Pretty sure it’s C. Quadratic
Answer:
2: 8
3: 14
4: 4
Step-by-step explanation:
the first one i couldnt see it clearly!
First you need to change the equation to slope intercept form. You would get
y = 2x - 8
This equation gives us the answers to question c and d. The y intercept is 8 and the slope is 2. Now using this information we can now graph the equation. Since the y intercept is 8 this means that the line you will draw on the graph is going to pass through the y axis at point (0,8). So put a dot 8 spots up from the center. Then from there we use the slope to find the other points. Our slope is 2, so this means that in order to get to the next point you must go up 2 and to the right 1. Once you’ve got your next point continue until you run out of space. The to fill in the line to the left of your first point you have to do the reverse. Go down 2 and to the left 1 until you run out of space. Connect the points. Now for question b notice where your line passes through the x axis (the horizontal line on the graph) and this should be 4 spaces away from the center. Since this point is to the left of the center it’s going to be negative. So your answer would be -4.
Answers and Step-by-step explanations:
(a)
We need to figure out the amount (or total cost) for each size candy given that they sell a certain number of each box. For the small box, we're given the cost is $4.70, while the large box is $7.00.
We buy x of the small box, so the total amount should be 4.70 * x, or just 4.70x. We buy y of the large box, so the total amount should be 7.00 * y, or just 7y.
So on the table, the top value should be 4.70x, and the bottom value should be 7y.
(b)
The total number of boxes sold was 45 boxes. Remember that x boxes were small and y boxes were large. Since the number of small boxes plus the number of large boxes is equal to the total of 45, we can write:
x + y = 45
(c)
The total cost was $269, so we can write this as the sum of the amounts that we found in part (a):
4.70x + 7y = 269
