Question 3)
Given
The point (1, -5)
The slope m = -5/6
Using the point-slope form of the equation of a line
where
- m is the slope of the line
In our case:
substituting the values m = -5/6 and the point (1, -5) in the point-slope form of the equation of the line
Thus, the point-slope form of the equation of the line is:
Question 4)
Given
The point (-1, 5)
The slope m = -7/2
In our case:
substituting the values m = -7/2 and the point (-1, 5) in the point-slope form of the equation of the line
Thus, the point-slope form of the equation of the line is:

Step-by-step explanation:
The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).
<2 + 40 + 40 = 180 Combine the left
<2 + 80 = 180 Subtract 80 from both sides
<2 = 180 - 80
<2 = 100 degrees.
That's not the answer. We have to solve for x
<2 = x + 106
100 = x + 106 Subtract 106 from both sides
100 - 106 = x
x = - 6
Answer:
19404
Step-by-step explanation:
sum of arithmetic series is
Sn = n/2 (2a + (n-1)d)
or
Sn = n/2 (a + an)
a = 1st unit
an = last unit
d = difference
8-3 or 13-8 so d = 5
then first step is to find the value of n
an = a + (n-1)d
438 = 3 + (n-1)5
438 - 3 = 5n - 5
435 = 5n - 5
435 + 5 = 5n
440 = 5n
n = 440/5
n = 88
then we can find the sum
Sn = 88/2 (3 + 438)
S88 = 19404
