Answer:
5-2x=12
-5. -5
-2x=7 so ans shld be -2x=7
Answer:
the balance would be 48000
Step-by-step explanation:
First you really dont have to do with the 3.9%
If 4000 is invested and you need the balance after 12 years you just multiply
4000 times 12=48000
Answer:
No solutions
Step-by-step explanation:
5(x-2)=5x-7
5x-10 = 5x-7
When you try to solve this equation, you end up cancelling out the 5x on both sides, which means you cannot solve for x, so there are no solutions.
In conclusion, these are two parallel lines, since they have the same slope with different y intercepts.
Just make the equations equal to each other. -0.5x+5=3x-2. Solve for x and find that it is 2, via simple algebra. Since you know x is 2, sub it in in either equation to find y. y should be 4. So the point that fits both equation is (2,4). This shows that the two graphs of these lines will intersect at this exact point.
If you were to graph these two lines, you ould see that the point of intersection is at (2,4) like we solved for.
