Answer:
k(-1) = 7.
Step-by-step explanation:
k(-1) is the value of the function k when x = -1.
You read this off the graph.
Find the value of the point on the graph which corresponds to x = -1. From x = -1 on the horizontal axis move straight up until you meet the graph of k. Now look horizontally to the right and read off the value on the vertical
y-axis
You'll find it is 7.
Answer:
The measure of one angle is 
, and the measure of the other one is 
Step-by-step explanation:
Recall that supplementary angles are those whose addition renders 
We need to find the measure of two such angles whose difference is precisely 
.
Let's call such angles x and y, and consider that angle x is larger than angle y, so we can setup the following system of equations:
We can now solve this by simply combining term by term both equations, thus cancelling the term in "y", and solving first for "x":
So, now we have the answer for one of the angles (x), and can use either equation from the system to find the measure of angle "y":
Answer:
the answer is x=99/20
Step-by-step explanation:
multiply both sides
Answer:
Step-by-step explanation:
If the slope is 1/5, we can interpret this as rise/run = 1/5. We could (if we wished to do so) find the hypotenuse by using the Pythagorean Theorem:
hypo = +sqrt( 1^2 + 5^2)
In this case we dilate the triangle defined by the slope 1/5:
2/10, 1/10/(1/2), 10/50, etc., all represent right triangles whose hypotenuses lie on the same line (the line with slope 1/5).

the original price is $212.50
