How far should the wire be staked from the trunk of the tree? 10 feet 20 feet 29 feet 60 feet 15 ground 25 Grapes cost $1.20 per pound and cherries cost $2.50 per pound. If you spend $7.30 and you buy 3 more pounds of grapes than cherries, Which system of equations represents this? 1.2c + 2.5g = 7.30 and g = c + 3 1.2c + 2.5g = 7.30 and c = g + 3 1.2g + 2.5c = 7.30 and g = c + 3 1.2g + 2.5c = 7.30 and g = 3c Adults cost $5 and children cost $1.50 for admission to the museum. 15 people went and the total cost was $33. How many children went to the museum? 12 9 6 3 Gary threw a ball that followed the quadratic equation h = -16t2 + 45t + 4 where h=height (feet) and t=time (seconds). What was the maximum height of the ball? 35.6 feet 33 feet 2.9 feet 1.4 feet A rocket was lauched following the equation h = -16t2 + 112t where h = height(feet) and t = time (seconds). How long did it take the rocket to hit the ground? 1.2 seconds 3.5 seconds 7 seconds 192 seconds The table represents Loren's bank account balance if she earns 4.5% interest. Which equation represents this? Balance Year y = 9x + 200 y = 200 (0.045)x y = 200 (1.045)x y = (200 + 1.045)x 200 0 209 1 218.41 2 228.23 3 y = 3x y = x + 8 y = x y = x2 What is the parent function to y = 3x + 8 solve for x: 2x + 7 = 5x - 17 -8 3.4 8 -1.7 solve for x: x2 + 16 = 10x 3 0 & 6 2 & 8 -2 & -8 The area of a rectangle is 2x2 + 10x - 12 The length is 2x - 2.
