Answer:

25 months

Step-by-step explanation:

Plan A : $70 per month

Plan B : $50 per month + $500 as a one time cost.

So for A $70 a month would take 8 months to be at least $500

And for B it in those 8 months it would cost you $900

But we have to keep going up until they are equal

25*70 = 1750

(25*50) = 1250+500=1750

So yes 25 months is correct

(5x^5) - (80x^3)<br> factoring

elena55 [62]

Answer:

Factoring the term $(5x^5) - (80x^3)$ we get $\mathbf{5x^3(x-4)(x+4)}$

Step-by-step explanation:

We need to factor the term $(5x^5) - (80x^3)$

First we can see that $5x^3$ is common in both terms

So, taking $5x^3$ common:

$(5x^5) - (80x^3)\\=5x^3(x^2-16)$

We can write $x^2-16$ as $(x)^2-(4)^2$

$=5x^3((x)^2-(4)^2)$

Now we can solve $(x)^2-(4)^2$ using the formula: $a^2-b^2=(a+b)(a-b)$

We can write:

$=5x^3((x)^2-(4)^2)\\=5x^3(x-4)(x+4)$

So, factoring the term $(5x^5) - (80x^3)$ we get $\mathbf{5x^3(x-4)(x+4)}$

Robert traveled 80 miles per hour. What equation shows the relationship between distance traveled (d), speed (s), and time taken

Evgen [1.6K]

Answer:

$80 = \frac{d}{t}$
d=80t
$t = \frac{d}{80}$

Step-by-step explanation:

The relationship between distance traveled (d), speed (s), and time taken (t) can be represented the following expressions:

$s = \frac{d}{t}$
d = st
$t = \frac{d}{s}$

Using any of these expressions you can show the relationship. Substitute s = 80 for the speed.

$80 = \frac{d}{t}$
d=80t
$t = \frac{d}{80}$
