Answer:
see explanation
Step-by-step explanation:
(a)
(x + 2)(x + 12) ← expand using FOIL gives
x² + 14x + 24 ≠ x² + 10x + 24
(b)
consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (+ 10)
the factors are + 6 and + 4 , since
6 × 4 = 24 and 6 + 4 = 10 , then
x² + 10x + 24 = (x + 6)(x + 4)
They are the same because if you convert 20/60 into decimal form its .33 plz rate my answer as brainliest
Answer:
See below ~
Step-by-step explanation:
<u>Option A</u>
- Unit Rate = $2.49 / 24
- Unit Rate = $1.04 per bottle
<u>Option B</u>
- Unit rate = $6.00 / 48
- Unit rate = $0.13 per bottle
<u>Option C</u>
- Unit rate = $1.86 / 12
- Unit rate = $0.16 per bottle
Option C has the lowest rate, hence it is the best deal.
The domain of the function is the range of values of x that can be used to be replaced in the equation for it to become true. We are given that the value of f(x) should range only from -1 to 3. We evaluate each of the choices and see if the values of f(x) will fall within the range.
(a) -12; f(x) = 2^(-12) - 10 = -9.9999 (NOT AN ANSWER)
(b) -10; f(x) = 2^(-10) - 10 = -9.999 (NOT AN ANSWER)
(c) -9; f(x) = 2^(-9) - 10 = -9.999 (NOT AN ANSWER)
(d) -6; f(x) = 2^(-6) - 10 = -9.98 (NOT AN ANSWER)
(e) -2; f(x) = 2^(-2) - 10 = -9.75 (NOT AN ANSWER)
Hence, none of the choices will allow the value of f(x) to fall between -1 and 3.
22/20 and 44/40 those are two
