Answer: The first option.
Step-by-step explanation:
1. The formula for calculate the perimeter is:
P=2l+2w
Where l is the lenght and w is the width.
2. The first perimeter is:
3. If you multiply the dimension by a scale of factor of 2, is the same as write the following expression:
Where is the first perimeter.
4. Then:
Smaller number = X
Larger Number = X + 17
47 = X + (X+17)
47 = 2x + 17
47 - 17 = 2x
30 = 2x
X = 15
Answer:
y = 1
Step-by-step explanation:
You should be able to tell by inspection that the line is horizontal at y = 1.
Answer:
y=2x-4
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=2(x-0)
y+4=2x-0
y=2x-0-4
y=2x-4
