This is the same as saying x*y+25=0.

Also, x*y=-25.

The solution (if you had to find it) would be -5 and 5.

To graph, it would be y=-25/x

Edit: This can be simplified down to y=-5 since it is a constant so it would be a straight line on the y-axis down at -5.

Answer: 168 toads

Step-by-step explanation:

First we need to find the area of the garden. Area = length x width

Area = 12m x 7m = 84 m²

2 toads/ 1 sq m

84(2) = 168

Mary wants to buy candies with an amount of money she has in her pocket. we know that if she had $3.20 more money she could bu

liubo4ka [24]

Answer:

the price per candy is $0.16

and she has $16.00 in her pocket.

Step-by-step explanation:

x = the money in her pocket.

y = the price per candy

x + 3.2 = 120×y

x - 2.4 = 85×y

y = (x - 2.4)/85

x + 3.2 = 120×(x - 2.4)/85 = (24x - 57.6)/17

(17x + 17×3.2)/17 = (24x - 57.6)/17

17x + 54.4 = 24x - 57.6

54.4 = 7x - 57.6

112 = 7x

x = 16

y = (16 - 2.4)/85 = 13.6/85 = 0.16
