Determine the two ordered pair solutions of the equation y = 2x2 + 3x , given (0, ), and (-2, ).
Rudiy27

Answer:

We conclude that the two ordered pairs (0, 0) and (-2, 2) are the solutions of the equation y = 2x² + 3x.

Step-by-step explanation:

Given the expression

y = 2x² + 3x

Substituting x = 0

y = 2(0)² + 3(0)

y = 0+0

y = 0

  • so when x = 0, y = 0

Thus, the ordered pair is: (0, 0)

Now, substituting x = -2

y = 2x² + 3x

y = 2(-2)² + 3(-2)

y = 8 - 6

y = 2

  • so when x = -2, y = 2

Thus, the ordered pair is: (-2, 2)

Therefore, we conclude that the two ordered pairs (0, 0) and (-2, 2) are the solutions of the equation y = 2x² + 3x.

The lengths of the sides of a triangle are in the extended ratio 8 : 9 : 10. The perimeter of the triangle is 108cm. What are th
belka [17]

Answer:

32, 36, 40

Step-by-step explanation:

8x + 9x + 10x = 108

27x = 108

x = 4

4 × 8 = 32 - 1st side

4 × 9 = 36 - 2nd side

4 × 10 = 40 - 3rd side

Find the equation of the line containing the point (3, 3) and parallel to the line
DIA [1.3K]

Answer:

y = 2x - 3

Step-by-step explanation:

Parallel lines have the same slope

only the constant changes

y = 2x + b

To find "b"

Plug in point (3, 3)

3 = 2(3) + b

3 = 6 + b

Subtract 6 from both sides

-3 = b

The equation for the parallel line is

y = 2x - 3
