The answer would be A. -0.86 because if you plug in -0.86 for r then add -0.86 and 0.27 then you would get the correct answer which would be -0.58. :)
Answer:
α = 20.5
β = 69.5
c = 90
Step-by-step explanation:
we have to make 2 equations one for the relationship between the angles and another for the sum of all the angles
β and α are the acute angles
β = 3α + 8
α + β + 90 = 180
we replace in the second equation the value of β by (3α + 8)
α + β + 90 = 180
α + (3α + 8) + 90 = 180
a + 3a = 180 - 90 - 8
4a = 82
a = 82/4
a = 20.5
now we replace the value of b in the other equation
β = 3α + 8
β = 3 * 20.5 + 8
β = 69.5
You will need to show all the answers that are at 25 or less.
Please see the attached paper for the inequality and the graph of the possible solutions.
A filled in circle means to include that value.
8xy^2 - 3xy^2 = 5xy^2
7xy^2 - 2xy^2 = 5xy^2
Answer A
They have the same x-intercept but different end behavior as x approaches ∞ :)
