Answer:
y - 2 = 3(x - 2)
Step-by-step explanation:
Hello!
Please consider using the point-slope formula for the equation of a straight line, because in this case it's the easiest way to go.
(2,2) is one point on the line, and the slope is m = -3.
Thus, y - k = m(x - h) becomes y - 2 = 3(x - 2).
Answer:
Step-by-step explanation:
We khow that the genetic mutation affect 2 percent of the population .
Let's try to understand what does this mean :
- in a group of 100 people there is possibility of finding 2 people with this genetic mutation
- in a group of 1000 the possibility raises to 20 people so we can deduce that each time we add a zero we add a zero in 2
so :
- 100⇒2
- 1000⇒20
- 10000⇒200
- 100000⇒2000
and so on
Answer:
{10,8}
Step-by-step explanation:
-3x + 4y = -62
4x + 5y = 0
let's eliminate the x
-3x + 4y = -62 | x -4 |
4x + 5y = 0 | x 3 |
12x - 16y = 248
12x + 15y = 0
-------------------- -
-31y = 248
y = 248/(-31) = 8
since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)
-3x + 4y = -62 | x 5 |
4x + 5y = 0 | x 4 |
-15x + 20y = -310
16x + 20y = 0
-------------------- -
-31x = -310
x = -310/-31 = 10
