Setler79 [48]

Answer:

x = 6

Step-by-step explanation:

We want to find x,

\frac{3}{5} = \frac{x}{10}

to get x alone, we multiple both side by 10

\frac{3}{5} * 10 = \frac{x}{10} *10

\frac{30}{5} = x

30 divided by 5 is 6

<u>Check</u>:

We can see that 5 x ____ = 10 where ____ is 2

5 x 2 = 10

so 3 x 2 = 6

brilliants [131]

Answer:

A= 4.5×10^11

B= 3.5×10^3

Step-by-step explanation:

A

(5×10^3)= 5000

(9×10^7)=90000000

multiply both of them

=450000000000 or 4.5×10^11

B

(7×10^5)=700000

(2×10^2)=200

700000÷200

3500 or 3.5×10^3

Given f of x is equal to the quantity x plus 3 end quantity over the quantity x squared minus x minus 12 end quantity and g(x) =
Westkost [7]

From the given f(x) and g(x), the value of (g-f)(2)=1

Given :

The functions are

f(x)=\frac{x+3}{x^2-x-12} \\g(x)=log_4(x)

Lets evaluate (g-f)(2)

(g-f)(2)=g(2)-f(2)

To find out g(2), replace 2 for x  in g(x) and then replace 2 for x in f(x)

f(x)=\frac{x+3}{x^2-x-12} \\g(x)=log_4(x)\\x=2\\f(2)=\frac{2+3}{2^2-2-12}=\frac{5}{-10}=-\frac{1}{2}  \\\\g(2)=log_4(2)=\frac{1}{2}

Now we find g(2)-f(2)

(g-f)(2)=g(2)-f(2)=\frac{1}{2}-\frac{-1}{2}  =1
