Equivalent expressions are expressions of equal values

The simplified expression of (3 - 4i) + (7 - 6i) is 10- 10i

The expression is given as:

(3 - 4i) + (7 - 6i)

Remove brackets in the above expression

3 - 4i + 7 - 6i

Rewrite the expression by collecting the like terms

3 + 7- 4i  - 6i

Next, evaluate the like terms

10- 10i

Hence, the simplified expression of (3 - 4i) + (7 - 6i) is 10- 10i

Parabolas y=−2x^2 and y=2x^2 +k intersect at points A and B that are in the third and the fourth quadrants respectively. Find k
OverLord2011 [107]

Answer:

-25  

Step-by-step explanation:

(1)   y = -2x²

(2) y =   2x² + k     Subtract (1) from (2)

    0 =  4x² + k      Subtract 4x² from each side

    k = -4x²

The parabolas are <em>symmetrical about the y-axis.</em>

Segment AB = 5, so x = +2.5 and x = +2.5.

k = -4(±2.5)² = -4 × 6.25 = -25
