subtract 8 from both sides:

-6x+8-8=20-4x-8

simplifiy:

-6x=-4x+12

Add 4x to both sides:

-6x+4x=-4x+12+4x

Can someone help me plzz??

Answers

Answer:

(0,20)

Step-by-step explanation:

1) we can represent the situation as coordinates

lets have # of texts be "x" variable

lets have bill be "y" as the y variable is always the dependant variable and the cost of the phone bill is dependant upon the number of texts so

y=mx+b-slope-intercept form

coordinates: (50,25) and (100,30)

slope: (30-25)/(100-50)

5/50=1/10

hence slope=1/10

y=1/10x+b

substitute in a coordinate pair into this equation

25=50*1/10+b

25=5+b

b=20

hence y intercept is (0,20)

Given that,
To determine the number whose 62.5% is 2.25.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Given that,
Let the number be x,
According to the condition,
62.5% of x = 2.25
0.625x = 2.25
x = 2.25/0.625
x = 3.6


Thus, the required number whose 62.5% is 2.25 is given as 3.6.
