Answer: 72
Step-by-step explanation:
Let x represents the units digit of the number, then the value of tens digit will be .
According to the question , we have the following equation:-
Subtract 5 on both sides , we get
Now, Divide 2 on the both sides , we get
Now, the unit digit of the number = 2
The tens digit of the number = 2+5=7
Then , the number will be : 72
Angles at right-angle add up to 90 degrees
The measure of acute angle Tryon Street forms with Barton Road is <em>33 degrees</em>
The angle is given as:
---- <em>Angle formed by Tryon Street with Olive Tree Lane. </em>
The measure of the acute angle formed by Tryon Street with Barton Road (B) is calculated using:
---- angle at right-angle
Make B the subject
Substitute 57 for A
Hence, the measure of acute angle is 33 degrees

Answer:
Option B
Step-by-step explanation:
we have
we know that
<u>The vertical line test </u>is a visual way to determine if a curve is a function or not. A function can only have one value of y for each unique value of x
In this problem
The given function passes the vertical line test
therefore
f(x) is a function
<u>The Horizontal Line Test</u> is a test use to determine if a function is one-to-one
If a horizontal line intersects a function's graph more than once, then the function is not one-to-one.
In this problem
The given function fails the horizontal line test
because for f(x)=0 x=-3, x=-1, x=3
therefore
It is no a one-to-one function
