If f(x) is linear, f(− 1) = 9 , and f(2) =− 24, find f(x).
professor190 [17]

Answer: Equation of st line is Y= -9X + 141

Step-by-step explanation: Given Y= 24 when X = 13 and Y = 87 when X = 6

Let the equation be Y = mX + C

24 = m*13 +C

and 87 = m* 6 +C

Give m = -9 and C = 141

Equation of st line is Y= -9X + 141

Answer:

y = 12

Step-by-step explanation:

Looking at the large triangle

tan 30 = opposite / adjacent

tan 30 = 4 sqrt(3)/ y

Multiply each side by y

y tan 30 = 4 sqrt (3)

We know tan 30 = sqrt(3)/3

y * sqrt(3)/3 = 4 sqrt(3)

Multiply each side by 3/ sqrt(3) to isolate y

y * sqrt(3)/3 * 3/ sqrt(3) = 4 sqrt(3) * 3 /sqrt(3)

y = 12

chubhunter [2.5K]

Answer:

13/100

Step-by-step explanation:

we know that

The probability of the event occurring plus the probability of the event not occurring must equal to 1

If the probability that a pupil in a class has a calculator is 0.87

then

The probability that the pupil does not have a calculator is equal to

1-0.87=0.13

Convert to fraction

0.13=\frac{13}{100}
