Answer:

(1,6) & (7,0)

Step-by-step explanation:

y = -x + 7

y = -0.5(x - 3)² + 8

To solve the system, solve these two equations simultaneously

-x + 7 = -0.5(x - 3)² + 8

-x + 7 = -0.5(x² - 6x + 9) + 8

-x + 7 = -0.5x² + 3x - 4.5 + 8

0.5x² - 4x + 3.5 = 0

x² - 8x + 7 = 0

x² - 7x - x + 7 = 0

x(x - 7) - (x - 7) = 0

(x - 1)(x - 7) = 0

x = 1, 7

y = -1 + 7 = 6

y = -7 + 7 = 0

(1,6) (7,0)

Since the system has two distinct solutions, the line and the curve meet at two distinct poibts9: (1,6) & (7,0)

Slope= -3; (1, 2) is on the line
wolverine [178]

Step-by-step explanation:

By 2 point form

y-y1= m(x-x1)

y-2 = -3(x-1)

y-2=-3x+3

3x+y=5... this is the required line

A polynomial has one root that equals 4+17i name one other root of this polynomial
Lapatulllka [165]
In any polynomial when you have an imaginary root, there is always another imaginary root that is the conjugate of the first one:
1st root:  4 + 17i
2nd root: 4 - 17i  (the conjugate of the 1st one)
