I have no idea how to do this problem i dont know what a is
Answer:
1. is the last one.
2. is the 3rd one.
3. is the first one.
4. is the 2nd one.
Step-by-step explanation:
What you do is you have to get the letter by itself and it all depends on the less than or greater than signs.
For #1. -m+8>6. What you do is you minus 8 from both sides to get -m>-2. You still have a -m so you need to divide both sides by a -1. (<em><u>one thing to remember is when you divide by a negative you have to switch the sign.</u></em>) So your answer will be m<2. That will make the last graph the answer.
For #2. -2p< or equal to -10. What you do is divide by -2. and you need to remember to switch the sign. So your answer is p> or equal to 5.
You will do the same for the other two equations but your answers are.
#1. is the last one graph.
#2. is the 3rd one graph.
#3. is the first one graph.
#4. is the 2nd one graph.
Answer:
L = 12
W = 8
Step-by-step explanation:
Area = L*W
L = W + 4
W = W
Area = 96
W ( W + 4) = 96
w^2 + 4W = 96
w^2 + 4w - 96 = 0
(w - 8)(w + 12) = 0
Only w - 8 = 0 will work
w - 8 = 0 Add 8 to both sides
w = 8
w + 12 = 0 will not work because you have to subtract 12 from both sides to get the value for w.
w = - 12 which has no meaning for garden plots.
So the width = 8 and the length = w + 4 = 8 + 4 = 12
