Answer:
The answer is B. x < 1
Step-by-step explanation:
The point-slope form:

We have the slope m = -2/3 and the point (-9, 3). Substitute:

<em>use distributive property</em>


<em>add 3 to both sides</em>


so.. .whatever those amounts are, of "x" and "y", for the mixture,
they must add up to 100 grams, or x + y = 100
and the titanium percentage of that sum, must yield a 13 grams of titanium on those 100 grams
thus

do the substitution, and solve for "x",
what's "y" amount? well, y = 100 - x
