Answer:
The first option is not a function
Explanation:
A function is where there is no repeated x values
Just a reminder
Answer:
6
Step-by-step explanation:
Straight line is 180
square = right angle=90
180-90=90
5x+(x+54)=90
6x+54=90
6x=36
x=6
Hope this helps :D
Answer:
1.49
Step-by-step explanation:

in this problem you also need to use scientific notation period to do scientific notation you need to go to the first non-zero digit after the decimal . and in this case that is one next thing you do is put the next numbers after the decimal that you just put in front of the one which is 49 in this case and that gives you your answer of 1.49
<u>Answer:</u>
The point-slope form of the line that passes through (5,5) and is perpendicular to a line with a slope of
is 4x + y -25 = 0
<u>Solution:</u>
The point slope form of the line that passes through the points
and perpendicular to the line with a slope of “m” is given as
---- eqn 1
Where “m” is the slope of the line.
are the points that passes through the line.
From question, given that slope “m” = 
Given that the line passes through the points (5,5).Hence we get

By substituting the values in eqn 1 , we get the point slope form of the line which is perpendicular to the line having slope
can be found out.
y - 5 = -4(x - 5)
y - 5 = -4x + 20
on simplifying the above equation, we get
y - 5 + 4x -20 = 0
4x + y - 25 = 0
hence the point slope form of given line is 4x + y - 25 = 0
1. True
