First, graph the three inequalities:  x ≥ 5  ,  y ≤ 10  ,  2x - y  ≤ 8

Next, look for the 3 intersections (vertices) of the lines: (5, 2)  ,  (5, 10)   ,  (9, 10)

Finally, input the vertex coordinates into P = 4x + 5y and look for the biggest #.

(5, 2):  4(5) + 5(2)  = 20 + 10  = 30

(5, 10): 4(5) + 5(10)  = 20 + 50  = 70

(9, 10): 4(9) + 5(10)  = 36 + 50  = 86

Answer: maximum profit = 86

Write the equation for 5x + 2y = 3 in slope-intercept form.
Vikki [24]

Answer:

B. y = -5/2x +3/2

Step-by-step explanation:

5x + 2y = 3

We want to get this in the form

y = mx +b where m is the slope and b is the y intercept

Subtract 5x from each side

5x -5x+ 2y =-5x+ 3

2y = -5x+3

Divide by 2

2y/2 = -5x/2 +3/2

y = -5/2 x +3/2

Use the Associative Property of Addition to write an expression equivalent to r+ (h+t). r+ (h+t) = Enter your answer in the answ
svlad2 [7]

Answer:

Associative propertry of addition.

Step-by-step explanation:

The associative property of addition states that:

a+(b+c) = (a+b)+c

It states that we can add numbers regardless of the groups. The sum does not change  irrespective of how the addends are grouped.

We are given the expression:

r + (h + t)

It can be written as:

(r+h) + t

It can also be written as:

r + (h+t) = (r+t) + h = (h+t)+r = h + (t+r)

Whatever maybe the arrangement of r, h and t, their sum will always be equal. We can regroup them in many ways but the sum remains the same.

Step-by-step explanation:

2*4+2/2=<em>9</em>

9*4+9/2=<em>40.5</em>

40.5*4+40.5/2=<em>182.25</em>

182.25 * 4 + 182.25/2 = 820.125
