Answer:

y = -2x - 5

Step-by-step explanation:

The given slope, or m, is -2 and the given y-intercept, or b, is -5.

The y-intercept equation is y = mx + b, so by knowing this equation all you need to do is plug in the given slope and y-intercept

y = -2x - 5

14. A unfair coin has the probability of heads

Hitman42 [59]

Answer :

the probability of tossing three heads in a row

$=\left( \frac{3}{8} \right)^{3} =\frac{27}{512} =0.052734375$

…………………………………………

the probability of tossing two heads followed by one tail

$=\left( \frac{3}{8} \right)^{2} \times \left( \frac{5}{8} \right) =\frac{45}{512}$

……………………………

the probability of two heads and one tail in any order

$=3\times \left( \frac{3}{8} \right)^{2} \times \left( \frac{5}{8} \right) =\frac{135}{512}$

lubasha [3.4K]

Answer:

x = (8+y)/3

Step-by-step explanation:

3x-y=8

Add y to each side

3x-y+y=8+y

3x = 8+y

Divide each side by 3

3x/3 = (8+y)/3

x = (8+y)/3
