Answer: There are 22 whole cheese sandwiches that can be prepared.
Step-by-step explanation:
Since we have given that
Number of slices of bread = 44
Number of slices of cheese = 75
According to question, a cheese sandwich consists of 2 slices of bread and 3 slices of cheese.
So, we need to find the number of whole cheese sandwiches that can be prepared.
Number of sandwich containing only slice of bread is given by
Number of sandwich containing only slice of cheese is given by
As we know that each sandwich should contain both slice of bread and slice of cheese.
So, Least of (22, 25) = 22
Hence, there are 22 whole cheese sandwiches that can be prepared.
Answer:
Step-by-step explanation:
Given equation is,
y = 3x² - 6x + 11
a). y = 3x² - 6x + 11
= 3(x² - 2x) + 11
= 3(x² -2x + 1 - 1) + 11
= 3(x² - 2x + 1) - 3 + 11
= 3(x - 1)² + 8
Comparing this equation with y = a(x - b)² + c
a = 3, b = 1 and c = 8
b). For minimum value of x,
Since, vertex of the graph is given by (b, c),
Minimum value of x will be,
x = b
x = 1
c). Vertex of the parabola → (b, c)
→ (1, 8)
For y-intercept,
By substituting x = 0 in the equation,
y = 3(0 - 1)² + 8
y = 11
Now we can sketch the graph by using the table of input - output values.
x -2 -1 0 1 2 3
y 35 20 11 8 11 20
