Answer:
what do you mean? i dont get it
Step-by-step explanation:
In this question, importance has to be given to all the information's provided. Based on these information's the answer to the question can be reached.
Total length of ribbon = 1.5 yards
1 yard = 3 foot
1.5 yards = 3 * 1.5 feet
= 4.5 feet
So the total length of the ribbon is 4.5 feet.
Now
Cost of 1 foot of ribbon = 10 cents
Then
Cost of 4.5 feet of ribbon = 10 * 4.5 cents
= 45 cents.
= 45/100 dollars
= 0.45 dollars
So the cost of the total ribbon in dollars is $0.45.
The origin being O, the three axes are:
OX , OY and OZ
1) Point-slope form
(y-y1)=m(x-x1)
m= - 3,
point (3,-4), so x1 = 3, y1 = - 4.
(y+4)= -3(x- 3)
2)Point-slope form
(y-y1)=m(x-x1)
m= - 3/4,
point (4,5), so x1 = 4, y1 = 5.
(y-5)= - 3/4(x-4)
