Step-by-step explanation:
step 1. 4x + 27 + 3x = 90 (definition of a rectangle)
step 2. 7x = 63 (collect like terms. subtract 27 from both sides)
step 3. x = 9 (divide both sides by 7)
A) slope is 7 for 1 and -7 for the other. These lines intersect in 1 point only
b) both equations have slope -2/3 and the same intercept, so it is really only one line...infinite solutions
c) parallel lines have 0 solutions
You will take 44+(40/100 * 44) = 44 + 17.6 = $61.60 ($61.60 is going to be the retail price of the lamp).
