The linear equation that represents the scenario is: y = 235x + 15.

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given points into the formula, we have;

Slope = (1660 - 955)/7 - 4)

Slope = 705/3

Slope = 235.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁) or y = mx + c

Where:

By critically observing the graph (see attachment) which models the data in the given table, we can reasonably infer and logically deduce that the linear function is given by: y = 235x + 15.

Answer:

g(2) = 0

Step-by-step explanation:

g(2) is the value of x.

So, we would place g(2) with x:

g(2) = 2(2) - 4

g(2) = 4 - 4

g(2) = 0

If the given function is g(x)=2x-4, the value of g(2) will be 0.

The function is described as a particular kind of relationship, and each value in the domain is associated with exactly one value in the range according to the function. They have a predefined domain and range.

It is given that the function is, g(x)=2x-4

We have to find g(2).

In order to find the g(2), substitute 2 as the place of x as,

g(x)=2x-4

g(2)=2×2-4

g(2)=4-4

g(2)=0

Thus, for the given function g(x)=2x-4, the value of g(2) will be 0.

Answer: line mn = 4

Step-by-step explanation:

Note: There's a chance i might be wrong.

Due to de=12, and ef=10, it seems as though a pattern is clear and that ef was -2 the size of de. Since lm is 6,  de got divided by 2, 12/2=6

Therefore, subtract 2 from 6, and you get 4.

The set of possible dimensions (length and width) of the field are {13.5, 10, 5.5, and 26}.

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle = 2(L+W)

Where W is the width of the rectangle  and L is the length of the rectangle

The perimeter = 2W+ L

37 = 2W + L

L = 37 - 2W

Hence,

area = W(37 - 2W)

143 = 37W - 2W²

-2W² + 37W - 143 = 0

W² - 18.5 W + 71.5 = 0

W = 13.5, 5.5

Take the value of W = 13.5

Then,

L = 37  - 2W

L = 37 - 2(13.5)

L = 10 meters

Take the value of W = 5.5

Then,

L = 37  - 2W

L = 37 - 2(5.5)

L = 26 meters

Therefore, the set of possible dimensions (length and width) of the field are {13.5, 10, 5.5, and 26}.

1) The relationship between ∠1 and ∠3 is that they are corresponding angles.

2) The relationship between ∠8 and ∠4 is that they are alternate exterior angles

3) The relationship between ∠2 and ∠3 is that they are supplementary angles.

When it comes to congruent angles, we know that when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.

Now, in the first figure, we see that there are a total of eight angles and we also see that 2 parallel lines have been intersected by a third one. Thus, some of the angles will be congruent to others. In this case, we see that the relationship between ∠1 and ∠3 is that they are corresponding angles.

Now, in the second figure, we see that there are a total of eight angles and we also see that 2 parallel lines have been intersected by a third one. Thus, some of the angles will be congruent to others. In this case, we see that the relationship between ∠8 and ∠4 is that they are alternate exterior angles because they are formed on the outside of the parallel lines.

The rate at which the water level dropped each hour is 5 / 34 inches per hour.

In order to determine the rate  at which the water level dropped each hour , divide the total decrease in the water level by the total time it took for the water to decrease.

Division is the process of  grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.

Change in water level per hour = total decrease / change in time

Change in time = 11 - 8 : 10 = 2 : 50 am = 2 hours 5/6 minutes

Change in water level per hour = 5/12 ÷ 2 5/6
