Answer:
Below in bold.
Step-by-step explanation:
x^2 - y^2 = 11
2x^2 + y^2 = 97
From the first equation:
y^2 = x^2 - 11
Substituting in the second equation:
2x^2 + x^2 - 11 = 97
3x^2 = 108
x^2 = 36
x = 6, -6.
Substituting for x in the first equation:
(6)^2 - y^2 = 11
y^2 = 36 - 11 = 25
y = 5, -5.
the answer should be A because the sea level has rised
y = -2|x +1|
→ |x + 1| = -y/2
→ x+1 = y/2
and
x + 1 = -y/2
→ x + 1 belongs to R
→ x belongs to R
Domain = R
Range = y = -2(R)
→( -∞ , 0)
can you pop out all the boxes I need to see what the numbers are to get a further understanding
-4/3
mtan × mline = -1
mtan× 3/4 = -1
mtan =-4/3
