The least common multiple is 32
M = (8-2)/(4-2) = 3
Therefore the slope is 3 (D).
Answer:
the third selection is corret
Step-by-step explanation:
Ax + by + c = 0, k = - a/b.
so The slope of the first line = 
,
the slope of the second line = ;
So these two lines are parallel and they don't intersect
Answer:
y = -0.25x + 10
Step-by-step explanation:
Point-slope form is y - y1 = m (x - x1)
Here, y1 is 7, m is -0.25, and x1 is 12
When you plug these values in, you get y - 7 = -0.25 (x - 12)
Now we have to solve for y.
y - 7 = -0.25 (x - 12)
Distribute
y - 7 = -0.25x + 3
Add 7 to both sides
y = -0.25x + 10
Answer:
a) 675 000
b) 685 000
Step-by-step explanation:
The population of a town is 680 000 correct to the nearest 10 000.
a) To find it lower bound, we level of accuracy by 2 and then subtract from 680 000
The lower bound is:
680 000-5000=675,000
Therefore the least possible population of the town is 675 000
b) We repeat the same process to find the upper bound
680 000+5000=685,000
