Mary is making pillows for her Life Skills class. She bought 2 1/2yards of fabric.
Her total cost was $15. What was the
cost per yard?

The cost per yard is $6

Step-by-step explanation:

In order to find out the cost per year, we have to take the total cost and divide it by the number of yards, and so we get...

15 / 2.5 = 6

Therefore the cost of 1 yard is $6.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
