Answer:

  • 10m + 7n - 14

Step-by-step explanation:

<u>Given</u>

  • Q = 7m + 3n,
  • R = 11 - 2m,
  • S = n + 5,
  • T = -m - 3n + 8

<u>Simplify [Q - R] + [S - T]</u>

  • (7m + 3n - (11 - 2m)) + (n + 5 - (-m - 3n + 8)) =
  • 7m + 3n -11 + 2m + n + 5 + m + 3n - 8 =
  • m(7 + 2 + 1) + n(3 + 1 + 3) - 14 =
  • 10m + 7n - 14

Answer:

\huge\boxed{r_{x-axis}(x,\ y)\to(x,\ -y)}

Step-by-step explanation:

Read the coordinates of the points:

A(-1, 0) → A'(-1, 0)

B(0, 2) → B'(0, -2)

C(3, 2) → C'(3, -2)

D(4, 0) → D'(4, 0)

(x, y) → (x, -y)

Check:

A → A': (-1, 0) → (-1, -0) = (-1, 0)    CORRECT

B → B': (0, 2) → (0, -2)      CORRECT

C → C': (3, 2) → (3, -2)        CORRECT

D → D': (4, 0) → (4, -0) = (4, 0)     CORRECT
