Bring the fraction a/a−4 to a denominator of 16−a^2
really do appreciate this thx
1 answer:
Answer:
-a(a+4)/(16 - a²)
Step-by-step explanation:
a/(a - 4) Multiply by (a + 4)/(a + 4)
= a(a + 4)/[(a – 4)(a + 4)] Multiply the denominatorator terms
= a(a + 4)/(a² - 16) Multiply by -1/(-1)
= -a(a+4)/(-a² + 16) Reorder terms in denominator
= -a(a+4)/(16 - a²)

so 15
To write this function in function notation all you would need to do is rearrange the equation for y.
3x + 2y = 12
3x - 3x + 2y = 12 - 3x
2y = 12 - 3x
2y/2 = 12/2 - 3x/2
Y = 6 - 3/2 X or
Y = -3/2 X + 6.
The answer is B because -3.62 is less than -3.5 and greater than -3.8.
Answer:
Literally use any answer which has a higher slope so . . .
y = 10x + 1
y = 1000000000000000000x + 1
and so on.
