Answer:
option A
Step-by-step explanation:
given coordinate (3, -6) and (–7, –4)
to find the equation of line
slope of the line passing through both the point will be
equation of line
( y - y₁ ) = m ( x - x₁ )
x + 5 y = -27
line which will not intersect will be parallel to it so option A has same slope as our line equation i.e. -1/5
hence, correct answer is option A
3(b+6) = 3*b + 3*6 = 3b + 18
An explanation for this is that a straight line has a angle degree value of 180. Therefore if you draw the line that creates a 139 degree angle, the rest of the line would have an angle measurement of what is left of the 180 degrees. So to get x you would start with the 180 degree straight line value and subtract the 139 degrees of the line that divides it. so equation is:
180 - 139 = x
And and you get 41 degrees.
(To word this another way the two angles of x and 139 have to add up to the straight line of 180 degrees. Therefore another equation could be:
139 + x = 180
which is basically the same equation but might be easier explanation for some to understand.)
questions 7 and 8 are the same but instead of straight line with 180 degrees, you start with right angle with 90 degrees. Therefore x and the 18 degree angle have to add up to 90 degrees making an equation of:
x + 18 = 90
Or
x = 90 - 18
answer would be
x = 7w
The little square in the top left corner means it is a right angle which equals 90 degrees.
The bottom angle is given as 56.7 degrees.
The three inside angles of a triangle need to equal 180 degrees.
The missing angle = 180 - 90 - 56.7 = 33.3 degrees
