Use substitution
From second equation:-
x = 13 - 5y, Substitute for x in the first eqaution:
(13 - 5y)^2 + y^2 = 13
169 -130y + 25y^2 + y^2 - 13 = 0
26y^2 - 130y + 156 = 0
26(y^2 - 5y + 6) = 0
26(y - 3)(y - 2) = 0
y = 2 , y = 3
From the second equation when y = 2, x = 13 - 5(2) = 3
and when y = 3, x = 13 - 5(3) = -2
So the solution is [3, 2} and {-2, 3}
Answer:
The measure of angle YZX is 39.4°.
Step-by-step explanation:
Given information: ΔXYZ is a right angled triangle, ∠Y=90°, XY=12.4 cm, YZ=15.1 cm.
In a right angled triangle,
In triangle XYZ,
Taking tan⁻¹ on both sides.
Therefore the measure of angle YZX is 39.4°.
A year is 12 months, therefore inserting it into the equation in place of the m, it is 12.25(12) +29.99, which equals 176.99 being less than 180. therefore yes you can buy a 1 year membership
