State the value of the discriminate. then determined the number of real roots of the equation

n(7n+8)=-10

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

900 degrees

step-by-step explanation:

your answer would be 12

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,
