Answer:
8) x = 4°
9) $7176.53
10) 22
Step-by-step explanation:
8) The sum of all three interior angles of any triangle = 180°
11x + 25x + 9x = 180°
45x = 180°
divide both sides of the equation by 45:
x = 4°
9) ($6500 x 1.02) = 6630 x 1.02 = 6762.60 x1.02 = 6897.85 x 1.02 = 7035.81 x 1.02 = 7176.53
10) (2/5)(55) =110/5 = 22
(x, y) ----> (-x, y).
The y value stays the same but the x-value changes sign.
we have two points
(0,4) and (3,-1)
m=(-1-4)/(3-0)
m=-5/3
