Answer:
x=25°, y=10°
Step-by-step explanation:
∠A+∠B=180°
8y+10y=180°
18y=180°
y=10°
∠B+∠C=180°
10y+4x-20°=180°
10*10°+4x=180°+20° (y=10°)
100°+4x=200°
4x=200°-100°
4x=100°
x=25°
H (x) = 5x^2+40x+64
y = (5x^2+40x+60) + 4
y = 5(x^2+8x+12) + 4
y = 5(x+2)(x+6) + 4
y-4 = 5(x+2)(x+6)
This means that the solutions, or where the parabola crosses the x-axis, are at x+2=0 and x+6=0, or x=-2, -6
So the midpoint of -2 and -6 is -4, the axis of symmetry is x=-4

Answer:
$875.39
Step-by-step explanation:
1) Divide the tax rate (6.500%) by 100 to get a decimal rate of 0.06500.
2) Multiply the purchase price ($821.95) by the 0.06500 to get a sales tax amount of $53.43.
3) Add the $53.43 sales tax to the $821.95 price to get a total of $875.38.
4) Round $875.38
