Consider the system of inequalities.

Ugo [173]

Answer:

The point is (-1,5) and (0,0) also satisfies the given inequalities

The solution of the given inequalities

(x, y) = (4 , -2 )

Step-by-step explanation:

Step(i):-

Given system of equations are

3x + 2y < 8

-5x - 9y > -2

The solution of the given equations are

3x + 2y = 8 multiply '5'

-5x - 9y = -2 multiply '3'

15 x + 10 y = 40 ...(i)

-15x - 27 y = -6.....(ii)

Adding (i) and (ii) , we get

- 17 y = 34

y = -2

Substitute y = -2 in equation 3x + 2y =8

3x - 4 =8

3x = 12

x =4

The solution of the given system of inequalities

(x, y) = (4 , -2 )

Step(ii):-

3x + 2y < 8

-5x - 9y > -2

The point is (-1,5)

-3 + 10 < 8

7 < 8

5 - 45 > -2

-40 > -2

The point (0,0) also satisfies the given inequalities

Final answer :-

The point is (-1,5) and (0,0) also satisfies the given inequalities

For the function F defined by F(x) = x2 – 2x + 4, find F(b+3).

Ivanshal [37]

Answer:

$\displaystyle F(b + 3) = b^2 + 4b + 7$

Step-by-step explanation:

We are given the function:

$\displaystlye F(x) = x^2 - 2x + 4$

And we want to find F(b + 3).

We can substitute:

$\displaystyle F(b + 3) = (b + 3)^2 - 2(b+3) + 4$

Expand:

$\displaystyle = (b^2 + 6b + 9) + (-2b -6) + 4$

Rearrange:

$\displaystyle = (b^2) + (6b-2b) + (9 - 6 + 4)$

Combine like terms. Hence:

$\displaystyle = b^2 +4b + 7$

In conclusion:

$\displaystyle F(b + 3) = b^2 + 4b + 7$
