Answer: Choice D

y goes to negative infinity for both cases of x going to infinity or negative infinity.

==========================

Explanation:

The degree of this function is 4, as it is the largest exponent. The even number degree tells us that the end behavior is that either

case A: the endpoints rise together

or

case B: the endpoints fall together

In short, the endpoints are more or less mirror copies going in the same direction.

In this case, both endpoints fall together as the leading coefficient (-3) is negative. As x heads off to infinity, y will go to negative infinity. As x heads off to negative infinity, y will also go to negative infinity. Regardless of which direction x goes, y will go downhill.

note: your book may refer to this as "fall to the left and fall to the right".

Please solve this problem.
just olya [345]

x=number of oranges.

y=number of bananas.

$5

we can suggest this system of equations:

x+y=12

0.5x+0.25y=5

We can solve this system of equations by substitution method.

x=12-y

0.5(12-y)+0.25y=5

6-0.5y+0.25y=5

-0.25y=5-6

-0.25y=-1

y=-1 /- 0.25=4

x=12-y

x=12-4=8

Does anyone know how to solve this?
masya89 [10]

Answer:

b = -125/9

Step-by-step explanation:

1 + log5 ( -9b) = 4

Subtract 1 from each side

1 -1+ log5 ( -9b) = 4-1

log5 ( -9b) = 3

Raise each side to the base 5

5^  log5 ( -9b) = 5^3

This will cancel the log5

-9b = 125

Divide each side by 9

-9b/-9 = 125/-9

b = -125/9

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb
Aleks [24]

The equation would be : 10y + 3x = 50

Hope this helps :)
