Answer:
(-2, -4), (-1, -1), (0, 0), (1, -1), (2, -4)
Step-by-step explanation:
You plug in x values to get the y values are dot-in the points!
y = -x^2
You plug in -2 and get -(2)^2 = -(4) = -4
Same thing with all other values.
Answer:
A sandwich shop offers:
Bread: 1 , 2
Meat: 1 , 2 , 3 , 4
Cheese: 1 , 2 , 3
Choose one to be your starting point. For example, choose Bread. You only choose one of each, so:
Bread 1, Meat 1, Cheese 1
Bread 1, Meat 1, Cheese 2
Bread 1, Meat 1, Cheese 3
etc. etc.
However, note that there is an easier way to solve it. In this case, you can use the <em>Fundamental Principle of Counting</em>, which each total number of choices are added together.
Multiply them:
Bread x Meat x Cheese = 2 x 4 x 3 = 24
There are 24 different types of sandwiches that can be made if only one of each is chosen.

Answer:
Step-by-step explanation:
this ratio of (1/8) to (1/4) can be written as a fraction
however, since we want to find out how much salt is needed for one teaspoon of baking soda, salt is the numerator (top) of the fraction and baking soda is the denominator (bottom) of the fraction
(1/8)/(1/4)
(1/8)x(4/1) when you divide fractions the second fraction switches the top and bottom
(1/8)x4
4/8
1/2
1/2 or 0.5 teaspoons of salt are needed per teaspoon of baking soda
