5 0

Answer:

slope=0, equation: y=2

Step-by-step explanation:

Diagonal PQ is a horizontal line so it's slope is zero.

Since it is a horizontal line, its equation is just the y-intercept (0 slope), which in this case is y=2.

Answer:

Step-by-step explanation:

2x+5y=12

3x+4y=11

---------------

3(2x+5y)=3(12)

-2(3x+4y)=-2(11)

-----------------------

6x+15y=36

-6x-8y=-22

-----------------

7y=14

y=14/7=2

2x+5(2)=12

2x+10=12

2x=12-10=2

x=2/2=1

x=1, y=2. (1, 2)

---------------------

I just provided you an example of a system of equations and I already solved it for you.

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the
Alex17521 [72]

The equation is that of a parabola, meaning that the maximum (or sometimes minimum) is 1/2 the sum of the solutions found using the quadratic equation.

y = 0 for the 2 solutions to {-b +/- sqrt[b2 - 4ac]} / 2a, where a = -3, b = 152 and c = -1150 from the equation for y. Plug a, b and c into the quadratic formula to get x = 9.2571 and x = 41.4095 as the 2 solutions.

9.2571 + 41.4095 = 50.6666... and the midpoint is 25.3333...

When x = 25.3333..., y = 775.33333.....

To the nearest cent, x=25.33 results in a profit of 775.33.

When x=25.25, Y = 775.31

When x=25.4, Y = 775.32

These are both less than 775.33 when x = 25.33.

Solve 5(2 - x) = 7x - 26 Input ONLY the value of x.
Alexxx [7]

Answer:

x = 3

Step-by-step explanation:

5(2 - x) = 7x - 26

Distribute;

10 - 5x = 7x - 26

Add 5x to both sides;

10 = 12x - 26

Add 26 to both sides;

36 = 12x

Divide both sides by 12;

x = 3
