Answer:

the third one and the last one is correct

Step-by-step explanation:

we already know the second one is wrong because of it's set up.

just replace the points (-1,7) into each equation. if it doesn't work then move on to the next one. if it does work, then use that same equation except this time to the coordinates (2,4)

How much will it cost to pour a circular slab 18 ft in diameter by 3 in. For a patio if the concrete costs $40.00 per cubic yard
sasho [114]
A circular concrete slab is a cylinder. Vol = pi%2Ar%5E2%2Ah
in this cylinder:
r = 18%2F2 = 9 ft
h = 3%2F12 = .25 ft
:


Find the volume in cu/ft:
V = pi%2A9%5E2%2A.25
V = 63.61725 cu/ft
:
Change to cubic yds; (1 cu/yd = 27 cu/ft) and multiply by $40:
Cost = 63.61725%2F27 * 40
Cost = $94.25


In practical terms , they may require you to buy 3 cu/yds , which is $120

I need help on 34 and 36
aleksley [76]
34. 65 = 3/4c - 7....add 7 to both sides
      65 + 7 = 3/4c...simplify
       72 = 3/4c...multiply both sides by 4/3, eliminating the 3/4 on the left
       72 * 4/3 = c
       288/3 = c
       96 = c

36. -5/2 = 3/4z + 1/2 ...subtract 1/2 from both sides
      -5/2 - 1/2 = 3/4z .... simplify
       -6/2 = 3/4z ....reduce
       -3 = 3/4z....multiply by 4/3. eliminating the 3/4 on the left
      -3 * 4/3 = z
       -12/3 = z
       -4 = z
