Hello,
If center is (0,0)
x²/a²+y²/b²=1 for a half horizontal axis of a, and a half vertical axis of b
Here
a=2 ==> a²=4
b=8 ==> b²=64
Answer:
The answer to this question is A
Answer:
First one: function and linear
Second one: function and non-linear
Third one: not a function and linear
Step-by-step explanation:
• The first one is set in the linear function formula y=mx+b, so it is a linear function.
• The second one is a non-linear because functions with exponents have different shapes and can intersect more than once unline linear functions.
• The third one isn't a function but it is linear because it isn't set equal to a variable and it would become a linear if you simply it to isolate a variable.
I hope this helps!!!
(w³+7)/w=(9w²+7)/9
(w³+7)9=(9w²+7)x
9w³+63=9w³+7x
63=7x
x=9
