I'll presume the slash is the fraction bar and the questioner is asking about
That always equals 4 except when 
So the restriction is
Answer: a ≠ -3
Question:
Convert the angle θ=260° to radians.
Express your answer exactly.
θ = ___ radians
Answer:
260° = 13π/9 or 4.54 rad
Step-by-step explanation:
Given
θ=260°
Required
Convert from degree to radians
To convert an angle in degrees to radians, we simply follow the steps below.
1° = 1 * π/180 rad
Replace the 1° with x
So,
x° = x * π/180 rad.
Now, we assume that x = 260
This means that we substitute 260 for x. This gives
260° = 260 * π/180
260° = 260π/180
Divide numerator and denominator by 20
260° = 13π/9
We can leave the answer in this form or solve further.
Take π as 22/7. This gives
260° = 13/9 * 22/7
260° = 286/63
260° = 4.5396825397
260° = 4.54 rad (Approximated)
The answer is y=1/2x + 7.
The plot is (-2,2), so what it actually is, is (x,y) so you always have the same slope when lines are parallel. So you just need to solve for the y-intercept. so you substitute -2 in for x and you get the y-intercept! Hope this helps!
