Answer:

$3y^{2}+2y-11$

Step-by-step explanation:

we have

$(-y^{2}-4y-8)-(-4y^{2}-6y+3)$

Eliminate the parenthesis

$-y^{2}-4y-8+4y^{2}+6y-3$

Group terms that contain the same variable

$-y^{2}+4y^{2}-4y+6y-8-3$

Combine like terms

$3y^{2}+2y-11$

Glven: F(x) = 2x - 1; G(X) = 3x + 2; H(x) = x2<br> Find F/G/H(2)<br> 121<br> 27<br> 71

Answer:

3/32

Step-by-step explanation:

One approach to doing this probelm is to evaluate all three functions F, G and H at x = 2:

F(2) = 2(2) - 1 = 3

G(2) = 3(2) + 2 = 8

H(2) = (2)^2 = 4

3/8

Then (F/G)(2) = (3/8), and (F/G/H) = -------- = 3/32

Bruce is going to call one person from his contacts at random. He has 25 total contacts. 20 of those contacts are from his neigh

Naya [18.7K]

<h3>P(call a person not from his neighborhood) = $(\frac{1}{5} )$ </h3>

Step-by-step explanation:

Here, the total number of contacts in the list if Bruce = 25 contacts

The total number of neighbors in the contact = 20 people

Now, let E: Event of calling a person from his neighborhood

So, P(E) = $\frac{\textrm{Total Favorable Outcomes}}{\textrm{Total Outcomes}} = \frac{20}{25} = (\frac{4}{5})$

So, the probability of calling a person from his neighborhood is $(\frac{4}{5} )$

⇒P(E) = $(\frac{4}{5} )$

Now,as we know: P(E) + P(not E) = 1

So, the probability of NOT calling a person from neighborhood

= 1 - probability of calling a person from his neighborhood

$= 1 - (\frac{4}{5}) = \frac{5-4}{5} = (\frac{1}{5})$

⇒P( not E) = $(\frac{1}{5} )$

Hence, P(call a person not from his neighborhood) = $(\frac{1}{5} )$
