Phil is considering the number of combinations that can be made with his hats and sunglasses. He has and he can make y combinations. He has 2 more pairs of sunglasses than hats. The number of combinations he can make is 5 more than 6 times the number of hats that he has. Which system of equations can be solved to the number of hats Phil has and the number of combinations that can be made?

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

answer:   y=2x-3

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
