Marco sells hand-decorated clothing online. He charges $15 for each t-shirt and $25 for each sweater. During a two day period, a total of 63 t-shirts and sweaters were sold, the total sales was $1175. If solved correctly which of the following systems of equations yields the number of t-shirts, x, and the number of sweaters, y, that were sold during the two days?

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
