Answer:
I buy 4 food items and 7 non-food items from the store.
Step-by-step explanation:
The food items in the store are sold at $3 each and the non-food items are sold at $3 plus 5% tax.
So, the cost of each non-food items will be dollars.
If we consider that I buy 1 food item, then I buy $(34.05 - 3) = $31.05 of non-food items which is not a multiple of $3.15.
If I buy 2 food items, then I buy $(31.05 - 3) = $28.05 of non-food items which is again not a multiple of $3.15.
If we consider that I buy 3 food items, then I buy $(28.05 - 3) = $25.05 of non-food items which is again not a multiple of $3.15.
If I buy 4 food items, then I but $(25.05 - 3) = $22.05 of non-food items which is finally a multiple of $3.15 as (3.15 × 7) = 22.05.
Therefore, I buy 4 food items and 7 non-food items from the store. (Answer)
Answer:
Width: 9 inches
Step-by-step explanation:
1. We can see that the height increased by 6 inches, provided a difference of 15 and 9. If the question states that the frame's dimensions were proportionately enlarged, perhaps the height's enlargment could be benificial
2. If we were to take a ratio where the increased height is over the previous height (height enlargment/prior height) that would be 6/9, or in other words, can be simplified to be 2/3
3. We can see that if the width were to be enlarged, we might be able to determine how much it should be enlarged through a proportionality, provided <em>the frame's dimensions are proportionately enlarged.</em> Now if x ⇒ the width enlargment: 2 / 3 = x / 5.4
4. Through cross multiplication, let us solve for x:
2 * 5.4 = 3 * x,
10.8 = 3 * x,
x = <em>3.6 inches by which the width should be enlarged</em>
5. If we are to determine the new width of the frame after enlargment, add <em>5.4 to 3.6 ⇒ the width of the frame ⇒ 9 inches</em>

Answer:
Both the domain and range are the set of all real numbers. For the absolute value function f(x)=|x| f ( x ) = | x | , there is no restriction on x . ... For the cubic function f(x)=x3 f ( x ) = x 3 , the domain is all real numbers because the horizontal extent of the graph is the whole real number line. this is the best i can do if its not helpful i guess u can ask ur teacher.
