If the two rational expressions that you want to add or subtract have the same denominator you just add/subtract the numerators which each other. When the denominators are not the same in all expressions that you want to add or subtract as in the example below you have to find a common denominator.

the point slope form of the equation of a line that passes through (8,4) and (0,2) is y-4=1/4(×-8) what is the slope intercept f
marissa [1.9K]

Answer:

\large\boxed{y=\dfrac{1}{4}x+2}

Step-by-step explanation:

The slope-intercept form of the equation of a line:

y=mx+b

m - slope

b - y-intercept → (0, b)

The point-slope form of the equation of a line:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

We have the equation of a line:

y-4=\dfrac{1}{4}(x-8)\to m=\dfrac{1}{4}

and the point (0, 2) → b = 2.

Substitute:

y=\dfrac{1}{4}x+2

A coin toss is used to determine which team will receive the ball at the beginning of a football game.

The Cougars always choose tails in the toss.

There will total of 8 cases and in 8 cases there will be three cases in which exactly two heads will come so,

3:8

The cases = {TTT, TTH, THT, HTT, HHT, HTH, HHT, HHH}

Thus, the odds in favor of the Cougars losing the toss in exactly two of three games is 3:8 option second is correct.
