Answer:
<u>The numbers are -61 and -68</u>
Step-by-step explanation:
x = Smaller number
y = Larger number
x + y = - 129
y = x + 7
*********************************
x = - 129 - y
*********************************
Substituting x and solving for x and y, we have:
y = -129 - y + 7
2y = - 129 + 7
2y = -122
y = -122/2
y = -61 ⇒ x = -68
<u>The numbers are -61 and -68</u>
Given y = 7/x² + 10
Let,
y = f(x)
f(x) = 7/x² + 10
And,
g(x) = x²
Hence, f(g(x))
Reason is;
You have to rewrite f(x) so that it can fit in g(x) into the equation
f(x) = 7/g(x) + 10
