a/5 - b/2 = 10...(1)

2a-5b/10 = 10

2a-5b=10×10

2a-5b=100...(2)

a-b=29...(3)

2a-2b=58...(4)

subtract (4) from (2)

2a-5b=100

2a-4b=58

-b = 42

b = -42

2a-2b=58

2a-2(-42)=58

2a+84=58

2a=-26

a= -13

Please help i’m blanking lol
tangare [24]

Answer:

The answer is the graph D

Step-by-step explanation:

The inequation states that:

abs(x) >3.

By definition, the absolute value | x | is the distance of x from zero. In this case: | x | > 3 The solution is going to be all the points that are greater than three units away from zero.

For that reason the solution is -3>x>3. That is to say, all values greater than 3 or less than -3 are solutions.

Answer:

Length: 12

Width: 2\sqrt{10\\}

Area: 24\sqrt{10\\}

Step-by-step explanation:

We first find the points of C and D to find the length.

C: (-4,-5)

D: (2,-3)

The distance is 2\sqrt{10\\.

Now for the height.

A: (2,9)

D: (2,-3)

The distance is 12.

Area: 2\sqrt{10\\×12 = 24\sqrt{10\\}
