2x + y = 2 x + 2y = 2
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

step-by-step explanation:

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
