2nd one, y=2x+3
so subsitute y with 2x+3 in other equation

2x-(2x+3)=7
2x-2x-3=7
0-3=7
-3=7
false
no solution
(also, the slopes of the lines are the same and therefor they are paralell and differnet y intercepts so never intersect)


no solution

Answer:  The given system of equations will have NO solution.

Step-by-step explanation:  We are given to find the solution to the following system of linear equations :

2x-y=7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\y=2x+3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)

We will be solving the given system of equations by the method of SUBSTITUTION.

Substituting the value of y from equation (ii) in equation (i), we get

2x-y=7\\\\\Rightarrow 2x-(2x+3)=7\\\\\Rightarrow 2x-2x-3=7\\\\\Rightarrow -3=7,

which can NEVER be true.

Therefore, the given system of equations will have NO solution.

How is the scientific use of the term digital different from the common use
Mamont248 [21]
While “digital” commonly refers to electronics in general, the scientific definition of digital is much different. “Digital” in information science refers to the finite, discontinuous phenomenon (e.g., on or off states in a light bulb) as opposed to infinitely varying, continuous analog phenomenon (e.g., the brightness of daylight). It can also refer to representing data in figures as opposed to data represented in pictorial form.

A cellphone company charges $60 for a cellphone and a monthly rate to use the phone.Regina will pay $1,140 for a 24-month cellph
Alinara [238K]

The monthly rate is $45 for this cellphone plan.

Step-by-step explanation:

Given,

Amount charged for cell phone = $60

Amount paid by Regina for 24 month plan = $1140

Number of months = 24

Let,

m be the monthly rate for cellphone plan

Number of months * Monthly rate + cellphone charges = Amount paid

24m+60=1140\\24m=1140-60\\24m=1080

Dividing both sides by 24

\frac{24m}{24}=\frac{1080}{24}\\m=45

The monthly rate is $45 for this cellphone plan.
