Ok I'm doing home work and need to show why 1/2 of 60 is not the same as 1/2 of 24 please help! It will give you 24 points.
Tems11 [23]
Simple,

1/2 of 60

re-write it as 0.5 of 60 aka 0.5*60

which is 0.5*60=30

Do the same with 1/2 of 24.

0.5 of 24

0.5*24=12.

Thus, it's not the same because they are different numbers and different number give you different answers.

PLEASE SOLVE 20 POINTS
Soloha48 [4]

Answer:

1. Not possible. The slope of such a line is undefined. Its equation is x=7.

2. y = 3x -2

3. The slope is undefined. (The line is a vertical line.)

Step-by-step explanation:

1. The y-axis is a vertical line. Computing the slope of such a line involves division by zero, an operation that is undefined. Since the line is parallel to the y-axis, there is no y-intercept.

In slope-intercept form, the equation would be useless:

... y = (undefined)x + (no such value)

If your point is supposed to be (7, 8)*, the more useful equation is the "standard form" equation:

... x = 7

2. The slope of the perpendicular line is the negative reciprocal of this:

... m = -1/(-1/3) = 3

In point-slope form, the equation of the perpendicular line through the given point is ...

... y = 3(x -2) +4

... y = 3x -2 . . . . . . . . simplified to slope-intercept form

3. The slope is computed from ...

... m = (change in y)/(change in x) = (-3 -4)/(-1 -(-1)) = -7/0 = undefined

The slope is undefined. This tells you the line is a vertical line. Its location is the x-value of the points, ...

... x = -1

_____

* If your point is really (77, 88), then the line has equation x = 77.

In the figure M ab =45 and M cd= 23 what is the value of x?
const2013 [10]

Answer:

34°

Step-by-step explanation:

The measure of vertical angles formed by two chords is equal to one half the sum the measures of the arcs.

In other words, x is the average:

x = (23° + 45°) / 2

x = 34°

If ƒ(x) = 2x, then ƒ -1(x) =<br><br> -2x<br> ½x<br> x - 2
kap26 [50]

Answer: second option

Step-by-step explanation:

To find the inverse function of the given function f(x):

f(x)=2x

You need to:

Substitute f(x)=y into the function:

 y=2x

Now, you need  to solve for "x", to do this, you must divide both sides of the function by 2:

\frac{y}{2}=\frac{2x}{2}\\\\\frac{y}{2}=x

Now, replace "x" with "y" and replace "y" with "x":

\frac{x}{2}=y

Therefore, substituting y=f^{-1}(x) you get:

f^{-1}(x)=\frac{x}{2} or  f^{-1}(x)=\frac{1}{2}x
