Answer:
John can use no more than 2 GB of additional data
Step-by-step explanation:
Monthly fee = $40
Additional fee = $15 for each 1 GB of data (rounded up) over his 8 GB.
Let x be the number of additional data in GB over his 8 GB of data that comes with his plan.
Total monthly charge is

It is given that monthly charge before taxes to be at most $70.




Divide both sides by 2.

Therefore, John can use no more than 2 GB of additional data.
Factored form refers to the form of a number or algebraic expression when it has been broken down into a product of its factors
Standard form is a way of writing down very large or very small numbers easily.
Answer:
B=(EF-Ax)/y
Step-by-step explanation:
Ax+By=EF
By=EF-Ax
B=(EF-Ax)/y
substitute the ordered pair (2, 3 ) into the 2 equations
(3 × 2 ) + (4 × 3 ) = 6 + 12 = 18 → True
(2 × 2 ) - (2 × 3 ) = 4 - 6 = - 2 → False
Hence the ordered pair (2, 3 ) is not a solution to the system of linear equations.
When (2, 3 ) is substituted into the first equation, the equation is true.
When (2, 3 ) is substituted into the second equation, the equation is false.
This transformation is called a rotation:-D
