Your friend claims that if a line has a slope less than 1, then any line perpendicular to it must have a positive slope. Is your
1 answer:
Answer:
The friend's claim is not correct
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal yo -1)
Example
A given line has a slope of ---> (is less than 1)
the slope of the line perpendicular to the given line is equal to
substitute
so
the perpendicular line don't have a positive slope
therefore
The friend's claim is not correct

Answer:
Step-by-step explanation:
We have been given a parallelogram. We are asked to solve for the values of x and y.
We know that opposite sides of parallelogram are equal, so we can set equation as:
Similarly, we will solve for y.
To solve for z, we will subtract y from x as:
Therefore, the value of z is negative 3.
Answer:
c=rt is the equation to express the total cost c to use the internet at the coffeehouse for t hours.
Step-by-step explanation:
Given A coffeehouse charges a flat rate, r for each hour customer wants to use the internet. we have to write the equation to express the total cost c to use the internet at the coffeehouse for t hours.
Charges of internet per hour = r
Total hour = t hours
Hence, Cost = (Charges per hour)(Total hours)
=
∴ c=rt
which is the linear equation to express the total cost c to use the internet at the coffeehouse for t hours.
