Answer:

well if she has 52 notions and 16 patterns you will have to multiply

ABC Office Supply offers an electric typewriter for $129.95. If ABC received a 15% markup on cost by selling the typewriter at t

const2013 [10]

A 15% percent markup means that the typewriter cost was increased by 15%, or 0.15 by moving the decimal 2 places to the left. If the original price was x, and 15% of it is 0.15*x, we can add them up to get 1.15*x=129.95. Dividing both sides by 1.15, we get x=113 dollars

Please help me with this math homework thanks :)

Place a point at (0,-5) because that is the y-intercept (the -5 on the vertical line)

Since the slope is negative two which can be re-written as -2/1 (rise/run) you go down two and to the right once or up two and to the left once, it doesn't matter which. Another point can be placed at (1,-7) or (-3,-1), it still doesn't matter which.

Then you can draw a line connecting the two points.

I hope this helps :)

Someone help with this midpoint question please

Natali5045456 [20]

Answer: D) (2,0)

Step-by-step explanation:

These are your values.

$(-2,4);(6,-4)$

Remember this means;

$(x_1,y_1);(x_2,y_2)$

The formula for finding the midpoint of a segment is simple. Add both x's and y's and divide them by 2 separately. Or, if you like to follow formulas, here you go.

Let M be midpoint.

$M=\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}$

$M=\frac{-2+6}{2},\frac{4+(-4)}{2}$

$M=\frac{4}{2} ,\frac{4-4}{2}$

$M=\frac{4}{2} ,\frac{0}{2}$

$M=2,0$

Are exponential function one to one. How can you tell? What does this tell you about their inverses

aleksandrvk [35]

See in the explanation

<h2>Explanation:</h2>

<h3>1. Are exponential function one to one. How can you tell?</h3>

A function $f$ is one-to-one if each value of $x$ corresponds to exactly one value of $y$ .

To demonstrate this, we take the Horizontal Line Test that states:

<em>A function $f$ has an inverse function if and only if there is no any horizontal line that intersects the graph of $f$ at more than one point.</em>

As you can see in the first figure, the horizontal line $y=3$ (the green one) intersects the graph of the exponential function $y=e^x$ (the red one) in just one point. If you take every horizontal line $y=y_{0}$ with $y_{0}$ any real number, you will find that every line intersects the exponential function in just one point. Therefore, this function is one-to-one

<h3>2. What does this tell you about their inverses?</h3>

Another important thing is that:

A function has an inverse function if and only if is one-to-one.

As we have demonstrated that exponential functions are one-to-one by Horizontal Line Test, then we conclude exponential functions have inverse functions. The domain of the inverse function is the range of the original one and the range of the inverse function is the domain of the original one. The inverse of $y=e^x$ is $y=ln(x)$ whose graph is the second figure below.
