She needs 23 boxes because 22.25 boxes doesn’t make sense.
The answer is 23 boxes not 22
For this kind of problem is nneded to replace a letter b by a numerical value. Thne find the missing variable x .
then replace b = 5 in equality
4(5x - 3) = 8 ( x-2)
now eliminate parenthesis, by PEMDAS method
4•5x - 3•4 = 8x - 8•2
20 x - 12 = 8x - 16
now reorganize letters and numerical values
20x - 8x = -16 + 12
12x = -4
then finally x= -4/12 = -1/3
Answer:
(2, 1).
Step-by-step explanation:
x^2 - 4x + 5 = 0
(x - 2)^2 - 4 + 5 = 0
(x - 2)^2 + 1 = 0
The vertex is at (2, 1).
Answer:
Please check the explanation.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
k = y/x
here k is the constant of variation.
From the table,
substitute x = -3, y = -4 in the equation
k = y/x
k = -4/-3
k = 4/3
substituting x = -2, y = -1
k = y/x
k = -1/-2 = 1/2
substituting x = -1, y = 2
k = y/x
k = 2/-1 = -2
substituting x = 0, y = 5
k = y/x
k = 5/0 = ∞
substituting x = 1, y = 8
k = y/x
k = 8/1
k = 8
substituting x = 2, y = 11
k = y/x
k = 11/2
substituting x = 3, y = 14
k = y/x
k = 14/3
It is clearly visible that there is no constant of variation because the ratio y = k/x is variating for different ordered pairs.
Thus, It is clear that none of the answers in the answer choices represent the constant of variation in this relation.
