Find the percentage decreases from 500 to 300

Step-by-step explanation:

Address the formula, input parameters & values

Formula :

Difference/Initial Value

Initial Value X = 500 & New Value Y = 300

Decrease = (X - Y)

(500 - 300) / 500 x 100 = ?

step 2

Apply the values in the percentage decrease {(X - Y)/X x 100} formula

=(500 - 300) / 500 x 100

=200/500 x 100

= 40%

(500 - 300) / 500 x 100 = 40%

The percentage reduction can be written as 60% of 500.

40 percent decrease (%↓) or reduction from 500 is 300.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
