Answer:

The answer is "2"

Step-by-step explanation:

When we check the points where the x is -2

by calculating the "y-value":

It is 2, right?

it implies that $f(-2)=2$

that's why the final answer is "2"

What is the equation of the line whose slope is 3 that passes through the point (-1, 5).

sergey [27]

We knownthe equation of a line is y = mx + b. where m is slope and b is y intercept.

the point slope equation of a line is y - y1 = m (x - x1)

plug in x1 and y1 and m
y- (5) = (3)(x - (-1))
y - 5 = 3x + 3
y = 3x + 8

Answer:

Sample space=S={HH1,HT1,TH1,HH2,HT2,TH2,HH3,HT3,TH3,HH4,HT4,TH4}

Step-by-step explanation:

The sample space for Y can be made as under

Coin is tossed two times={HH,HT,TH,TT}

4-sided die is rolled={1,2,3,4}

Coin is tossed two times and 4-sided die is rolled

={HH1,HT1,TH1,TT1,HH2,HT2,TH2,TT2,HH3,HT3,TH3,TT3,HH4,HT4,TH4,TT4}

Y be the random variable that the number of heads observed multiply by die roll number so, the sample space for Y would be

Sample space=S={HH1,HT1,TH1,HH2,HT2,TH2,HH3,HT3,TH3,HH4,HT4,TH4}
