Y varies directly as x , y= 25 when x=5. Determine y when x= 13

Answers

Answer:

y = 65 when x = 13

Step-by-step explanation:

Here we have a proportion problem.

Y varies directly as x means that y equals the product of x and a constant

Let’s say our constant is k

Thus;

y = kx

now, k = y/x

Using the initial values;

k = 25/5 = 5

Now we want to get y when x = 13

Recall; y = kx

Thus using the value of k earlier calculated;

y = 13 * 5

y = 65

a. R = I ÷ E
b. R = EI
c. R = IE
d. R = E ÷ I

Answers

E= I x R divide I from both sides
E/I = R or R = E/I which is D in the answer selection.
Your answer is D. I hope this helps

11. If f(x)=4x-9, what is the equation for f^-1(x)?

Answers

f(x) = 4x - 9

let f(x) = y, this implies that  x = f⁻¹(y)

y = 4x - 9           Let us solve for x.

4x - 9 = y

4x = y + 9

x = (y + 9)/4

Recall that x = f⁻¹(y),

x = (y + 9)/4

f⁻¹(y) = (y + 9)/4

That means that for f⁻¹(x)

f⁻¹(x) = (x + 9)/4

Hope this explains it.
