Answer:
The solution is (-2, 0)
Step-by-step explanation:
Re-write -2x=-y+4 x=-2 in column form:
x=-2
-2x=-y+4
Next, substitute -2 for x in the second equation:
-2(-2) = -y + 4, or:
4 = -y + 4. Thus, y must be 0.
The solution is (-2, 0)
Answer:
99$
Step-by-step explanation:
you take the 5.25$ per hour and multiply it by the 15 hours, and then you add the 20.25$ per month
2x^2+9x-6 i found this by subtracting 3x^2+7x from the other equation
Answer:
![y\in (-\infty ,5]](https://tex.z-dn.net/?f=y%5Cin%20%28-%5Cinfty%20%2C5%5D)
Step-by-step explanation:
In this problem, we need to write "Twenty times y is at most 100 in interval notation
".
20 times y means, 20y
Atmost means an inequality which is 
ATQ,
i.e.
We can also write it as :
Hence, the required interval notation is .
