Answer: Slope is undefined. x=0

slope calculation: -3-4/0-0 = -7/0 and anything divided by 0 is undefined

the x value in the coordinates is 0 so it’s x=0 line.

vertical lines always have undefined slopes

Answer:

x=0

Step-by-step explanation:

  1. So first of all we need the slope of the line we are trying to find
  2. We get the slope by using the following formula slope=\frac{y_2-y_1}{x_2-x_1}
  3. So when you have two pairs of points, it will be (x_1,y_1) and (x_2,y_2)
  4. so our points are;
  5. (0,4) the first point, so x_1=0,y_1=4 and
  6. (0.-3) the second point, so x_2=0,y_2=-3
  7. Put this in our equation slope=\frac{(-3)-(4)}{(0)-(0)}=\frac{-7}{0}
  8. Oh no, that can't be right, any number divided by zero is <em>undefined</em>, meaning can't be answered. So this line has no slope
  9. <em> </em>So how do we know the equation? Remember,
  10. (a) if the line is horizontal, then the slope is 0,
  11. (b) if the line is vertical then the slope is <em>undefined</em>
  12. So our line is vertical, meaning it is an equation of x
  13. If it were horizontal it would be an equation of y
  14. So vertical, it is x=??
  15. How do we know what x equals? Just look at our points (0,4) and (0,-3)
  16. For both of them x=0 and this is our equation!

For the function F defined by F(x) = x2 – 2x + 4, find F(b+3).
Ivanshal [37]

Answer:

\displaystyle F(b + 3) = b^2 + 4b + 7

Step-by-step explanation:

We are given the function:

\displaystlye F(x) = x^2 - 2x + 4

And we want to find F(<em>b</em> + 3).

We can substitute:

\displaystyle F(b + 3) = (b + 3)^2 - 2(b+3) + 4

Expand:

\displaystyle = (b^2 + 6b + 9) + (-2b -6) + 4

Rearrange:

\displaystyle = (b^2) + (6b-2b) + (9 - 6 + 4)

Combine like terms. Hence:

\displaystyle = b^2 +4b + 7

In conclusion:

\displaystyle F(b + 3) = b^2 + 4b + 7

If 3 = m^x, then we know 9 = (m^x)^2 because 9 is 3 squared.

(m^x)^2 can be simplified to m^{2x}

So now we know 9m^2 = m^{2x}·m^2

Since m^{2x} and m^2 have the same base, we can express it as a single term by adding the exponents together.

So the answer is C) m^{2x+2}

Point c is the center of dilation. line segment b a is dilated to create line segment b prime a prime. the length of c a is 4. t
pychu [463]

The scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.

<h3>What is the dilation of the figure?</h3>

Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.

Point c is the center of dilation. Line segment BA is dilated to create line segment b prime, a prime.  The image of the given problem is attached below. The length of CA is 4.

CA=4

The length of a prime is 16.

AA'=16

The new dimension will be,

CA'=CA+AA'\\CA'=4+16\\CA'=20

Now, the scale factor is the ratio of the new dimension to the original dimension. Thus, the scale factor of the dilation is,

r=\dfrac{20}{4}\\r=5

This will be the same for the line segment BA. Thus, the scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.

0.45 0.40 0.11 This question uses the following probability model for the blood type of a randomly chosen person in the United S
poizon [28]

Answer:

P(O\ or\ A) = 0.85

Step-by-step explanation:

Given

See attachment

Required

P(O\ or\ A)

From the question, we understand that she can only get blood from O or A groups. So, the probability is represented as:

P(O\ or\ A)

This is calculated as:

P(O\ or\ A) = P(O) + P(A)

Using the American row i.e. the blood must come from an American.

We have:

P(O) = 0.45

P(A) = 0.40

So, we have:

P(O\ or\ A) = 0.45 + 0.40

P(O\ or\ A) = 0.85
