A system of equations means that both equations need to be true in the same time.
Since y is equal with 3x-7 and 2x+7 then those must be equal with eachother.
3x-7=2x+7
3x-2x=7+7
X=14
Now that we know x use any given equation of y and substitute x with 14
Y=3•14-7=35
Solution: x=14, y=35

Step-by-step explanation: there the even ones
is irrational
A rational number can be expressed in the form
where a, b ∈ Z ( integers )
is in this form → rational
cannot be expressed in this form → irrational
is in this form → rational
= ± 3 and
, -
→ rational
Answer:
I believe Henrey is wrong
Step-by-step explanation:
because the roots of the quadratic function are
