Answer:

8%

Step-by-step explanation:

Tax equals the original amount times the tax rate

We can find the tax by taking the amount he paid minus the original amount

tax = 156.6 - 145

tax = 11.6

tax = original amount * tax rate

11.6 = 145 * tax rate

Divide each side by 145

11.6/145 = 145/145 * tax rate

.08 = tax rate

To change this to percent, multiply by 100%

.08*100% = 8%

Point F' corresponds to point D. point E'. point F. point E.
Zepler [3.9K]

Answer:

  F' corresponds to point F

Step-by-step explanation:

When a point is the result of some transformation, we often designate that result using the base name of the original, with a prime (') added. In this case, we expect that F' is the transformation of point F.

__

<em>Comment on point naming</em>

Of course, points can be given any name you like. These conventions are adopted to aid in communication about transformations and correspondence between points. It would be unusual--even confusing, but not unreasonable, for point F' to correspond to point D, for example. In the case of certain transformations, point F' may actually <em>be</em> point D.

What is the equation of the line in slope-intercept form?
belka [17]

Answer:

y = 3/5 x+3

Step-by-step explanation:

two points on the graph

(-5,0) (0,3)

the y intercept is 3  (this is where it crosses the y axis)

the slope is

change in y     0 to 3            up 3

------------------  = -------------- =  -------        =   3/5

change in x      -5 to 0             right 5


we can tell the slope is positive because it goes from bottom left to top right

a negative slope goes from top left to bottom right

slope intercept form is

y=mx+b

y = 3/5 x+3
