Solve the system of equations given below.
lbvjy [14]

Answer:

B

Step-by-step explanation:

-5x = y - 5 (1)

-2y = -x - 21 (2)

Change x to the left hand side of equation (2)

x = 2y - 21 (3)

Multiply (1) by 2 times:

-10x = 2y - 10 (4)

Use (4) - (3)

-10x = 2y - 10

- x = 2y - 21

-11x = -10 + 21

-11 x = 11

x = -1

Apply x = -1 in (1)

-5*(-1) = y - 5

5 = y-5

y = 5+5

y = 10

So x = -1

y = 10

Hope this help you :3

saveliy_v [14]

Answer:

The function is

f(x)=0.5x^3-3x^2+5.5x-2

The graph is attached.

Step-by-step explanation:

We have a function g(x) and we need to graph a new function that is function of g(x).

The final function is

f(x)=0.5\cdot g(x-2)+1

We start by calculating g(x-2):

g(x-2)=(x-2)^3-(x-2)\\\\g(x-2)=(x^3-6x^2+12x-8)-(x-2)\\\\g(x-2)=x^3-6x^2+11x-6

Then, we can calculate f(x) as:

f(x)=0.5\cdot g(x-2)+1\\\\g(x-2)=x^3-6x^2+11x-6\\\\\\f(x)=0.5(x^3-6x^2+11x-6)+1\\\\f(x)=0.5x^3-3x^2+5.5x-3+1\\\\\\f(x)=0.5x^3-3x^2+5.5x-2
