[ 1 ] check whether -3 and 3 are the zeroes of the polynomial x² - 9. [ 2 ] Draw the graph of (i) y = 2x + 5, ( ii ) y = 2x - 5 ( iii ) y = 2x and find the point of intersection on x - axis. Is the x-coordinates of these points also the zero of the polynomial ?

[ 3 ] Draw the graphs of (i) y = x² - x - 6 ( ii ) y = 6 - x - x² and find zeroes in each case. What do you Notice?

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5

the answer, i believe is y-8=1(x+4)

answer: $53750

steps:

list the principal and interest after the n-th year:

n       principal   simple interest

1     12500     375

2     25000     750

3     37500     1125

4     50000     1500

sum: $50000     $3750

total at end of year 4: $53750
