Answer:
D
Step-by-step explanation:
Associative Property of Multiplication is a(bc) = (ab)c
d is the only one that follows the rule
I need more information to answer that.
7x - 2y = -3 . . . (1)
14x + y = 14 . . . (2)
(1) x 2 => 14x - 4y = -6 . . . (3)
(2) - (3) => 5y = 20
y = 20/5 = 4
From (1); 7x - 2(4) = -3
7x - 8 = -3
7x = -3 + 8 = 5
x = 5/7
Solution = (5/7, 4)
Answer: how about 90
Step-by-step explanation:
Its a 360 if you multiply 90×4 you get 360 every side is 90 degrees
Y = yo + Vot - (gt^2)/2
y = 10 + 27t - 16.087t^2 [I used g = 32.174 ft/s^2]
You can find y with the quadratic formula or probe with the different times given.
I tried with t = 2 s and found
y = 10 + 27(2) - 16.087 (4) = 10 + 54 - 64.348 = -0.348
Then that is the answer, t = 2s.
