Step-by-step explanation:
x = 2 , y = 7
ans, y = 11 - 2x and 4x - 3y = -13
→ 7 = 11 - 2(2) → 7 = 11 - 4 → 7 = 7
→ 4(2) - 3(7) = -13 → 8 - 21 = -13 → -13 = -13
x = 5 , y = 2
→ 2x + y = 12 and x = 9 - 2y
as, 2(5) + 2 = 12 → 10 + 2 = 12 → 12 = 12
x = 9 - 2y → 5 = 9 - 2(4) → 5 = 9 - 4 → 5 = 5
x = 3 , y = 5
ans. 2x + y = 11 , x - 2y = -7
2(3) + 5 = 11 → 6 + 5 = 11 → 11 = 11
3 - 2(5) = 7 → 3 - 10 = 7 → 7 = 7
x = 7 , y = 3
ans. x + 3y = 16 and 2x - y = 11
7 + 3(3) = 16 → 7 + 9 = 16 → 16 = 16
2(7) - 3 = 11 → 14 - 3 = 11 → 11 = 11

Answer:
f (x) = x2 shows us that function " f " takes " x " and squares it. Example: with f (x) = x2: becomes an output of 16. In fact we can write f (4) = 16. The "x" is Just a Place-Holder! Don't get too concerned about "x", it is just there to show us where the input goes and what happens to it.
Answer:
x - 2y = 2
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and A, B are integers )
given y = x - 1
multiply through by 2 to eliminate the fraction
2y = x - 2 ( subtract 2y from both sides )
0 = x - 2y - 2 ( add 2 to both sides )
x - 2y = 2 ← in standard form
Answer:
38x - 7
Step-by-step explanation:
x^2 is 2x
2x +36x is 38x
38x -42 cant be done so you leave it
42 divided by 6 is 7
