Answer:
Step-by-step explanation:
The number of miles that he ran last week is m.
His goal this week was to run one mile more than twice the miles he ran last week. This means that his goal this week is
m + 2m = 3m
If he tripled his goal, it means that the number of miles that he ran this week would be
3 × 3m = 9m
An expression in simplest form to show how many more miles he ran this week compared to last week would be
9m - m = 8m
Answer:
2-11i
Step-by-step explanation:
-2-5i - (-4+6i)
Distribute the minus sign
-2-5i +4 -6i
Combine the real parts
-2+4 = 2
Combine the imaginary parts
-5i-6i = -11i
the complex number is
2-11i
The slope of CD is -3. Bc if it was 3 as in the answer above, then the so called "parallel" lines would intersect.
