Mathematics
1 answer:
Reil [10]3 years ago
4 0

Answer:

4) J

5) D

Step-by-step explanation:

4) 416 = 2x² - 6x

2x² - 6x - 416 = 0

x² - 3x - 208 = 0

x² - 16x + 13x - 208 = 0

x(x - 16) + 13(x - 16) = 0

(x - 16)(x + 13) = 0

x = 16, -13(not possible)

So 16 rows

5) y = a(x - h)² + k

y = a(x - 3)² - 7

When x = 1, y = -10

-10 = a (1 - 3)² - 7

-10 = 4a - 7

4a = -3

a = -¾

y = -¾(x - 3)² - 7

Answer:

  x= 10, corresponding

__

Corresponding angles are congruent, so we have ...
