Sara wants to find the input value that produces the same output for the functions represented by the tables.
Ipatiy [6.2K]

Answer:

2 is the value that provides the same result with f(x) and g(x).

Step-by-step explanation:

You can solve this by saying:

f(x) = g(x)

and then solving for x.

So let's do it:

f(x) = g(x)\\-0.5x + 2 = 2x - 3\\2x + 0.5x  = 2 + 3\\2.5x = 5\\x = 2

This tells us that when x = 2, the two functions will have identical values.  Let's try them out to confirm it!

f(x) = -0.5x + 2

f(2) = -0.5 * 2 + 2

f(2) = -1 + 2

f(2) = 1

g(x) = 2x - 3

g(2) = 2 * 2 - 3

g(2) = 4 - 3

g(2) = 1

So we can see that 2 is the value that produces the same result in both charts.

x=280

Step-by-step explanation:

We have, 15% × x = 42

or,

15

100

× x = 42

Multiplying both sides by 100 and dividing both sides by 15,

we have x = 42 ×

100

15

x = 280

If you are using a calculator, simply enter 42×100÷15, which will give you the answer.
