A graph of the linear equation (3x + 2y = 6) in standard form is shown in the image attached below.

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

In Mathematics, the graph of any proportional relationship such as a linear equation is characterized by a straight line as shown in the image attached below.

Next, we would rewrite the linear equation in standard form as follows:

3x + 2y = 6

2y = 3x + 6

Dividing all through by 2, we have:

2y/2 = 3x/2 + 6/2

y = 3x/2 + 3

In conclusion, a graph which represents the linear equation (y = 3x/2 + 3) shows a proportional relationship between the value of x and y.

Answer:

The correct option is (b) truth value. If we are given two statements, the first statement is called the hypothesis and the second is its conclusion.

Maggie's mistake on the solution of the expression for x was when she subtracted 7x to both sides, the result should have been -3x and not 3x.

The equation is given as follows, as the angles are congruent, that is, they have the same measure:

4x + 2 = 7x - 25.

First, we isolate x on the left side of the equality, subtracting 7x from both sides, hence:

4x + 2 - 7x = 7x - 25 - 7x

Then the correct expression is:

-3x + 2 = -25

Which is where Maggie's mistake happened, on the subtraction of 4x and 7x.

Then, isolating x, we subtract 2 from both sides of the equality, to remove the +2 term on the left side of the equality.

-3x = -27

3x = 27

x = 27/3

x = 9.

The correct solution is x = 9.

We need to know about fraction to solve this problem. The amount Reshma spent on comic books is Rs 165 and the amount that is left with her is Rs 495.

We can solve this problem by calculating what 1/4th of 660 will be. In this question we know that Reshma spends 1/4th of her pocket money on comic books out of Rs 660. We can think of 660 being divided in 4 parts equally and that Reshma spends one part of it. The amount that will be left with Reshma is the rest three parts.

Reshma spends= 1/4x660=165

Amount left= 660-165=495

Therefore the amount Reshma spends on comic books is Rs 165 and the amount that is left with her is Rs 495.

Time taken by Roni to mow the field = 30 minutes

Time taken by Allie to mow the field = 75 minutes

Work done by the Roni = x/30

Using relations in a right triangle and the Pythagorean Theorem, it is found that the missing side lengths are as follows:

There are three relations in a right triangle, given as follows:

For this problem, we have that:

tan(A) = b/a.

Hence:

5/12 = 6/a

Applying cross multiplication, the side a is found as follows:

5a = 72

a = 72/5

a = 14.4.

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following equation:

Answer:

total earnings at 6th hour: 111

hourly wage (slope): 18.5

Step-by-step explanation:

A linear function has a linear relationship, which essentially states as x increases by one, the y-value increases by some constant amount yielding a straight line.

The slope, or how much the y-value changes as x changes by 1 is generally written as: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We can choose any two points and this should yield the slope of the function, but it's a lot easier to choose y-values that are only separated by an x-value of one.

Let's say: [tex](x_1, y_1)=(4,\ 74)\text{ and }(x_2,y_2)=(5,\ 92.50)[/tex]

If we plug the values into the slope formula we just get: [tex]\frac{92.50-74}{5-4}=\frac{92.50-74}{1}=92.50-74[/tex]

And this makes sense, since by definition of a slope, it's just the change in y over change in x. This is equivalent to how much the y-value changes as x increases by one, so if we select two values with a difference of one in their x-values, the slope just turns out to be the difference between the two numbers.

Simplifying our expression we get: [tex]92.50-74=18.5[/tex]

This slope in this context represents how earnings increases as the hour increases, or in other words the hourly wage.

To calculate the earnings of the 6th hour we can just use the definition of a slope. From the x-value 5 to the x-value 6, the y-value should simply increase 18.5

So adding 18.5 to the y-value at x=5 we get: [tex]92.5+18.5=111[/tex]

The blue portion of the wall in Marcus's bedroom is discovered to be 144(1/15) or 9.6 square feet in size.

Use the standard formula of Length x Width = Area to calculate the area of a wall.

Because square feet is the most commonly used measurement in the world when it comes to wall sizes, the measurement unit will have an impact on how you calculate square footage.

It is given that a wall in Marcus's bedroom is 8 feet high and 18 feet long.

So, the area of a wall = 8 × 18

                                   = 144

Further, 1/15 portion is painted with blue color.

So, the portion that is painted with blue = 144 × 1/15

                                                                   = 9.6

The sinusoidal function that matches the graph given is:

g(x) = 4cos((π/7)x) - 2.

The cosine function is defined as follows:

g(x) = acos(bx)+d.

The coefficients have these following roles:

For this problem, we use a cosine function because the function is not zero at the origin, while for the sine it is.

From the graph of this function, the maximum value is of 2, while the minimum value is of -6, hence the amplitude is found as follows:

2a = 8 (difference between these values).

a = 4.

Then:

g(x) = 4cos(bx) + d.

A function with amplitude of 4 should oscillate between -4 and 4, while this one oscillates between -6 and 2, meaning that it was shifted 2 units down, hence d = -2 and:

g(x) = 4cos(bx) - 2.

The period is of 14 units, hence:

2π/b = 14

14b = 2π

b = π/7

Hence the function is:

g(x) = 4cos((π/7)x) - 2.
