4. Which equation does NOT have like terms to collect? O 3y - 2(y-1)+y= -42

15t + 19r = 2

8.5d + 7.5 = 100 + 3

0-8(6 - 3) = -56 – 6

Use the function f(x) is graphed below. the graph of the function to find, f(6). -2 -1 1 2

X+y=-4 x-y=2 use elimination with adding and subtraction

An office supply company conducted a survey before marketing a new paper shredder designed for home use. in the survey, 80 % of the people who tried the shredder were satisfied with it. because of this high satisfaction rate, the company decided to market the new shredder. assume that 80 % of all people are satisfied with this shredder. during a certain month, 100 customers bought this shredder. find the probability that of these 100 customers, the number who are satisfied is 69 or fewer.
