HELP PLEASE ASAP!!!!

For the second question, the answer would be A because the lines intersect at 2 and -1.4. For the first question, t+b is less than or equal to 20 and 15b+8b is greater than or equal to 150 is the answer because Nick can work <u>up to </u>20 hours and needs to make <u>at least</u> $150 per week so that answer fits best. That question is solved mostly by context clues.

-x-3y=14<br> x=4y<br><br><br> solve using substitution
vlabodo [156]
Using
 f1(x)= -x=3t =14

with f2(x) as x=4y

f1(f2)= -x-3y=14
F1(4y)= -(4y)-3y=14
           = -4y-3y=14
           = - 7y=14
           = y= -2

Using the value of y, solve fo rx by entering the value in the original form of f1 or f2

<span>-x-3y=14</span>
-x-3(-2)=14
-x+6=14
x=-8

OR
x=4y
  =4(-2)
  = -8

Thus the solution is (x,y) = (-8,-2)
