Step-by-step explanation:
0.072338 in decimal form or just leave it as it is
1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.
Answer:
{x:x<3}
Step-by-step explanation:
You first change the < to = in order to simply it. Thus,
- 2x-5=1
- 2x=1+5( move the -5 to the right hand side to obtain 5)
- 2x= 6
- dividing through by 2
- 2x/2=6/2
x=3 . Therefore the solution is {x:x<3} <u>sing you didn't divide with a</u> <u>negative number ,the < sing remains unchanged</u>
