A) a1=0 a2=9
b)m1=0 m2=5
c)r1=0 r2=1.25 or 5/4
Answer:
a) The basic rate of pay is 6 sterling pounds per hour.
b) The higher rate of pay is 10 sterling pounds per hour.
Step-by-step explanation:
Both segments of the curve are first order polynomials, which means that each have constant slopes.
a) The basic rate of pay is the value of the slope (
), in sterling pounds per hour, of the line for the first 20 hours worked, that is:
(1)
Where:
- Change in hours worked, in hours.
- Change in pay, in sterling pounds.
If we know that 
and 
, then the basic rate is:
The basic rate of pay is 6 sterling pounds per hour.
b) By using (1), we calculate the higher rate of pay below. If we know that 
and 
, then the higher rate is:
The higher rate of pay is 10 sterling pounds per hour.
We have
we have x is less than or equal 50/7
They are the same slope
they are negative inversees (they multily to get -1)
2
-1/2
use the square viewer (on TI)
The relationship between the slopes of two lines that are parallel is they are the same.
The relationship between the slopes of two lines that are perpendicular is they are negative inverses of each other (they multiply to -1).
A line that is parallel to a line whose slope is 2 has slope 2.
A line that is perpendicular to a line whose slope is 2 has slope -1/2.
What must be done to make the graphs of two perpendicular lines appear
to intersect at right angles when they are graphed using a graphing
utility?
Answer:
If you are trying to solve the inequality for "x" Then your answer is, <u><em>"x>9/5" </em></u>That is the inequality form. If you are looking for the interval notation form then your answer is <u><em>"9/5, infinity" </em></u>
