Solving rational equations<br><br> solve for x: 3/x-4=7/x
KIM [24]

Solving the rational equation \frac{3}{x-4}=\frac{7}{x} the value of x is 7

Step-by-step explanation:

We need to solve rational equation: \frac{3}{x-4}=\frac{7}{x} and find value of x.

Solving:

\frac{3}{x-4}=\frac{7}{x}

Cross multiplying:

3(x)=7(x-4)\\Simplifying:\\3x=7x-28\\3x-7x=-28\\-4x=-28\\x=-28/-4\\x=7

So, value of x = 7.

Solving the rational equation \frac{3}{x-4}=\frac{7}{x} the value of x is 7

Which function has the greatest rate of exponential growth?
Veronika [31]

Answer:

C

Step-by-step explanation:

Here, we want to find which of the expressions have the greatest rate of exponential growth.

The easiest way to go about this is have a substitution for the term t;

Let’s say t = 6

Thus;

h(t) = 1.18^1 = 1.18

K(t) = 0.375^6 = 0.002780914307

f(t) = 1.36^6 = 6.327518887936

g(t) = 0.86^6 = 0.404567235136

Another way to find this is to express each as a sum of 1

f(t) = (1+ 0.36)^t

g(t) = (1-0.14)^t

k(t) = (1-0.625)^t

We can see clearly that out of all the terms in the brackets asides 1, 0.36 is the biggest in value
