9 or -9 because if -9 is squared the negative cancels
For the equation -1/2x+3y=-3
the x-intercept=6
the y-intercept=-1
To find this out multiply 2 * 2 * 2 * 2 to get 16 possible combinations
Answer:
-7/25.
Step-by-step explanation:
From the given point P we see that the hypotenuse = √(3*2 + 4^2) = 5.
So cos θ = 3/5
cos 2 θ = 2 cos^2 θ - 1
= 2 * (3/5)^2 -1
= -7/25.
Answer:
Step-by-step explanation:
el número es 4,5
es una ecuación lineal:
2x+18=27
2x=9
x=9/2
x=4,5
