2. Simone has discovered a blow-out sale at a shop in the mall. The cost of 2 sweaters, 5 shirts, and 3 pairs of
pants is $172. The cost of 5 sweaters and 8 pairs of pants is $269. The cost of 4 shirts and 1 pair of pants
-is-574-If-x-represents-sweaters-y- represents-shirts, and-2-represents pants, which
systems of equations can be
used to determine the sale price of the sweaters, the shirts, and the pants?
a.
2x + 5y + 3z = 172
5x + 8z = 269
4y+z=74
c. 2x + 5y + 3z= 172
5x+y+ 8z = 269
x + 4y + z = 74
b.
x+y+z= 172
X + 2 = 269
y+z=74
d. 2x + 5y + 3z= 172
5x - 8z=269
4y - z=74

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m
