HELP ME QUICK: Suppose AB has one endpoint at A(0, 0). If (5, 3) is the midpoint of AB, what are the coordinates of point B?

Answer:

<h3>           B(10, 6)</h3>

Step-by-step explanation:

If P is midpoint of AB and:  A(0,\,0)\,,\quad P(5,\,3)\,,\quad B(x_B,\,y_B)

then:

x_P-x_A=x_B - x_P\qquad\quad\ \wedge\qquad y_P-y_A=y_B - y_P\\\\ 5-0=x_B-5\qquad\quad\wedge\qquad 3-0=y_B -3\\\\ x_B=5+5\qquad\qquad\wedge\qquad\ \ y_B=3+3 \\\\ {}\quad x_B=10\qquad\qquad\wedge\qquad\qquad \ y_B=6

Y=-3x+9<br> y=-x-5 <br><br> what is the solution for the system of equations?
alexandr402 [8]

Our system of equations is:

y = -3x + 9

y = -x - 5


To solve this system of equations, we are going to use substitution. This means that we are going to substitute the second equation into the first equation since both are already solved for y in terms of x.


y = -3x + 9

-x - 5 = -3x + 9


Now, we must simplify by moving all of the constant terms to one side of the equation and all of the variable terms to the other side.


-x - 5 = -3x + 9

2x - 5 = 9

2x = 14


Finally, to undo the multiplication between the coefficient 2 and the variable x, we must divide both sides by 2 to get the variable x alone.


x = 7


Next, we must substitute in this value we have solved for x into one of the original equations to solve for the other variable, y.


y = -3x + 9

y = -3(7) + 9


To simplify, we must multiply through the parentheses and combine like terms by addition.


y = -21 + 9

y = -12


Therefore, your final answer is x = 7 and y = -12, or as an ordered pair (7, -12).


Hope this helps!

A cube has side length 4 centimeters is 25% full of sand.what is the volume of the sand?
mariarad [96]
Answer 16 cubic cm (cm^3)

Volume of a cube is L x W x H
Since the cube has equal sides of 4 cm
4 x 4 x 4 = 64 total volume of cube

Now we take 25% of the cubes total volume to find the portion filled with sand
25% x 64 = 16 cubic cm

A bakery has fixed costs for retail space, electricity, and appliances of $15,000. The variable cost of baking a cookie is 0.25
den301095 [7]

Answer:

Step-by-step explanation:

That $15,000 sounds like an annual amount, not a monthly or weekly amount.  In the absence of clarification of this, I will include that $15,000 in the following calculations:

Let the # of cookies baked be z and the number of cakes be k.

Then:

Total cost = $15,000 + ($0.25/cookie)z + ($3.53/cake)k

In this specific case, where the number of cookies is z and the number of cakes is k, the formula  

Total cost = $15,000 + ($0.25/cookie)z + ($3.53/cake)k

becomes ...

Total cost (z, k)  = $15,000 + ($0.25/cookie)(400) + ($3.53/cake)(200),

and this works out to:

TC (z, k) = $15,000 + $100 + $706 = $15,000 + $806 = $15,806.

No cakes or cookies could be good enough to warrant production costs that high!

Double-check to ensure that you have copied this problem down completely and accurately.

The wall is 4m long and 3m board.If it has volume of 720000cm.find the height of the wall​
OLEGan [10]

Answer:

Step-by-step explanation:

l = 4m = 400 cm

w = 3m = 300 cm

Volume  = 720000 cubic cm = 720000

length * width * height = 720000

400 *  300 * height = 720000

height = 720000 / 400 * 300 = 72/12 = 6 cm
