Hey there! :)
Answer:
Choice 4: π/4, 3π4, 7π/4
Step-by-step explanation:
For the values of θ to have the same reference angles, the denominators of the radians must be the same. Therefore:
Choice 1: π/6, π/3, 5π/6 - incorrect. π/3 will have a different reference angle as it has a denominator of 3.
Choice 2: π/3, 5π/6, 4π/3 - incorrect. 5π/6 will have a different reference angle as it has a denominator of 6.
Choice 3: π/2, 5π/4, 7π/4 - incorrect. π/2 will have a different reference angle.
Choice 4: π/4, 3π4, 7π/4 - correct. All of these radians contain the same denominator, and will each have the same reference angles of π/4.
Answer:
if x is by itself it's 1
Step-by-step explanation:
If a question as x=10 x is equal to the number
If the bold numbers and variables are 2x + 5, then those would be B. addend, or the numbers that are added. Minuend is the number from which you subtract.
And since there is no dividing here, C or D are incorrect.
Answer:
x = 12
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
4x = 48 ( divide both sides by 4 )
x = 12
Answer:
Slope-intercept form: y=-3x-2
Point-slope form: y+5=-3(x-1)
Step-by-step explanation:
Slope-intercept form is y=mx+b
Point-slope form is y-y1=m(x-x1)
The slope is (7-(-5))/(-3-1)=12/-4=-3
Now we solve for b, aka. the y-intercept:
-5=-3(1)+b
-5=-3+b
-2=b
So the equation in slope intercept form is y=-3x-2
As for point-slope form, it's y+5=-3(x-1)
