4. Solve for x and y

Mathematics
1 answer:
arlik [135]2 years ago
3 0

Answer:

Step-by-step explanation:

Intersecting lines make equal opposite angles

2x + y = 50 - y

     2x = 50 - 2y

       x = 25 - y

A straight line represents 180°

4x + 6y + 2x + y + 2x + 3y = 180

                            8x + 10y = 180

                  8(25 - y) + 10y = 180

                  200 - 8y + 10y = 180

                                     2y = -20

                                       y = -10

       x = 25 - (-10)

       x = 35

Use the relationship between the angles in the figure to answer the question.
Anuta_ua [19.1K]

Answer:

37+x+53 = 180

x=90

Step-by-step explanation:

To find x, we need to use the fact that a straight line equals 180 degrees.

37+x+53 = 180

Combining like terms

90+x = 180

Subtract 90 from each side

90-90+x = 180-90

x = 90

Find a degree 3 polynomial with real coefficients having zeros 2 and 2 − 2 i and a lead coefficient of 1. Write P in expanded fo
Zanzabum

Answer:

The polynomial with real coefficients having zeros 2 and 2 - 2i is

x³ - 6x² + 16x - 16 = 0

Step-by-step explanation:

Given that a polynomial has zeros at 2 and 2 - 2i, we want to write this polynomial.

We have

x - 2 = 0

x - (2 - 2i) = 0

=> x - 2 + 2i = 0

Since the polynomial has real coefficients, and 2 - 2i is a zero of the polynomial, the conjugate of 2 - 2i, which is 2 + 2i is also a polynomial.

x - (2 + 2i) = 0

=> x - 2 - 2i = 0

Now,

P(x) = (x - 2)(x - 2 + 2i)(x - 2 - 2i) = 0

= (x - 2)((x - 2)² - (2i)²) = 0

= (x - 2)(x² - 4x + 8) = 0

= x³ - 4x² + 8x - 2x² + 8x - 16 = 0

= x³ - 6x² + 16x - 16 = 0

This is the polynomial required.
