Answer:
-a^2 - a + 12
Step-by-step explanation:
You only need to find the products of the first and last terms to determine the correct answer:
(-a)(a) = -a^2
(3)(4) = 12
You're looking for an expression with -1 as the leading coefficient and +12 as the constant. There is only one choice like that:
-a^2 - a + 12
Answer:
so u will pay 3.82 and u will save 15.26 dollars
Step-by-step explanation:
the scale is x4
because 10x4=40
11x4=44
18x4=72
you multiply by 4 on all of them
-5/1 is the slope so the answer is -5 because you pick 2 points and use point slope formula or
y1-y2/x1-x2
