True or false? The graph represents a function

Mathematics
2 answers:
Cloud [144]3 years ago

Answer:

False. This is not a function.

Step-by-step explanation:

By using the vertical line test, it shows that this graph is not a function. The imaginary vertical line would go through the graph twice. To be a function, the imaginary vertical line can only go through once.

The statement is false because if the red line had a vertical line going through it the line would hit it twice as shown in the picture below

What is the equation of the perpendicular bisector of the segment joining points A(1, 1) and B(5, 7)?
Elden [556K]
Bisector must pass through the mid-point, so we have to find out that mid-point of the segment:

mid point = x₁+x₂ / 2 , y₁+y₂/2
= 1 + 5 / 2 , 1 + 7 / 2
= 6/2 , 8/2
= (3, 4)

Slope of given segment = m = y₂-y₁ / x₂- x₁
m = 7-1 / 5-1
m = 6/4
m = 3/2

Now, segment which is perpendicular, will have the opposite & reciprocal slope, So, it would be: -2/3

We know, y - y₁ = m(x - x₁)
y - 4 = -2/3(x - 3)
y - 4 = -2/3x + 2
y = -2/3x + 6

In short, Your Final Answer would be: y = -2/3x + 6

Hope this helps!

Find the length of the line segment displayed below. Round your answer to the nearest hundredth (2 decimal places)
svlad2 [7]

Answer:

AB=5.83

Step-by-step explanation:

Distance Formula=

\sqrt{(x2 - x1)^{2}  - (y2 - y1)^{2} }

Plugging our values in, we get:

\sqrt{(7 - 2)^{2} + (4 - 1)^{2}  }

And if we solve it like this:

\sqrt{25 + 9}

We end up with:

\sqrt{34}

Which is about 5.83

What is 25/100 in simplest form
barxatty [35]
It would be 1/4. because 25 divided by 5 is 5. 100 divided by 5 is 20.
5 can be divide again so it would be 1 and 20 can be divided by 5 so it would be 4. Put them together and it would be 1/4.
