Answer:
x=0
Step-by-step explanation:
Anything divided by 0 is undefined so in this case 1/0 would be undefined.
Answer:
C) The solution for the given system of equations are A(0,-5) and B(-4,3)
Step-by-step explanation:
The given system of equation are : 
from equation 2, we get y = -5 - 2x .
Put the above value of y in the equation (1).
We get: 
By ALGEBRAIC IDENTITY:

or, 
or, 
⇒ x = 0 or, x = -20/5 = -4
So, the possible values for x are: x = 0 or x = -4
If x = 0, y = -5-2x = -5-2(0) = -5
and if x = -4, y = -5 -2(-4) = -5 + 8 = 3
Hence, the solution for the given system of equations are A(0,-5) and B(-4,3)
Answer:
7.
Step-by-step explanation:
-10 /(3 + 2) + 9
= -10 /5 + 9
= -2 + 9
= 7.
Answer:
142.50
Step-by-step explanation:
28.50=1 hour so you would do 28.50 times the amount of hours she works. She worked 51 hours so you would do 28.50x50. You answer is 142.50
