identify the point of intersection, using one of the following methods: Elimination, subsitiution, graphing X starts at 0 and goes up by 10 each rep for up to 15 reps To find y for the first its .4(X)+50 To find y for the second line its 4.4(X)+0

Best ResponseYou've already chosen the best response.0just set 4.4x=.4x+50 4.4x.4x=50 4x=50 x=50/4 x=25/2 so y=4.4x=4.4(25/2)=44/10(25/2)=22/5(25/2)=5(11)=55 so they intersect at (25/2,55)

Best ResponseYou've already chosen the best response.0to find where they intersect all i did was set the two lines equal to each other i want to find the x when the two lines are the same (so the equal sign means that) and i solved for x and then it didn;t matter which line i used after that to find y both lines would give me the same y

Best ResponseYou've already chosen the best response.0yes i just replaced that one y with y=4.4x substitution

Best ResponseYou've already chosen the best response.0would i get full credit for expaining work also what is the function of the two

Best ResponseYou've already chosen the best response.0in the directions about it said to find the intersection it is (25/2,55) i don't know what you mean by the function of the two?

Best ResponseYou've already chosen the best response.0ok its function for 1st line and function for 2 and if the points matter two of them from each are (1) 10,52 20,54 (2) 10,44 20, 88

Best ResponseYou've already chosen the best response.0wait are you saying for the first line the some of the ordered pairs are {(10,52),(20,54)} 2nd line {(10,44),{20,88)} ?

Best ResponseYou've already chosen the best response.0by the scale they gave us these are for each 10 bottles but for the second part which i started the question it is ok because plugin them into a graph got around what you said.

Best ResponseYou've already chosen the best response.0the above are some of the ordered pairs on the line right? you are trying to get me to check your lines, correct?

Best ResponseYou've already chosen the best response.0the function is what im clueless about and i think it has some relation with that right?

Best ResponseYou've already chosen the best response.0are the following ordered pairs on a line: (10,52) and (20,54) are the following ordered pairs on the other line: (10,44) and (20,88)?

Best ResponseYou've already chosen the best response.0ok so since we know two points on the first line, the slope is \[\frac{5452}{2010}=\frac{2}{10}=\frac{1}{5}\] so we have y=1/5*x+b we need to know the yintercept which we are calling b in the line before we know a point on the line (10,52) x=10 and y=52 so 52=1/5*10+b we can solve for b 52=2+b 50=b so the equation of line 1 is y=1/5*x+50 now second line we know two points on it as well so we can find the slope the slope is \[\frac{8844}{2010}=\frac{44}{10}=\frac{22}{5}\] so we have y=22/5*x+b we know a point on this line so we can find the yintercept which we called b in the line before x=10 y=44 44=22/5*10+b so we can solve for b 44=22(2)+b 44=44+b b=0 so the equation of the line is y=22/5*x

Best ResponseYou've already chosen the best response.0so we have Line 1: y=1/5*x+50 and Line 2: y=22/5*x 22/5*x=1/5*x+50 (by substitution) 22/5*x1/5*x=50 21/5*x=50 x=50*5/21 x=250/21

Best ResponseYou've already chosen the best response.0so y=22/5*250/21=1100/21

Best ResponseYou've already chosen the best response.0so the 25/2,55 changed?

myininaya

Best ResponseYou've already chosen the best response.0so the point of intersection is (250/21,1100/21)

Best ResponseYou've already chosen the best response.0yes we have different lines so the point of intersection will be different

Best ResponseYou've already chosen the best response.0are you sure its not closer because on the graph i made its near the start

Best ResponseYou've already chosen the best response.0? i found the lines by the ordered pairs you gave me those ordered pairs lie on those two lines right with (10,52) and (20,54) lying on one line and with (10,44) and (20,88) lying on the other?

Best ResponseYou've already chosen the best response.0yea but 10 is 10 of x you can plug 1,2,3, 150
