6x^2 is the correct answer to the problem.
Answer:
Yes
Step-by-step explanation:
To see is (2, 6) is a system, we can plug it into the system to check if it gives us true statements:
6 = -2+8
6 = 6
6 = 5(2)-4
6 = 10-4
6 = 6
Both of the equations are true, therefore (2, 6) is a solution to this system.
I believe the answers is 11
Answer:
1.2 x 10⁴
Step-by-step explanation:
12,000 has 2 places of other numbers before a spam of zeroes.
Take the numbers before zeroes and put a decimal to the left of the last digit.
Last digit is 2 so a decimal goes before 2
1.2
Count how many places the decimal moved: this number is your power of 10.
12000. --> 1.2000
It moved 4 places.
12,000 = 1.2 x 10⁴
Answer:
Step-by-step explanation:
h = −16(x − 2)² + 72
= −16((x − 2)(x − 2)) + 72 expand the square (x - 2)² = (x - 2)(x - x)
= -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72
= -16 (x² + (-2x) + (-2x) + (4) ) + 72
= -16 (x² + (-4x) + (4) ) + 72
= -16 (x² - 4x + 4 ) + 72
= (-16)(x²) + (-16)(-4x) +(-16)(4) + 72
= -16x² + 64x - 64 + 72
= -16x² + 64x + 8 My guess is D ; 72 ???
I have no clue what the ; 72 means after the given answer. It must be a standard form thing I never learned.
