In 1990, the life expectancy of males in a certain country was 61.3 years. In 1995, it was 64.6 years. Let E represent the life expectancy in year t and let t represent the number of years since 1990 The linear function E(t) that fits the data is E(t)= _t +_ round to nearest tenth,predict for 2005.

Explanation / Answer

(1) incorrect, half of 45 is 22.5
(2) correct
(3) incorrect, when train b passes the same point, train a is 8 miles ahead. distance for train A with respect to the point is Y=40t+8 , distance for train b is y=50t so let Y=y and you'll find t=.8, that is in hours. That's 48minutes past 2:22 which is 3:10
(4) correct
(5)correct
(6)correct
(7)correct
(8)correct
(9)Can't tell, second part not written as inequality
(10)correct
(11)correct
(12)incorrect, -5/6 x = -7/8 -> -40x=-42 -> x=21/20
(13)correct
(14)correct
(15)correct
(16)graph not shown
(17)correct
(18)graph not shown
(19)incorrrect, -19 is less than 19. Arrow should point to smaller number
(20)correct
(21)incorrect. The sale price is 65% of the regular price so 76.15=.65n n=117.15

(22)correct

(23)incorrect, f(-1)=7

(24)correct

(25)correct

(26)correct? in interval notation the domain is (-inf,inf)

(27)incorrect, no sol 6x-5y = -25 is the same as 5y-6x=25

(28)Can't tell, needs rewritten

(29)correct

(30)correct

(31)correct

(32)correct

(33)incorrect, 29.5 or 59/2

(34)incorrect, -84/12=-7

(35)incorrect, arrow starts at -12 with an open circle

(36)correct

(37)correct

(38)correct

(39)correct, although oddly written

(40)incorrect, both x+5y=4 and x+5y=3 can be true at the same time

(41)incorrect, slopes are negative reciprocals of one another and therefore perpendicular. The question wasn't written correctly

(42)correct

(43)correct

(44) correct

(45)incorrect, x=2 is a vertical line going from neg inf to inf

(46)correct, although written incorrectly

(47)correct

(48)incorrect, 200lbs cornmeal and 120lbs of soybeans

(49)correct

(50)correct

(51) they give you 2 points in which you are to find the slope intercept form of the equation. If we let the year 1990 be 0 for the x-direction, then E(t)=.66t+61.3
E(15)=71.2 is the estimated age for the year 2005
