Step-by-step explanation:
Since we have given that
Material needed to make a pillow cover is given by

We need to calculate the material which will be needed to make 9 pillows covers.
So, we use the "Multiplication Operation" as we need the value for more pillow covers :


Y= D.5 __________________________________

When photocopying a credential, it is first enlarged to triple and subsequently the resulting copy is halved. What is the final effect on the original credential? If the credentials is a rectangle of 10 by 6 cm. What area will you have in the first photocopy? And in the second?
Original: 10 by 6 cm ; Area = length * width = 10 x 6 = 60 cm²
first copy: enlarged to triple
10 x 3 = 30
6 x 3 = 18
30 x 18 = 540 cm²
second copy: halved
30 x 1/2 = 15
18 x 1/2 = 9
15 x 9 = 135 cm²
Answer:
y = -3/2x + 6
Step-by-step explanation:
Parallel lines have the same slope so slope is -3/2
Using (4,0)
y = mx + b
0 = -3/2(4) + b
0 = -6 + b
b = 6
so y = -3/2x + 6
