A triangle has a bottom left angle of (x + 15) degrees and a bottom right angle of (x degrees). 1 parallel and horizontal line s
its at the top point of the triangle. Another parallel and horizontal line sits at the base of the triangle. The exterior angle to the bottom right angle of the triangle is (4 x minus 20) degrees.
What is the value of x?
What is the value of x?
1 answer:
Answer:
<em>The value of x is 40°</em>
Step-by-step explanation:
The triangle described in the text of the question is shown in the image attached.
Note the angles x and 4x-20 are supplementary since they form a line. Thus:
x + 4x - 20 = 180
Simplifying:
5x - 20 = 180
Adding 20:
5x = 200
Solving:
x = 200/5 = 40
The value of x is 40°

Answer:
Inverse variation k=4
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or
In this problem
The graph represent a inverse variation
Because
if x increases ----> y decreases
if x decreases ----> y increases
Find the value of k
we have that
For x=2, y=2 -----> see the graph
substitute
ANSWER
See explanation.
EXPLANATION
The given expression is
The parent function is
We can see that the transformation is of the form:
This is a vertical upward shift of the parent function by k units.
The graph of y=x^2+5 can be obtained from the graph y=x^2 by shifting the graph of y=x^2 up by 5 units.
b) The graph of y= 10x^2 can be obtained from the graph y=x^2 by stretching vertically the graph of y=x^2 by a factor of 10.
