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.

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
