous ways to express the equation of a straight line, such as slope-intercept form,  point-slope form, standard form, general form,  etc.

Let's begin by listing out the given information:

We have a quadrilateral ABCD and we want to calculate the area.

We can divide it in three areas (two triangles and one rectangle) and then add the surfaces.

As it is rotated 45 degrees, we can define a "new unit" that is the diagonal of a square of 1 by 1 unit, in the scale of the graph.

This new unit, the diagonal that we will call "d", by the Pythagorean theorem, has a value of:

We will start then with the triangle ABF. It has a side BF that has a value of 2 diagonals (2d) and a side FA that has a value of 3 diagonals (3d). The area of a triangle is half the multiplication of this two sides, so we have:

The second triangle is CED. We repeat the process and we have:

The rectangle BCEF has an area of:

Now we have the three areas. If we add them we get the area of ABCD:

The quadrilateral ABCD has an area of 26 units^2.

And that is our final answer.

The sum of integers should be written like:

9 + (-22) = -13

because the are asking in fact for a SUM of integers

The two integers are 9 and -22

when added you get:

9 + (-22) = 9 - 22 = -13

Therefore, the correct answer is the 1st option.

Given the coordinates of the function;

f(x) = {(7,3), (5,3), (9,8).(11,4)}

The inverse of any coordinate points is gotten by changing the y coordinate valuewith the x coordinate values i.e y = x

f-1(x) = {(3,7), (3,5), (8,9), (4,11)

You can see that the x coordinates has been swapped with the y coordinates.

Similarly;

g-1(x) = {(7, 5),(5,3), (9,7), (11,9)}

The group consists of 4 friends and each friend has 12 tickets.

Each friend uses 4 tickets to ride the roller coaster.

To find the number of tickets each friend has after the ride, subtract the number of tickets used for the ride from the number of tickets each friend had initially.

The area of the shaded figure is 45 [tex]cm^{2}[/tex]

It is given that ABC and BCD are identical triangles and the overlapping area is 19[tex]cm^{2}[/tex]

Now, to evaluate the area of the shaded figure, we will calculate the area of the two triangles ABC and BCD, then we will subtract the overlapping area from it.

So, by evaluating the figure, it comes out that the length of the triangle is 4 units and 1 unit is 2cm.

So, Height of the triangle = 4 * 2 cm = 8 cm

And the base of the triangle is 3 units, then,

Base of the triangle = 3* 2 cm = 6 cm

The area of the triangle = 1/2 * base* height

Area of triangle ABC = [tex]\frac{1}{2} *8*6 = 24cm^{2}[/tex]

The area of both the triangles = area(ABC) +area(BCD)

Since two the triangles are identical, their areas are also identical,

So, the Area of both the triangles = 2*area(ABC)  = 2*24 = 64[tex]cm^{2}[/tex]

Now, The area of the shaded figure = area(ABC) +area(BCD) - overlapping area.

The area of the shaded figure = 64 - 19 = 45 [tex]cm^{2}[/tex]
