Answer:

x = 4

y = -7

Step-by-step explanation:

y = -2x + 1

4x + y = 9

4x + (-2x + 1) = 9

4x - 2x + 1 = 9

2x + 1 = 9

2x = 9 - 1

2x = 8

x = 8/2

x = 4

4x + y = 9

4(4) + y = 9

16 + y = 9

y = 9 - 16

y = -7

Answer:

325 square inches

Step-by-step explanation:

Consider the attachment below for further reference. Ideally we would split this figure into parts, and solve as demonstrated by the attachment. I have labeled each rectangle as rectangle 1, rectangle 2, rectangle 3 etc. ;

$Rectangle 1 Area = 17 in * 5 in = 85 square in\\Rectangle 2 Area = ( 17 in - 5 in ) * 14 in = 168 square in,\\Rectangle 3 Area = ( 12 in - 3 in ) * 8 in = 72 square in\\\\Total Area = 85 + 168 + 72 = 325 square inches$
