I hope this helps!
x = 3 is the answer can you pls add me brainliest answer
Answer:
X = 0, π/2 in the interval [0, 2pi).
Step-by-step explanation:
Use the auxiliary angle method:
R sin(x + a) = Rsin x cos a + Rcos x sin a = 1
sin x + cos x = 1
Comparing coefficients:
R cos a = 1 and R sin a = 1, so
tan a = R sin a / R cos a = 1
So a = π/4 radians.
Also R^2(sin^2 a + cos^2 a) = 1^2 + 1^2 = 2
Therefore R = √2.
So √2 sin (x +π/4 = 1
sin x + π/4 = 1/√2
x + π/4 = π/4
x = 0 radians
Also
x = 0 + π/2 = π/2.
Answer:
y=2x-2
y=3x+1
Step-by-step explanation:
To solve this I will be using the point slope formula
It is as follows
y-y₁=m(x-x₁)
We can choose any m value so I will be choosing m=2
(x₁,y₁) will be (-3,-8) respectively because all we want is for the line to pass through that point
so we have
y-(-8)=2(x-(-3)
We can simplify this to
y+8=2(x+3)
y+8=2x+6
y=2x-2
We then repeat this process but choose a new m (the m value doesn't really matter as long as it's not 0)
I will choose 3
so we have
y-(-8)=3(x-(-3))
Which gives u
y+8=3(x+3)
y+8=3x+9
y=3x+1
The answer would be .67 or .66666... since it’s infinite; or 2/3 in fraction form
