Can someone please help me??? And please be sure of ur answer :)
Rina8888 [55]

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

The average price (in dollars) to rent a studio in a certain city can be approximated by the equation p=28.2t+644 where t is the
egoroff_w [7]

p = 28.2t + 644\\\\p-644 = 28.2t\\\\\frac{p-644}{28.2} = \frac{28.2t}{28.2}\\  \\t = \frac{p-644}{28.2}

t = \frac{1320.80-644}{28.2} \\\\t = 24

It will take 24 years.
