Barney & Noblet customers can choose to purchase a membership for $25 per year Members receive 10% off all store purchases
Law Incorporation [45]

Answer:

  1. $70
  2. y = 25 + 0.9x
  3. $250

Step-by-step explanation:

1. 10% of $50 is $5, so the purchases would come to $50 -5 = $45. Added to the $25 membership fee, the total cost for the year would be

  $45 +25 = $70

2. The member pays $25 even if no purchases are made. Then any purchases are 100% - 10% = 90% of the marked price. So, the total is ...

  y = 25 + 0.90x

3. $25 is 10% of $250, so that is the amount the member would have to purchase to break even on cost.

If you like, you can compare the cost without the membership (x) to the cost with the membership (25+.9x) and see where those costs are equal.

  x = 25 +0.9x . . . . . x is the spending level at which there is no advantage

  0.1x = 25 . . . . . . . . subtract 0.9x

  25/0.1 = x = 250 . . . divide by 0.1

the measure of the angle is 88 degrees greater than its complement. what is the measure of the complement?
vazorg [7]
Let the angle be x and it's complement be c.

Then, x = c + 88 and x + c = 90

Substitute the first equation in the second.

(c+88) + c = 90
2c+88 = 90
2c = 2
c =1 

Compliment = 1
Angle = 89

Is the figure an example of a segment?
Radda [10]

Answer: yes, it extends infinitely in opposite directions

Step-by-step explanation:

Examples of line segments include the sides of a triangle or square. More generally, when both of the segment's end points are vertices of a polygon or polyhedron, the line segment is either an edge (of that polygon or polyhedron) if they are adjacent vertices, or otherwise a diagonal.

Irina-Kira [14]

Answer:

x = -6       x=5

Step-by-step explanation:

x^2 +x -30 =0

Factor

What two numbers multiply to -30 and add to 1

6 * -5 = -30

6-5 =1

(x+6) (x-5) =0

Using the zero product property

x+6 =0    x-5=0

x+6-6=0-6    x-5+5=0+5

x = -6       x=5
