The domain and range for each line is all real numbers. This is because all numbers are possible to input into x and all y values exist.
The slope of the first line is -2/3 and the y intercept is 6. You can reach this conclusion by solving for y (putting it in slope intercept form).
The slope of the second one is 3/4. and the y intercept is all real numbers greater than -4. This is true because it is an inequality and you can find these numbers by solving for y.
The cost of the slice of pizza is $1.00. this is because 3.50 - 2.50 is 1.00.
hope it helps :)

Answer:
$17.97
Step-by-step explanation:
It should be no surprise that the total cost is the sum of the costs of the items being purchased.
We can add the costs of repeated items into the sum several times, or we can use multiplication to find their cost. Most folks use multiplication to find the sum of repeated numbers.
milk + strawberries + bananas
= $3.49 + 2×$4.99 +6×$0.75
= $3.49 +9.98 +4.50
= $17.97

If you're paying attention, you see that this is what happens at the cash register every time you buy something at a store.
Answer:
Step-by-step explanation:
When we have any quantity being multiplied to an expression, we can use the <em>distributive property</em>. The distributive property says that . In other words, we can <em>distribute</em> the outer number inside the parentheses.
Using the distributive property, we can then simplify the given equation as follows:
Finally, you should recall that when multiplying square roots, you can simply bring all the numbers inside of one root. For instance, <em>(note, this does not work for addition or subtraction, only multiplication or division)</em>. Therefore, we can simplify .
Finally, we can combine our answer into
