Answer 1

D

Explanation:

So we want to evaluate the expression:

`-1\cdot f(-9)+7\cdotg(6)`

First, let's figure out the value of f(-9) and g(6).

From the graph, we can see that a point on f(x) is (-9,4). In other words, f(-9)=4.

Also, a point on g(x) is (6,6). This means that g(6)=6.

Substitute:

`=-1\cdot(4)+7\cdot(6)`

Multiply:

`=-4+42`

Add:

`=38`

So the answer is D.

And we're done!
