Y=2x+0.5

4.5=2x+0.5
4.5-0.5=4

4=2x
4÷2=2

x=2

(50 POINTS) The figure is transformed as shown in the diagram. Describe the transformation. A) dilation, then reflection B) refl

Helga [31]

Answer:

Hi there I was just working on this question on UsaTestPrep and idk if the answer is really correct but here: C: reflection then rotation.

Step-by-step explanation:

Extra Info:

Dilation is when the shape changes in size, which doesn't happen.

Translation is when it just moves across. It may look like that is happening here, but I'll explain.

The triangle is first reflected along the line . Imaging putting a mirror on the x=0 line (the y axis, basically), and you'd see 1 to 2.

Then, it is rotated around the point . Get a bit of tracing paper, draw over 2, and then, holding the tracing paper down at (works well with a pencil), rotate it round and you will find it fits perfectly over 3.

Also is this the diagram?

The given function is f(z)=3z-8 for the values f(-4), f(2) and f(z-7) respectively -20, -2 and 3z-29 respectively.

The given function is f(z)=3z-8.

We need to find the value of f(-4), f(2), f(z-7).

<h3>What is a function?</h3>

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

Now to find f(-4), replace z from -4.

f(-4)=3(-4)-8=-12-8=-20

Now to find f(2), replace z from 2.

f(2)=3(2)-8=6-8=-2

Now to find f(z-7), replace z from z-7.

f(z-7)=3(z-7)-8=3z-21-8=3z-29.

Therefore, the given function is f(z)=3z-8 for the values f(-4), f(2) and f(z-7) respectively -20, -2 and 3z-29 respectively.

You must accumulate 790 points to achieve your goal this month. If you work 22 business days this month, how many points must yo

Digiron [165]

Answer:

36 points each day.

Step-by-step explanation:

We have been given that we must accumulate 790 points to achieve our goal this month.

To find the number of points earned each day, on average, we will divide total number of points achieved in a month by number of business days we worked.

$\text{ Points earned each day on average}=\frac{790}{22}$

$\text{ Points earned each day on average}=35.9090909\approx 35.91$

If we need an integer answer, we can round 35.91 to 36. Therefore, we must earn 36 points each day, on average to meet our goal.
