So basically, the input value is x and the output value is y. In this problem, you have to find the x value that is equal to 2 for the y value. So if you look on the graph, you will find that when x = -2, then y will equal 2.

Therefore, the input value is -2.

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.

What is the recursive formula for 100, 80, 64, 51.2?
bonufazy [111]

From 100 to 80 is 8/10, so the recursive formula is

an=a(n-1)*1/8

or

an= a1*1/8(n-1)

an=a1*(n-1)/8

Solve the following system of equations by the substitution method.
Dahasolnce [82]

Answer:

Step-by-step explanation:

5x=y+6   --------- equ 1

2x-3y=4  -------- equ 2

5x - 6 = y

y = 5x - 6

substitute in equ 2

2x-3(5x - 6) =4

2x - 3*5x + 3*6 = 4

2x - 15x + 18 = 4

- 13x = 4 - 18

-13x = -14

x = -14/-13

x = 14/13

substitute  in equ 1

5*14/13 = y+6  

70/13 - 6 = y

y =  ( 70 - 78)/13

y = -8/13
