A linear function can be used to model the relationship between x and y that is shown in the table below. x 3 5 7 9
y −2 4 10 16
What is the equation of this linear function?
A
y=3x+3

B
y=3x−11

C
y=6x−2

D
y=6x−20

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

cut 138 centimeters off

step-by-step explanation:

250-112 = 138
