Insert y in the second equation and solve for x:
4x+(x^2-8)=-8
4x+x^2-8=-8
4x+x^2=0
x^2+4x=0
x = -4
Now you insers this x-value in the first or second equation (i use the first):
y=(-4)^2-8=16-8=8
Therefore the conclusion must be x=-4 and y=8
Answer:
30 degrees
Step-by-step explanation:
Answer:
x = 8.8
Step-by-step explanation:
take 20 degree as reference angle .the,
hypotenuse = OQ = x (hypotenuse is always opposite of 90 degree)
perpendicular(opposite) = PQ 3 (opposite of reference angle is perpendicular or also called as opposite)
base(adjacent) = OP (side which lies on the same line where 90 degree and reference angle)
using sin rule
sin 20 = opposite / hypotenuse
0.34 = 3 / x
x = 3/0.34
x = 8.82
x = 8.8
