Answer:

Mid-point: (0,-5)

Equation: y=\frac{7}{3}x-5

Step-by-step explanation:

To find the mid-point of AB, simply add up their x and y coordinates and divide by 2 respectively to find their middle point.

(\frac{{x__A}+{x__B}}{2},\frac{{y__A}+{y__B}}{2})

(\frac{{-7}+{7}}{2},\frac{{-2}+{(-8)}}{2})

(0,-5)

To find the perpendicular slope that passes through the mid-point, we need to know the slope between AB first.

Slope of AB: \frac{{y__2}-{y__1}}{{x__2}-{x__1}} = \frac{{-8}-{-2)}}{{7}-{(-7)}} = \frac{-6}{14} = \frac{-3}{7}

Multiplying slopes that are perpendicular with each other always results in -1.

\frac{-3}{7}*m = -1

m=\frac{7}{3}

By the point slope form:

({y}-{y__1})=m({x}-{x__1})

Plug in the coordinates of the mid-point:

({y}-{(-5)})=\frac{7}{3} ({x}-{0})

Equation: y=\frac{7}{3}x-5

Ernesto is shopping at store that is having a clearance sale. The price of everything in the store is discounted by 25%. If Earn

$17.49 because you multiply 22 by .25 getting 5.5. You subtract that from the original 22 getting 16.5 which you then multiply by the sales tax .06. Add the tax amount to the 16.5 to get 17.49.

Identify the percent of change as an increase or a decrease. 4/5 to 3/5
vovikov84 [41]

Answer:

Decrease

Step-by-step explanation:

So, I encourage you to grab a calculator and see for yourself

Put in the function: 4/5 into a standard calculator. You will see that it will come out to .8

Put in the function: 3/5 into a standard calculator. You will see that it will come out to .6

.6 is less than .8, just as 3/5 is less than 4/5.

Another analogy that can be used is seeing the fraction as a real-life object.

Let's say that you make two pies. You cut the pie evenly into five slices. You set them on the table and leave them for whoever wants to eat them. You see that Pie 1 has two slices missing (3/5) and that Pie 2 has one slice missing. (4/5)

3 out of 5 slices are left of Pie 1.

4 out of 5 slices are left of Pie 2.

Pie 1 has less than Pie 2 does.

Hope this has helped!
