Average price of a CD/ mp3 player is : $ 150
Meanwhile , average price of an mp3 player is : $50
To buy 4 cd/mp3 player, we need $ 150 x 4 = $ 600
To but an mp3 player, we need $50 x 3 = $ 150
The total is $ 750
Hope this helps
Answer: 25.67°
Step-by-step explanation:
Tangent = opp/adj
7/3 = 2.333
To get degrees, take tan^-1 of 2.33 25.666. round to 25.7 or 25.67°
Write as a system y= 2 x + 2.4x - 2y = 4
{y = 4
{2x + 2.4x - 2y = 4
Substitute the value of y into the equation
2x + 2.4x - 2 x 4 = 4
Solve the equation
x= 30/ 11
A possible solution is
(x, y) = (30/11, 4)
Check the solution
4 = 2 x 30/11+ 2.4 x 30/11 - 2 x 4 = 4
Simplify the expression
4 = 4 = 4
The ordered pair is a solution
(x, y) = ( 30/11, 4)
Solution:
D is the correct option.
Explanation:
The equation for the given line is y − 1 = 4(x + 3). Let us convert this equation in slope intercept form y= mx +b, where m is slope and b is the y-intercept.
Thus, the slope of this line is 4.
Now, we know that the slope of parallel lines are equal. Hence, the slope of the required line is same as the slope of the given line.
Hence, the slope of the required line is m = 4
It passes through the point (4,32).
The point slope form of a line is given by
Therefore the equation of the line is y = 4x+16
D is the correct option.
F (x,y) = 2.30x + 3.10y
The constraints are described with the following inequalities:
2x + 2y < = 120
3x + 4y < = 160
The corner points are: ( 0, 40) and (40/0.75, 0)
F (0,40) = 3.10 * 40 =$124
F (40/0.75,0) = (40/0.75) * 2.30 = $122.67
To maximize the profit they should sell 40 Turkey Specials.
So your answer should be C.
