Answer:

Step-by-step explanation:
The given function is

Which can be rewritten also as

We want to find the values of x for which

In order to do that, we just substitute -12 into f(x), and we solve the equation for x:

<span>A. Lines that go up from left to right should have a positive slope.
B. Lines that go down from left to right should have a negative slope.
</span><span>D. The slope of a steep line should be bigger than the slope of a flat line.
E. The slope of a steep line should be smaller than the slope of a flat line.</span>
Answer: 20 grams
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The amount of grams of silver he lost at the Holdong mine heist(x) plus 5 , is equal to the amount of grams of silver he lost in the Hysean mine heist. (25)
