Multiplying both sides of a rational equation by a variable expression introduces the possibility of extraneous solutions. Therefore, we must check the solutions against the set of restrictions. If a solution is a restriction, then it is not part of the domain and is extraneous.
Answer:
56
Step-by-step explanation:
Answer:
9 times 59 is 531. 531+240= 771 she needs to work 59 hours.
Step-by-step explanation:
Y = -2 x - 9
3 x - 4(-2 x - 9 ) = -8
3 x + 8 x + 36 = - 8
11 x = - 44, x = - 4
y = 8 - 9 , y = -1
This is a unique solution, the system is independent.
10. x*x + 10x + 21 = x + 3 * length
11. x*x + 2x - 8 = x + 4 * breadth
This is the expression bro!
100% sure
