Answer:
5.50x + 2y ≤ 18
Step-by-step explanation:
Romona has a total of $18 and she has to spend it on dog food.
Dry god food cost $5.50 per bag and wet dog food cost $2.00 per can.
We have to write an inequality to show the above condition.
Let the number of dry and wet dog food she buys be x and y.
The total cost of dog food must be less than $18.
Then,
5.50x + 2y ≤ 18
This is the required linear inequality.
Answer:
a convex nonagon
Step-by-step explanation:
I believe you are expected to simplify. To do this all you do is group like terms (x, x², x³ etc.) and then simplify the coefficients.
13. 10z + 7z - 19z² - 5z² - 17z
first you can rearrange and group like terms (remember the bring the sign in front of each term with it). I would do it like this:
-19z² - 5z² +10z + 7z - 17z
Now simplify the coefficients:
-24z² + 0z
you can omit the 0z and your simplified answer is
-24z²
Main thing to remember here is that z and z² cannot be simplified together, nor can any variable that has an exponent because the exponent makes them differ.
