Simplify -3p^3+5p+(-2p^2) +(-4) -12p +5 -(-8p^3)

GenaCL600 [577]

Simplify the following:

8 p^3 - 3 p^3 - 2 p^2 + 5 p - 12 p - 4 + 5

Grouping like terms, 8 p^3 - 3 p^3 - 2 p^2 + 5 p - 12 p - 4 + 5 = (-3 p^3 + 8 p^3) - 2 p^2 + (5 p - 12 p) + (-4 + 5):

(-3 p^3 + 8 p^3) - 2 p^2 + (5 p - 12 p) + (-4 + 5)

8 p^3 - 3 p^3 = 5 p^3:

5 p^3 - 2 p^2 + (5 p - 12 p) + (-4 + 5)

5 p - 12 p = -7 p:

5 p^3 - 2 p^2 + -7 p + (-4 + 5)

5 - 4 = 1:

Answer: 5 p^3 - 2 p^2 - 7 p + 1

F(x)=5 g(x)=sqrt x+2 find: (f-g)(x) (f • g(x) (f/g)(x) (f o g)(x)

Sergeeva-Olga [200]

f(x) = 5

g(x) = $\sqrt{x + 2}$

(f-g)(x) = 5 - $\sqrt{x + 2}$

(f * g)(x) = 5 $(\sqrt{x + 2})$ = $5\sqrt{x + 2}$

(f/g)(x) = $\frac{5}{\sqrt{x + 2}}$ = $\frac{5\sqrt{x + 2}}{{x + 2}}$

f(g(x)) = 5

mars1129 [50]

Answer:

y= 20

Step-by-step explanation:

y=2*5x

Let x =2

y = 2*5 (2)

There are 10 blue marbles, 4 black marbles, 5 white marbles, and 6 red marbles in a box. If two marbles are drawn at random with

Nikitich [7]

Answer:

7/20

Step-by-step explanation:

10 blue marbles, 4 black marbles, 5 white marbles, and 6 red marbles = 25 marbles

25-10 = 15

There are 15 not blue marbles

P( not blue ) = not blue marbles / total = 15/25 = 3/5

keep the not blue marble

25-1 = 24 marbles left

15-1 = 14 not blue marbles

P( not blue ) = not blue marbles / total = 14/24 = 7/12

P( not blue, keep, not blue) = 3/5 * 7/12 = 21/60 = 7/20

MaRussiya [10]

Answer:

In the year 2010, the population of the city was 175,000

Step-by-step explanation:

If we rewrote this as a linear expression in standard form (it is linear, btw), it would look like this:

$P(t)=\frac{11}{2}t+175$

The rate of change, the slope of this line, is 11/2. If the year 2010 is our time zero (in other words, we start the clock at that year), then 0 time has gone by in the year 2010. In the year 2011, t = 1 (one year goes by from 2010 to 2011); in the year 2012, t = 2 (two years have gone by from 2010 to 2012), etc. If we plug in a 0 for t we get that y = 175,000. That is our y-intercept, which also serves to give us the starting amount of something time-related when NO time has gone by.
