Answer:
Infinite decimals that do not repeat.
Step-by-step explanation:
Repeating decimals can be as fractions where the top and bottom are integers.
Examples: .3333333333333333333333333333333.... can be written as 1/3.
or .19191919191919191919..... can be written as 19/99.
Terminating decimals can also be written as fractions where the top and bottom are integers.
Examples: .11=11/100 or .161=161/1000
Any number that can be written as a fraction where the top and bottom are integers (bottom integer not 0)
is a rational number.
Repeating decimals are infinite. So what I think they mean by infinite here is numbers like or . There are not rational. They cannot be written as a fraction where the top and bottom are integers.
Answer:
Y=-x^2 -2x
Step-by-step explanation:
First distribute -1
Y=-x+0(x-2)
Foil and you get
y= x^2-2x
This is in standard form
Answer:
Cost of 1 ft²: $7
Cost of 1 ft² of geranium: $6
Step-by-step explanation:
Let x be the cost of a ft² of grass
Let y be the cost of a ft² of geranium
13x + 9y = 145
4x + 12y = 100
x + 3y = 25
x = 25 - 3y
13(25 - 3y) + 9y = 145
325 - 39y + 9y = 145
180 = 30y
y = 6
x = 25 - 3(6)
x = 7
