Answer: x - 5
Step-by-step explanation:
Since, the area of the rectangle =
Length of the rectangle = x+5
Let the width of the rectangle = b
Thus, the area of the rectangle =
⇒
⇒
⇒
Therefore, the expression that shows the width of the rectangle = x-5
Answer:
The feasible region in the attached figure
Step-by-step explanation:
Let
x ----> the number of shirts
y ----> the number of pants
we know that
The cost of the shirts (number of shirts multiplied by the cost of one shirt) plus the cost of the pants (number of pants multiplied by the cost of one pant) must be less than or equal to $80
so
The inequality that represent this problem is
using a graphing tool
The feasible region is the triangular shaded area
see the attached figure

Answer:
y = 4
x = -16
Step-by-step explanation:
this time we should multiply the first equation with -1 because we only need to change its state of negativity
2x + y = -28
-2x - 2y = 24 ➡ -y = -4 ➡ y = 4
if 2x + y = -28 the 2x + 4 =-28 ➡ 2x = -32 x = -16
