2. Solve the equation below and find the variation constant, k. Find y when x= 18, if y varies directly as x, and y=37 when x=5 *Round your answer to the nearest thousandth, if necessary.

Step-by-step explanation:

To find the value of y when x= 18 we must first find the relationship between them

The statement

y varies directly as x is written as

where k is the constant of proportionality

when y = 37

x = 5

Substitute the values into the above formula and solve for k

That's

37 = 5k

Divide both sides by 5

So the formula for the variation is

When x = 18

y = 7.4(18)

We have the answer as

Hope this helps you

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
