Ionly need the equations not the graphing

x + y ≥ 4

8x + 10y ≤ 70

Step-by-step explanation:

1. State the variables

According to the graph, "Number of green towels" is on the x-axis, and "Number of blue towels" is on the y-axis, so:

let x be the number of green towels.

let y be the number of blue towels

2. Write an equation for the total number of towels.

The sum of number of green towels and the number of blue towels is the total number of towels.

x + y ≥ 4

"She wants to buy at least 4 towels" means she needs 4 or more. Use the ≥ symbol instead of > (which would mean more than 4 towels, not only 4).

3. Write an equation for the money she will spend.

Multiply each variable by the cost of the towel colour. Add them together. Equate the total as 70 because she is only willing to spend 70.

8x + 10y ≤ 70

"She does not want to spend more than $70" means she is willing to spend 70, but no more. This is why we use ≤ and not < (which would mean she would not spend 70, only less than 70).

The equations are x + y ≥ 4 and 8x + 10y ≤ 70.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
