Answer:
   (x, y) = (-3, -13) or (-8, -23)
Step-by-step explanation:
The values for y can be equated and the resulting quadratic solved by factoring.
   2x -7 = x^2 +13x +17
   0 = x^2 +11x +24 . . . . . . subtract 2x-7
   0 = (x +8)(x +3) . . . . . . . .factor*
The values of x that make these factors zero are x=-8 and x=-3. The corresponding values of y are ...
   y = 2(-8) -7 = -23
   y = 2(-3) -7 = -13
The solutions are ...
   (x, y) = (-8, -23) and (-3, -13)
_____
* The constants in the binomial factors are factors of 24 that total 11. You know that ...
   24 = 1×24 = 2×12 = 3×8 = 4×6
The sums of these factors are 25, 14, 11, 10. The factors 3 and 8 are the constants in the binomial factors of the quadratic.
"24" is the constant in the quadratic. "11" is the coefficient of the x term.

Answer:
63/9 = 7 -> Yes
-94 -> Yes
30/6 = 5 -> Yes
-16/3 ~ -5,33 -> Nope
-29,86 -> Nope
Step-by-step explanation:
Integers are whole Numbers.
For example 1,2,3,4,5...
The numbers between numbers are rational numbers.
Fir example:
1,2 ( between 1 and 2)
3,8 (between 3 and 4)
2,6 (between 2 and 3)

Answer:
  5
Step-by-step explanation:
Put the numbers where the letters are and do the arithmetic.
   5(3) -2(5) = 15 -10 = 5
