K so for this problem, all you have to do is pluck in those x-values and solve. We'll do them one by one :) So when we put in x=0.4 we get, y=3(0.4)+12 (Now we do order of operations and multiply 3*0.4 first) y=1.2+12 and now we add this together and get y=13.2 Now we do the same thing with the other 3 and get: y=3(0.6)+12 y=1.8+12 y=13.8 Now 2 more left: y=3(1.8)+12 y=5.4+12 y=17.4 And the last one: y=3(2.2)+12 y=6.6+12 y=18.6 So by doing this we now know that all our y-values are 13.2,13.8,17.4,18.6 and that's the second answer :)
ur teachin me stuff,u ready for round 3?
Sure and hey you can just stay here if you want :) I just like helping people learn more about getting medals so it'll be easier for the both of us as well :)
idk what this is trying to get me to do?? John began his job making $25 the first day. After that he was paid $6.75 per hour. Write the linear equation for this problem in y=mx+b form.
Oh okay, so it wants us to put the information you wrote above in an equation that looks like that. So every hour we will get $6.75 so that number will always be constant. Since we don't know how many hours John works, that'll be a variable, x. So so far we have y=$6.75x. Now it also said he got an automatic $25 on the first day so the equation is y=$6.75x+25 :) Did you get it? :)
oh x is how many hours and thats multiplied by how much we get n a hour??
Well we can't solve the equation, we can only make one. To solve it, the problem would have had to say how many hours John actually worked.
now its aking me to do stuff with the same prob but with a t graph ;( idk this stuff
John began his job making $25 the first day. After that he was paid $6.75 per hour.Make a T-table for the equation for this, using the x-values: 0, 20, 40. Type in the ordered pairs you get as your answer, in this form: (0, number), (20, number), (40, number).
He gets 6.75 an hours, and we don't know how many hours he worked so that's why we do y=6.75x+25. the X in the equation above is the amount of hours John worked. But we can't put a number for x because the problem doesn't tell us how many hours John worked.
i get that but not this
Oh I get it. You have to make a table. Now though you have to put 0,20, & 40 as the x-values and solve for your answer.
So our equation we have is y=$6.75x+25. We will pluck in 0,20 & 40 one by one to see what we get. y=$6.75(0)+25 y=0+25 y=$25. y=$6.75(20)+25 y=135+25 y=$160 y=$6.75(40)+25 y=270+25 y=$295
|dw:1347661718902:dw| I'm pretty sure that's what it's asking for.
