Answer:
f(x)=3(x)+5
f(x+2)=3(x+2)+5
=3x+6+5
=3x+11

Step-by-step explanation:
Outcomes of the spinner: 2, 3
Outcomes of the die: 1, 2, 3, 4, 5, 6
Add 2 to 1, 2, 3, 4, 5, 6 to get:
3, 4, 5, 6, 7, 8
Add 3 to 1, 2, 3, 4, 5, 6:
4, 5, 6, 7, 8, 9
All different sums:
3, 4, 5, 6, 7, 8, 9
Answer: 7
$136
∠ ABD = 49°, ∠ CBD = 28°
∠ ABD + ∠ CBD = ∠ ABC , substitute values
3x + 22 + 5x - 17 = 77 , that is
8x + 5 = 77 ( subtract 5 from both sides )
8x = 72 ( divide both sides by 8 )
x = 9
Thus
∠ ABD = 3x + 22 = 3(9) + 22 = 27 + 22 = 49°
∠ CBD = 5x - 17 = 5(9) - 17 = 45 - 17 = 28°
