Step-by-step explanation:
Equation of a line with an slope of 1/2 that contains (-4, 7) is 
<em><u>Solution:</u></em>
We have been given a point and slope of an equation and have been asked to write it in an equation. The two forms of writing a point and slope in equation are point slope form and standard form.
The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. The standard form of a line is just another way of writing the equation of a line.
To write in standard form we will first write it in point slope form and then rearrange it into a standard from.
<em><u>The formula for point slope form:</u></em>

where "m" is the slope of line
Given that "m" =
and 

Now, let us convert this equation to standard form
0.5x + 9 = y
0.5x - y = -9
Thus we have found out equation of line in point slope and standard form
Let's write the function that represents the problem:
ax = 210x + 240
We are going to evaluate the first five nights:
a0 = 210 * (0) + 240 = 240
a1 = 210 * (1) + 240 = 450
a2 = 210 * (2) + 240 = 660
a3 = 210 * (3) + 240 = 870
a4 = 210 * (3) + 240 = 1080
We then have the following terms:
240, 450, 660, 870, 1080
We observe that the common difference of the terms is:
210
Therefore, since they have the same common difference, we are facing an arithmetic sequence.
Answer:
A the situation represents an arithmetic sequence because of the successive and values have a common difference of 210
Answer:
In a parallelogram, consecutive angles are supplementary. Thus,
B + C = 180^{\circ}
(2x+15)+x=180
3x+15=180
3x=165
x=55
