Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of days that fluffy eats wet food in a week and y represents the number of days that fluffy eats dry food in a week.
Hence:
x + y = 7 (1)
Also, John wants to spend at most $9.00 on cat food each week. Hence:
1.5x + 0.75y ≤ 9 (2)
The list of possible points after solving graphically are:
(0,7), (6,0), (0,12) and (5, 2). If x,y > 0, then the point that satisfies the inequality is:
(5, 2) i.e. 5 wet food and 2 dry food
Refrection across the y-axis changes the function to y = |-x|.
Vertical stretch by a factor of 1.5 changes the graph to y = 1.5|-x|
Shifting the graph by 4 units downward changes the graph to y = 1.5|-x| - 4
Required equation is y = 1.5|-x| - 4
Answer:
x = - 7, + 7
Step-by-step explanation:
The denominator of h(x) cannot be zero as this would make h(x) undefined. Equating the denominator to zero and solving gives the values that x cannot be.
solve :
x² - 49 = 0 ⇒ (x - 7)(x + 7) = 0 ⇒ x = ± 7
The domain is valid for all x ∈ R , x ≠ - 7, + 7

Answer:
Option B is correct
The maximum revenue that the company can make from the treadmill sales is, $81,000
Step-by-step explanation:
Let x represent the number of treadmill x sold and y represents the number of treadmill y sold
As per the statement: Three times the number of treadmill y sold must be less than or equal to twice the number of treadmill x sold.
⇒
......[1]
Also, it is given that the company has at most 100 treadmills to sell.
⇒
using a graph tool for equation [1] and [2] as shown in figure given below;
⇒ the solution is the shaded area
The maximum revenue that the company can make is for the point, (60, 40)
⇒ x = 60 treadmills
and y = 40 treadmills
Maximum Revenue = 
Therefore, the maximum revenue that the company can make from the treadmill sales is, $81,000
