Answer:
(A) 
Step-by-step explanation:
Slope intercept form of equation of line is 
The standard form of equation is 
Now let 
substituting the value of A and B in slope intercept form,

Answer: -25
Since x=-3, y=6, and z=-4 you have to plug those numbers into the corresponding varibale in the equation. So 3x becomes 3(-3) because x=-3, 2y becomes 2(6) because y=6 and z becomes just -4. The whole equation comes to 3(-3)- 2(6)+(-4)= -25
A) 30 mi. north for 30 min - 15 miles traveled
B) 60 mi. east for 1.0 hour - 60 miles traveled
75 miles traveled for 1.5 hours = 50 mph
We have the following functions:
f (x) = x3 - 3x2 - 13x + 15
f (x) = x4 + 3x3 - 8x2 + 5x - 25
f (x) = x3 - 2x2 - x + 2
f (x) = -x3 + 13x - 12
Factoring we have:
f (x) = x3 - 3x2 - 13x + 15 -------> x + 3
f (x) = x4 + 3x3 - 8x2 + 5x - 25 -> x + 5
f (x) = x3 - 2x2 - x + 2 ------------> x - 2
f (x) = -x3 + 13x - 12 -------------> x + 4
Yes because there isn't a decimal or fraction
