Simplifying rational expressions will make the further calculations easier since the variables to work with will usually be smaller.
To determine that a rational expression is in simplest form we need to make sure that the numerator and the denominator have no common variables.
No. The points don’t connect in a Straight line
Answer:
(- 1, 2 )
Step-by-step explanation:
Given the 2 equations
2x + 5y = 8 → (1)
- x + 3y = 7 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the term in x, thus
- 2x + 6y = 14 → (3)
Add (1) and (3) term by term to eliminate the x- term
11y = 22 ( divide both sides by 11 )
y = 2
Substitute y = 2 in either of the 2 equations and evaluate for x
Substituting in (1)
2x + 5(2) = 8
2x + 10 = 8 ( subtract 10 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Solution is (- 1, 2 )
Oops for Jerry. Don't let this happen to you!
An overdrawn account by $15 is a negative $15. When you add the $10 service charge, you now have negative $25. When you add your $60, you will only have the difference between $25 and $60 left in the account.
It looks like this:
-$15 + $60 = ?
60 - 15 = 45 dollars in the account.
Good news for Jerry. My bank charges $35 service charge to be overdrawn. (Don't ask me how I know this...)
No I suck at math sorry bEsTiE
