Fancy goldfish x cost $3 each and common goldfish y cost $1 each.Graph the function y=20-3x to determine how many of each type o

aniked [119]

The pairs of goldfish Tasha can buy for $20 are $(0,20), (1,17), (2,14),$

$(3,11),(4,8),(5,5),and (6,2)$

Step-by-step explanation:

To find the how many type of goldfish that Tasha can buy for $20 is the set of positive ordered pairs.

Let x denote the number of fancy goldfish.

Let y denote the number of common goldfish.

To find how much goldfish can Tasha buy for $20 is to substitute the value for x in the equation $y=20-3x$

Now, substituting $x=0$ in $y=20-3x$ , we get,

$y=20$

The ordered pair is $(0,20)$

Similarly, substituting $x=1$ ,

$y=20-3(1)\\y=20-3\\y=17$

For $x=2$ ,

$y=20-6\\y=14$

For $x=3$ ,

$y=20-9\\y=11$

For $x=4$ ,

$y=20-12\\y=8$

For $x=5$ ,

$y=20-15\\y=15$

For $x=6$ ,

$y=20-18\\y=2$

Thus, the pairs of goldfish Tasha can buy for $20 are $(0,20), (1,17), (2,14),$ $(3,11),(4,8),(5,5),and (6,2)$

A path 1 m wide is build around a garden that is a 30-meter square. What is the area taken by the path?

Rudik [331]

Answer:

Blue = 116 m^2

Step-by-step explanation:

The area of the path and the square = 30*30 = 900 m^2

The size of the square = 30 - 2 = 28. The square = 28^2 = 784

The path takes up the difference between the two 900 - 784 = 116

The following circle graph represents how the Townsends spend their monthly income. What is the central angle measure of the sec

Varvara68 [4.7K]

The circle graph represents how the Townsends spend their monthly income.

Total central angle of the circle is 360°

Townsend saves 5% of the monthly budget.

Therefore, the central angle measure of the section that represents "Savings" is 5% of the total central angle

= 5% of 360°

= 18°

The central angle measure of the section that represents "Savings" is 18°

Hope this helps ..!!

Thank you :)
