#1

  • x-4y≤-12
  • -4y≤-x-12
  • 4y≥x+12
  • y≥1/4x+3

Put (0,0)

  • 0≥0+3 is false

Shading will be away from origin.

y inetercept

  • y=3(when x=0)

Check the direction of line by taking 4 and -4

  • y=4/4+3=y=4
  • y=-4/4+3=-1+3=2

The graph should bend down on left side while rise up in right side

Option A

#2

  • 5x-4y>4
  • -4y>-5x+4
  • 4y<5x-4
  • y<5/4x-1

Putting origin in it

  • 0>-1

Shading away from origin

And

  • x+y<2
  • y<2-x

Putting origin

  • 0<2

Shading towards origin

  • Option B as shading should be downwards here

Answer:

BELOW

Step-by-step explanation:

DO I HEAR 100 POINTS? Yes.

For the first image, that answer is A.

For the second image, I'm a bit confused on which problems you want me to do, so I'll do number 10, 11, and 14.

10) Yeah, you're correct, it is J.

11) (1,-6), (-2,-5), (8,2) (4,0) and I can't see the last point so..

14)  Can't see the question :(

19) Solve the inequality. 7x − 9 &gt; 2x + 6 A) x &gt; 3 B) x &gt; 3 5 C) x &gt; −3 D) x &gt; − 3 5
Marianna [84]

Answer:

B

Step-by-step explanation:

Given

7x - 9 > 2x + 6 ( subtract 2x from both sides )

5x - 9 > 6 ( add 9 to both sides )

5x > 15 ( divide both sides by 3 )

x > 3 → B

Find the LCD of the given rational equation: -3/x+2 + 5x/x-1 = x+2/x^2-3x+2
Natali [406]
Answer:

(x - 1)( x - 2) (x + 2) = x³ -x² -4x + 4.

Explanation:

1) Given equation:

    3             5x            x + 2
- ------- +  -------- =  ---------------
 x + 2        x - 1       x² - 3x + 2

2) So, the denominators are x + 2, x - 1, and x² - 3x + 2

3) The LCD is the product of the common and non common factors raised to the greatest power.

4) x + 2, and x - 1 are already prime factors

5) Factor x² - 3x + 2

x² - 3x + 2 = (x - 2)(x - 1)

6) Then, the factors are x + 2, x - 1, and x - 2, and the LCD is the product of them:
(x - 1)( x - 2) (x + 2)

7) If you expand the products (distributive property) you get:
x³ -x² -4x + 4.
