Answer:
right-handed gloves and
left-handed gloves were sold.
Step-by-step explanation:
Given: In one month, gloves were sold for a total revenue of
.
right-handed gloves cost and left-handed gloves cost
.
To find: How much of each type of gloves did they sell?
Solution: Let they sell right-handed gloves, and
left-handed gloves.
Now, cost of each right-handed gloves
cost of each left-handed gloves
Total revenue
So, we get
Also, in a month gloves were sold.
So, we get
Now, from we get,
.
Putting in equation
, we get
Now, putting in equation
, we get
Hence, right-handed gloves and
left-handed gloves were sold.
We have to find the parameter a so that (-1,2) is part of the function f(x) = ax²+4.
To check if a point is part of a function, we can replace the values of x and y = f(x) with the coordinates of the point and then, if the equation stays true, then the point is part of the function.
So for (x,y) = (-1,2) to be part of the function y = f(x), this equation has to stands true:
Then, the function would have to be f(x) = -2x² + 4.
We can check with a graph as:
Answer: a = -2
