Sam was given the following question and asked to solve it: 20- 10/2 . First he did 20-10 and got 10, then he divided 10 by 2 and got 5 as his answer. Is he correct? If not, what is his error? Explain your answer.

anser is a

step-by-step explanation:

negitive slope

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
