Find the value of x. A) x = 60 B) x = 59 C) x = 121 D) x = 177

1 answer:

7 0

Since a triangle always equals 180 degrees, set all these variables equal to 180.
Lets try.
X+3+x+x= 180
Combine like terms
3x+3= 180
Subtract each side by 3
3x=177
Divide each side by 3
X= 59

Answer:

Step-by-step explanation:

The order of operations tells you to start any evaluation by looking at the innermost set of parentheses first.

Here, that means your first step is to find the value of h(-3). You do that by finding the input (x) value -3 in the table for h(x), and locating the corresponding output, h(x), which is 2.

Now, the problem becomes evaluating g(2).

You do the same thing for that function: locate the input x=2 in the table for g(x) and find the corresponding output: 7.

Now, you know ...

g(h(-3)) = g(2) = 7
