Solution for F(x)=6x^2-900 equation:
<span>Simplifying
F(x) = 6x2 + -900
Multiply F * x
xF = 6x2 + -900
Reorder the terms:
xF = -900 + 6x2
Solving
xF = -900 + 6x2
Solving for variable 'x'.
Reorder the terms:
900 + xF + -6x2 = -900 + 6x2 + 900 + -6x2
Reorder the terms:
900 + xF + -6x2 = -900 + 900 + 6x2 + -6x2
Combine like terms: -900 + 900 = 0
900 + xF + -6x2 = 0 + 6x2 + -6x2
900 + xF + -6x2 = 6x2 + -6x2
Combine like terms: 6x2 + -6x2 = 0
900 + xF + -6x2 = 0 </span>
Hi Andres,
----------------------------------------
Coordinates:
(6,12) and (3,21)
----------------------------------------
Slope:
Formula: 
Solution: 
Slope: -3
----------------------------------------
Compute the y intercept:
Use: y = mx + b
y = (-3)x + b
12 = (-3) x 6 + b
----------------------------------------
Isolate b:
(-3) x 6 + b = 12
-3 x 6 + b = 12
-18 + b = 12
b = 30
----------------------------------------
Slope Intercept Form:
Follow y = mx + b
m = slope
b = y intercept
Answer: y = -3x + 30
----------------------------------------
Point Intercept Form:
Formula: y - y1 = m(x - x1)
m = slope
y1 and x1 = first coordinate set.
m = -3
y1 = 12
x1 = 6
Answer: y - 12 = -3(x - 6)
----------------------------------------
Part B:
Approximately for every day he spends delivering he spends a 2.1 minutes on it per day. Well, the reason I say this is because on the chart it says he spends 10 days. When you multiply 10 and 2.1 you get 21!

Answer:
(7x + 14)° = 84°
(15x - 4)° = 146°
Step-by-step explanation:
62° + (7x + 14)° = (15x - 4)°
62° +7x + 14 = 15x - 4
15x - 7x = 62 + 14 + 4
8x = 80
x = 10
Therefore, exterior angle (15x - 4)° = 146°
interior angle (7x + 14)° = 84°
