Part B: It would be 8x+24. You get 4x+12 and double(times 2) it, it would be 8x+24.
Part C: Yes, because the relationship between the ratio would always be proportional.
The end behavior of functions with exponents is quite simple when you realized that as x approaches infinity that the function will act as if the highest exponent term is the only one which exists...
In this case 3x^8 is the highest order term, so y approaches +oo as x approaches +oo or -oo. Or in other words y increases without bound as x approaches ±oo
Answer:
you will get a decimal answer which is 94.10526316
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
since y is inversely proportional to x the equation relating them is
y = 
← k is the constant of proportionality
to find k use the given condition when y = 7, x = 9
k = yx = 7 × 9 = 63
y = 
← is the equation connecting them
when x = 21, then
y = 
= 3
Answer:
7/10 ≥ j - 3/8
Switch sides,
j - 3/8 ≤ 7/10
Add 3/8 to both sides,
j - 3/8 + 3/8 ≤ 7/10 + 3/8
Simplify,
j ≤ 43/40
