Hey there! :)

Answer:

First option: As x⇒ ∞ f(x) ⇒ -∞.  As x⇒ -∞ f(x) ⇒ ∞.

Step-by-step explanation:

Rearrange the equation:

f(x) = -x³ - 2x² + 1

This is a negative cubic function. The function decreases over the interval

(-∞, ∞). Therefore:

As x⇒ ∞ f(x) ⇒ -∞.

As x⇒ -∞ f(x) ⇒ ∞.

This is the first option.

True [87]

Answer:

I would say About $175

Step-by-step explanation:

This is all based on the picture, the simple interest is $500 after 35 years, and the compound interest is almost at $700, so if it is not $200 yet, it has to be $175.

6=x+2/3 Please help me
vekshin1

Answer: x=5.33333333333

Step-by-step explanation:

6=x+2/3

We simplify the equation to the form, which is simple to understand  

6=x+2/3

Simplifying:

6=x + 0.666666666667

We move all terms containing x to the left and all other terms to the right.  

-1x=0.666666666667-6

We simplify left and right side of the equation.  

-1x=-5.33333333333

We divide both sides of the equation by -01 to get x.  

x=5.33333333333

Nicole drove 156 miles to her gradmothers house last week for family reunion.Her sister drove 5/4 of the distance to get to the

156 more miles.

My Work:
The Sister drove 5/4 of 156 miles. <u />The <u />"of" stands for multiplication. 5/4 * 156/1
<u />After we solve the equation, we learn that the Sister drove 195 miles, which would mean that the sister probably drove too far, leaving Nicole to drive back for them.
Because Nicole is driving the rest of the 195-156 miles, if we use the triangle sum method from elementary school, we can flip the answer to 195-156 with 156 and know that the Sister drove 156 more miles than Nicole without having to know how far Nicole drove.
