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
Answer:
x = 4.5
Step-by-step explanation:
thesetwo triangles are similar to we can create a proportion from corresponding sides as follows:
4/9 = 2/x
cross-multiply:
4x = 18
x = 4.5
Your answer would be 32. You add 23 + 9 and you get 32.
Step-by-step explanation:
3x/2 - 2 > 7
3x/2 > 9
3x > 18
x > 6
for the line graphic below it seems you need to calculate x.
please consider that both angles together must be 180°, as they represent the full rotation area around one point on one side of a line.
8x + (4x + 60) = 180
8x + 4x + 60 = 180
12x = 120
x = 10
3x67=201 and that is the answer for this question
