How can 2x2 = x2 + 4x + 8 be set up as a system of equations?

y = x2 - 4
y = x2 + 2x + 8

y = x2
y = x2 + 4x + 8

y = 2x2
y = x2 + 4x + 8

y = x2
y = 2x + 8

Step-by-step explanation:

we have

-----> original equation

To set up as a system of equations

Let the left side of the equation ------> equation A

Let the right side of the equation ------> equation B

so

-------> equation A

-----> equation B

The system of equations will have the same solutions for x that the original equation

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
