These are my last questions plz help me :)

Reflect the triangle over the y-axis and find the coordinate of the image of point K.

wel

Answer:

Okay, all you have to do is reflect the triangle over the y-axis by finding each of the points distance from the y-axis. For example. If one of your coordinates was (3,2) you would reflect it over to (-3,2). Can you give me point K's coordinates?

Brooklyn Cabinets is a manufacturer of kitchen cabinets. The two cabinetry styles manufactured by Brooklyn are contemporary and

maria [59]

Answer:

See Step by step explanation

Step-by-step explanation:

Objective Function: z

x = number of contemporary style

y = number of farmhouse style

Costs

Carpentry costs:

15*2*x + 15*2,5*y = 30*x + 37,5*y

Painting costs

12*1,5*x + 12*1*y = 18*x + 12*y

Finishing costs

18*1,3*x + 18*1,2*y = 23,4*x + 21,6*y

Total costs:

30*x + 37,5*y + 18*x + 12*y + 23,4*x + 21,6*y

71,4*x + 71,1*y

z = 90*x + 85*y - ( 71,4*x + 71,1*y ) to maximize

z = 18,6*x + 13,9*y to maximize

Subject to:

First constraint:

Hours available in carpentry 3000

2*x + 2,5*y ≤ 3000

Second constraint

Hours available in painting 1500

1,5*x + 1*y ≤ 1500

Third constraint

Hours available in finishing 1500

1,3*x + 1,2*y ≤ 1500

Fourth constraint

Minimum quantity of contemporary style 500

x ≥ 500

Fifth constraint

Minimum quantity of farmhouse style 650

y ≥ 650

General constraints:

x ≥ 0 y ≥ 0 x , y integers

Model:

z = 90*x + 85*y - ( 71,4*x + 71,1*y ) to maximize

Subject to:

2*x + 2,5*y ≤ 3000

1,5*x + 1*y ≤ 1500

1,3*x + 1,2*y ≤ 1500

x ≥ 500

y ≥ 650

x ≥ 0 y ≥ 0 x , y integers

Graph the function. For the function whose graph is shown below, which is the correct formula for the function? y = –x – 1 y = x

rusak2 [61]

You forgot to mention the graph.
So, I make the graph of both given functions and you will compare your graph with them.

First, y= -x-1
put y=0 you get point (-1,0) called x-intercept
put x=0 you get point (0,-1) called y-intercept
join both the points, you will get the graph
Graph is attached in the picture.

Second, y= x+1
put y=0 you get point (-1,0) called x-intercept
put x=0 you get point (0,1) called y-intercept
join both the points, you will get the graph
Graph is attached in the picture.

what is the general equation of cosine function with a amplitude of 3 a period of 4pi and a horizontal shift of - pi

kicyunya [14]

The general form of such an equation will be
$f(x)=A\cos\left(\dfrac{2\pi(x-B)}{C} \right)+D$
where
A = amplitude (3)
B = horizontal shift to the right (-π)
C = period (4π)
D = vertical offset (0)

Your equation will be ...
$f(x)=3\cos\left(\dfrac{x+\pi}{2}\right)$

What inequality has the solutions graphed on the number line?

Verizon [17]

Answer:

x<=3

Step-by-step explanation:

so graphing inequalities on a number line can be tricky but in this case the answer would be x is greater than or equal to three and the reason why is because well first we have the 3 and the circle on the three is filled in meaning the answer of x could possibly be three but the line is also continuing to move to the right therefore meaning the answer could be three but it could also be greater than three therefore your answer is x<=3
