Answer:
(d) y ≤ -7
Step-by-step explanation:
The solution is found by dividing by the coefficient of y. Since that is a negative number, the sense of the comparison is reversed.
-8y ≥ 56
(-8y)/(-8) ≤ 56/(-8)
y ≤ -7
Answer:
4.6 cubic feet
Step-by-step explanation:
take 34 1/2 gallons and divide it by 7 1/2 gallons
34.5 divided by 7.5 = 4.6
Answer:
3/4
Step-by-step explanation:
Absolute value is the distance from zero.
Answer:p = (2100 - x)/25
Step-by-step explanation:
According to the law of demand, when the price,p of the brand of MP3 players is is high, the quantity,x of the brand of MP3 players demanded would be low and when the price,p of the brand of MP3 players is is low, the quantity,x of the brand of MP3 players demanded would be high.
To derive the demand equation, we would apply the slope intercept form of equation which is expressed as
y = mx + c
Where
m = slope
c = intercept
The slope, m would be
(y2 - y1)/(x2 - x1)
Slope = (1100 - 100)/(40 - 80) = 1000/-40
Slope = - 25
To find the y intercept, we would substitute m = - 25, y = 1100 and x = 40 into y = mx + c. It becomes
1100 = - 25 × 40 + c
1100 = - 1000 + c
c = 1100 + 1000 = 2100
y = - 25x + 2100
Therefore, the demand equation is
x = - 25p + 2100
25p = 2100 - x
p = (2100 - x)/25
Answer:
A
Step-by-step explanation:
It looks like M is composed of all real numbers and that U = R also means its composed of all real numbers. This means that M and U are equal and both are composed of all real numbers.
To define the complement of M, it includes all values which are not in M. However, since M already has all real numbers and U doesn't have any values that M doesn't then the complement is nothing. It is an empty set with no items in it. This means A is the correct answer.
