Answer:

-2x^2-3x-4

Step-by-step explanation:

We have to simplify the expression (x^2-8x+5)+(-3x^2+5x-9)

Distribute the positive sign over the parenthesis

x^2-8x+5-3x^2+5x-9

Combine the like terms

-2x^2-3x-4

Therefore, the expression after simplification is -2x^2-3x-4

Second option is correct.

Answer: y = 5x

Step-by-step explanation:

(check to make sure it matches the graph)

Find x and y so that the quadrilateral is a parallelogram.
sergiy2304 [10]

Answer:

Result:

  • The value of x = 12
  • The value of y = 21

Step-by-step explanation:

Given

The parallelogram DEFG

DE = 6x-12

FG = 2x+36

EF = 4y

DG = 6y-42

We know that the opposite sides of a parallelogram are equal.  

As DE and FG are opposite sides, so

DE = FG

substituting DE = 6x-12 and FG = 2x+36 in the equation

6x-12 = 2x+36

6x-2x = 36+12

simplifying

4x = 48

dividing both sides by 4

4x/4 = 48/4

x = 12

Therefore,

The value of x = 12

Also, EF and DG are opposite sides, so

EF = DG

substituting EF = 4y and DG = 6y-42 in the equation

4y = 6y-42

switching sides

6y-42 = 4y

6y-4y = 42

2y = 42

dividing both sides by 2

2y/2 = 42/2

y = 21

Therefore,

The value of y = 21

Result:

  • The value of x = 12
  • The value of y = 21
