Answer:

(5,1)

Step-by-step explanation:

4x + 7•(x /4-1/4) = -13

-9x/4 = -45/4

-9x = -45

Solve equation for the variable x

9x = 45

x = 5

By now we know this much :

x = 5

y = x/4-1/4

Use the x value to solve for y

y = (/4)(5)-1/4 = 1

Vilka [71]

Answer:

$8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6$

Step-by-step explanation:

We want to simplify;

$(8r^6s^3-9r^5s^4+3r^4s^5)-(2r^4s^5-5r^3s^6-4r^5s^4)$

We expand the bracket to obtain;

$8r^6s^3-9r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6+4r^5s^4$

We now group the like terms to obtain;

$8r^6s^3-9r^5s^4+4r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6$

We now simplify to get;

$8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6$

The correct answer is C
