X^2+81=4x^2
3x^2=81
x^2=27
x=(27)^0.5
Answer:
slope = 7 and point = (3, 7)
b = y - slope*x
b = 7 -7 * 3
b = -14
Then we enter "b" and the slope into this equation:
y = 7x -14
Step-by-step explanation:
Answer:
x(x - 1 ) = 0
Step-by-step explanation:
x^2 - x + 3 = 3
subtract 3 from each side:
x^2 - x = 0
x(x - 1 ) = 0
Cos²(15°) - sin²(15°) = cos(15° * 2) = √(3/2 so this is the answer by using apropriate formula double angle identity
No it cannot because 1.8 and 1.2 are both larger than 0.75 so there is no physical way for it to fit
