The 10th-grade class officers ordered t-shirts and sweatshirts to sell as a fundraiser. each t-shirt weighed of a pound, and each sweatshirt weighed of a pound. the total weight of the contents of the box was pounds. which equation written in standard form represents the number of t-shirts, t, and the number of sweatshirts, s, that were ordered? 2t + 3s = 175 3s = –2t + 175

In this item, it is unclear of the weights of each of the t-shirt and sweatshirt. We first represent the weights of the t-shirts and the sweatshirts by t and s, respectively. If for example, each t-shirt weighs 2 pounds and each sweatshirt weighs 3 pounds, the answer would be the first choice. 

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
