Answer:
In this case, the factor that comes out is x=−3, so you would divide by (x+3). Repeat until you've reduced to a quadratic, and then use the quadratic formula to find the irrational coefficients (if any). Simple factorisation solves your problem. Hence the 4 roots are x=12,x=−3,x=2i and x=−2i.
Answer:
0.2379
Step-by-step explanation:
55 min/10 km=5.5 min/km
5.5 min/km x 1 km/.621 mile= 5.5/.621=8.86 min/mile
The answer is D.
Answer:
y = 
x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 3x + 4y = 16 ( add 3x to both sides )
4y = 3x + 16 ( divide all terms by 4 )
y = x + 4 ← in slope- intercept form
