Answer:

-10 is the correct answer to the given question .

Step-by-step explanation:

Missing information:

Following question is incomplete there is no information about the vertices and the rules .Following are the complete question that is mention below

Triangle PQR has vertices P(-2, 6), \ Q(-8, 4), and\  R(1, -2). It is translated according to the rule    (x, y)\ -> \  (x\  - \ 2, y\  - 16). What is the y-value of P'?

Now coming to the solution as already mention in the question

The translated rule is (x, y)\  -> (x - 2, \ y -16).

Now calculated the vertices P value according to the rule of translated

P(-2, 6)\\Now \  apply \ the\ translated\ rule \ in\  P\ vertices\\P(-2, 6)->P1(-2-2,\ 6-16)\\P1->(-4,-10)

So -10 is the value of y in P vertices .

8a - 4b = 20<br>5a - 8b = 62<br><br>What are the values of a and b?​
erastovalidia [21]

Answer:

a=2 , b= (-1)

Step-by-step explanation:

8a-4b=20/×(-2)

5a-8b=62

-16a+8b= -40

5a-8b=62

now -8+8=0 right? so the only parameter that we have is a.

-16a+5a= -40+62

11a = 22/(÷11)

a=2

in order to find b, we will replace a with its value in one of the original equations (it doesn't matter which one you will choose).For instance, I chose the first one.

8×2-4b=20

-4b=20-16

-4b=4/÷(-4)

b= -1

3. Multiply the polynomials (a^2 + 3a – 4) and (2a^2 – a + 5). Simplify the answer. Show your work.
Elza [17]

Answer:

2a^4+5a^3-6a^2+19a-20

Step-by-step explanation:

(a^2+3a-4)(2a^2-a+5)

2a^4-a^3+5a^2+6a^3-3a^2+15a-8a^2+4a-20

2a^4-a^3+6a^3+5a^2-3a^2-8a^2+15a+4a-20

2a^4+5a^3+2a^2-8a^2+19a-20

2a^4+5a^3-6a^2+19a-20

Based on the given information, what is the measure of the missing length, c?
salantis [7]

Answer:

c=5\ units

Step-by-step explanation:

we know that

In the right triangle ABC of the figure

Applying the Pythagoras Theorem

AC^{2}=AB^{2}+BC^{2}

substitute the given values

13^{2}=c^{2}+12^{2}

Solve for c

169=c^{2}+144

c^{2}=169-144

c^{2}=25

c=5\ units
