Which of the following best approximates the value g(h(1))?

34kurt

Answer:

Option (B)

Step-by-step explanation:

From the graph attached,

There are two functions 'f' and 'g' graphed.

Value of the function 'h' at x = 1,

y = h(1) = 0

Now we know g[h(1)] = g(0) [By substituting the value of h(1) = 0]

Therefore, value of the function 'g' at x = 0,

y = g(0) = -5 [y-intercept at x = 0]

Option (B) will be the correct option.

What is the value of y in the following system? y=3x-5 6x+3y=15

charle [14.2K]

Step-by-step explanation:

y=3x-5

6x+3y=15

6x+3(3x-5)=15

6x+9x-15=15

15x-15=15

+15 +15

15x=30

/15. /15

x=2

6(2)+3y=15

12+3y=15

-12. -12

3y=3

/3 /3

y=1

(2,1)

The answer is (2,1)
