Answer:

C. (-2, -1)

Step-by-step explanation:

It can help to plot the points.

For rotation 180 degrees, the center of rotation is the midpoint of the segment joining the given point and its image. That means you want to find the other end of a segment with one end (-4, 1) and midpoint (-3, 0).

For center of rotation O, this means ...

O = (A +A')/2

2O -A = A'

A' = 2(-3, 0) -(-4, 1) = (-6+4, 0 -1) = (-2, -1)

The coordinates of the image are (-2, -1).

Evaluate the function at the indicated values. (If an answer is undefined, enter UNDEFINED.) f(x) = 8x + 9 f(1) = f(−2) = f 1 2

creativ13 [48]

Answer:

f(1)=17

f(-2)=-7

$f(\frac{1}{2})=13$

Step-by-step explanation:

We are given that a function $f(x)=8x+9$

We have to evaluate f(1),f(-2) and $f(\frac{1}{2})$

Substitute x=1 in the given function then we get

$f(1)=8(1)+9=17$

f(1)=17

Substitute x=-2 in the given function then we get

$f(-2)=8(-2)+9=-16+9=-7$

f(-2)=-7

Substitute $x=\frac{1}{2}$

Then we get

$f(\frac{1}{2})=8(\frac{1}{2})+9=4+9=13$

$f(\frac{1}{2})=13$

Vertical line that passes through the point (3,-8)

Marina86 [1]

Hi there! The answer is x = 3.

All vertical lines have an undetermined slope (since the formula which represents the slope has a denominator of 0). Therefore the general formula of a vertical line is the following x = c, with c representing the x-coordinate of the point that is passed by the line. Therefore, in your situation we get the line x = 3. When we plot this line, we can see it is a vertical line with x-coordinate 3 and that all values of y are passed, also y = - 8.

anygoal [31]

Answer:

George = 1.39 m

Step-by-step explanation:

Katie = 1.47 m

George = 1.47 m - 0.08 m (8 cm = 0.08 m)

George = 1.39 m
