Y= 3.5t+2
you spent 3.5 hours on each test
(3.5(4)+2= 16)
Answer:
Im pretty sure the function is increasing from x = -2 to x = -1
Step-by-step explanation:
If each of the 36 cans of vegetables were corn the cost would be 0.40*36 or $14.40. This is obviously not enough. For every tomato can you buy instead of corn the price goes $0.80 -$0.40 or $0.40 up. Knowing this all you need is to find how many corns to replace. To do this find the difference between the real cost and the all corn cost. This is $20.8-$14.4 or $6.40. Now to find the number of corns to be replaced just divide this by 0.40 to get 16. That means 16 corns need to be replaced by tomatoes. So there is 20 cans of corn and 16 cans of tomatoes. The answer is 20 cans of corn.
Based on the graph which models the function at x = -2 (see attachment), the corresponding y-value is y = 3.
<h3>What is a function?</h3>
In Mathematics, a function can be defined as a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.
In this scenario, there are several values (points) on the given linear graph expressed as a coordinate (x, y). Hence, the x-values on the x-axis is directly proportional to the y-values on the x-axis.
By critically observing the graph which models the function at x = -2 (see attachment), we can logically deduce that the corresponding y-value is three (3).
