Answer:
C. [Sorry if it's wrong.]
Step-by-step explanation:
I haven't taken this test but when looking at the photo, it looked like they intercepted at (0, 2).
A foot is 12 inches.
3 inches divided by 12 inches = 3/12 or 1/4 of a foot.
12. I need the graphs to answer it
11. y = 1/2x - 1
10. The first graph is the best
Answer:
x = ± 3, x = ± 2i
Step-by-step explanation:
Given
f(x) = (x² + 4)(x² - 9)
To find the zeros let f(x) = 0, that is
(x² + 4)(x² - 9) = 0
Equate each factor to zero and solve for x
x² - 9 = 0 ( add 9 to both sides )
x² = 9 ( take the square root of both sides )
x = ± = ± 3
x² + 4 = 0 ( subtract 4 from both sides )
x² = - 4 ( take the square root of both sides )
x = ± = ± = ± × = ± 2i
Thus zeros are
x = - 3, x = 3 ← real
x = - 2i, x = 2i ← complex
I'm not great with math, but if the peanut butter is $4.00 and it is on sale for $3.60 it is 40 cents off... the answer would be 10%.
To check your answer, you know that 10% is .10 as a decimal. $4.00 * .10 = .40cents, then $4.00 - .40 = $3.60
