Answer:
Step-by-step explanation:
The total cost would be "Y".
"x" is would be "per text message".
12 cents per text message would be .12x.
And then, on top of that, we have to pay $30 per month. ( + 30 )
Put together, the equation should be y = .12x + 30.
Answer:
A nonlinear system of inequalities consists of two or more inequalities. At least one of these is/are nonlinear
Step-by-step explanation:
System of non-linear inequalities--
A system of non-linear inequalities is a system of inequalities consisting of two or more variables such that it contain at least one inequality which is non-linear.
The difference between the system of linear inequalities and a system of non-linear inequalities is it may cover more region of the solution as compared to system of linear inequalities.
What I would do:
5x + 10y = 35
Divide everything by 5.
x + 2y = 7
x = 7 - 2y
Now plug "x" into either one of the equations.
2(7-2y) + 5y = 15
14 - 4y + 5y = 15
14 + y = 15
y = 1
Now, solve for x by plugging in y into either one of the equations.
2x + 5y = 15
2x + 5 =15
2x = 10
x = 5
So x is 5 and y is 1.
Check by plugging in the values into the other equation.
5x + 10y = 35
5(5) + 10(1) = 35
25 + 10 = 35
35 = 35
The values are correct so, the answer for this problem is B (5, 1).
