Answer:

Step-by-step explanation:

We are given that 80 is increased by 25% and then decreased by 25% so we are to find the final value.

Increase of 25% in 80 = 25% of 80

= 25/100 × 80

= 20

So our new value after 25% increase = 80 + 20 = 100

Now this new value is decreased by 25% = (100 - 25)% of 100

= 75/100 × 100

= 75

Answer:

See below.

Step-by-step explanation:

Increases by 25% :- it is 80 * 1.25 = 100.

100 decreased by 25% = 100 * 0.75

= 75.

Describe the slope of the line Find the slope

Dmitry_Shevchenko [17]

Answer:

Question one: Zero slope
Question two: $m=\frac{0}{4}$

Step-by-step explanation:

Given the following questions:

Question one:

The following line is what you call a "zero slope." Zero slopes are lines that are neither decreasing or increasing and remain at a constant or just a straight line.

Question two:

Point A = (-2, -3) = (x1, y1)
Point B = (2, -3) = (x2, y2)

Using the formula for slope or rise over run we will solve and find the slope of this line.

$m=\frac{y2-y1}{x2-x1}$
$m=\frac{-3--3}{2--2} =\frac{0}{4}$
$m=\frac{0}{4}$

The slope of this line is "0/4."

Hope this helps.

What is the location of the point on the number line that is 3/5 of the way from a=2 to b=17

makkiz [27]

Answer:

Step-by-step explanation:

The distance that a is to b is b-a=17-2=15.

The line segment from a=2 to b=17 has length 15.

We need to know what is 3/5 of 15.

3/5 of 15 means what is 3/5 times 15?

(3/5)(15)=3(3)=9

So this means we are looking to make a line segment that is 9 units from 2 which is 2 to 11.

So 11 is 3/5 the way from a=2 to b=17.

Let's check from 2 to 11 that is a length of 9 and from 2 to 17 that is a length of 15.

Is 9/15 equal to 3/5?

Yes, 9/15 can be reduced to 3/5.
