How do i write a polynomial functions that has roots 3 and 7

Step-by-step explanation:

x^2 - (a+b)x + ab = 0

here, a = 3 and b = 7

hence,

x^2 - (10x) + 21 = 0

lastly , the quadratic equation is

x^2 - 10x + 21 = 0

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

yes because they have the same amount of green and blur marbles.
