If f:X is 3x + b and ff(2) = 12, find the value of b​
Tamiku [17]

Answer:

b =6

Step-by-step explanation:

Given

f(x) =3x + b

f(2) = 12

Required

Find b

f(2) = 12 implies that:

12 = 3 * 2 + b

12 = 6 + b

Collect like terms

b = 12 - 6

b =6

Yis inversely proportional to the square of x.
PtichkaEL [24]

Answer:

(a) y = \frac{4}{x^2}

(b) x = \frac{2}{5}

Step-by-step explanation:

Given

Variation: Inverse proportional.

This is represented as:

y\ \alpha\ \frac{1}{x^2}

See attachment for table

Solving (a):

First convert variation to equation

y = k\frac{1}{x^2}

From the table:

(x,y) = (1,4)

So, we have:

4 = k * \frac{1}{1^2}

4 = k * \frac{1}{1}

4 = k * 1

4 = k

k = 4

Substitute 4 for k in y = k\frac{1}{x^2}

y = 4 * \frac{1}{x^2}

y = \frac{4}{x^2}

Solving (b): x when y = 25.

Substitute 25 for y in y = \frac{4}{x^2}

25 = \frac{4}{x^2}

Cross Multiply

25 * x^2 = 4

Divide through by 25

x^2 = \frac{4}{25}

Take positive square roots of both sides

x = \sqrt{\frac{4}{25}

x = \frac{2}{5}
