1. is the equation true, false, or open? explain. 8+4=-5+7. 2. which ordered pair is a solution of the equation y=-11x+4? (show your work) a. (0,-7) b. (-1, -7) c. (1, -7) d. (2,26) 3. complete the table and state the rule. input: output: 0 0 -- 3 2 -- 3 9 -- -- 5 15 6 -- 4. a plumber charges $65 per hour to fix a leak. what is an equation that relates the total cost of a leak repair (c) to the number of hours, (h), it takes the plumber to fix the leak. 5. solve for x: (show work) 2x=-6 6. solve for j: (show work) 8j-5+j=67 7. solve for m (literal equations): y=mx+b

1) 8 + 4 = -5 + 7

     12   =    2

        FALSE

2) y = -11x + 4

(0, -7):   -7 = -11(0) + 4   ⇒   -7 = 0 + 4   ⇒   -7 = 4   False

(-1, -7):  -7 = -11(-1) + 4   ⇒   -7 = 11 + 4   ⇒   -7 = 15   False

(1, -7):  -7 = -11(1) + 4   ⇒   -7 = -11 + 4   ⇒   -7 = -7   True

(2, 26): 26 = -11(2) + 4   ⇒   26 = -22 + 4   ⇒   26 = -18   False

C

3) Input       Output

     0                0

    1                 3            

    2                6  

    3                 9

    4                12  

    5                 15

    6                 18  

Rule: input is being added by 1, output is 3 times x

4) c = 65h

5) 2x = -6

    x = -3

6) 8j - 5 + j = 67

        9j - 5 = 67   added like terms (8j + j)

             +5   +5

        9j      = 72

        j      = 8

7) y = mx + b

  -b          -b  

y - b = mx

b

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
