The region describes a rectangle. F(x,y) is optimized at the intersecting points around the rectangle.
You can try plugging in (-3,-5) , (-3,4), (4,4) , (4,-5) and see which one gives you the largest value.
The max value of f(x,y) is at point (4,-5)
---> 4(4) - 7(-5) = 16 + 35 = 51
Answer:
sum of twice a number and three is 21
2x + 3 = 21
x = 9
Answer:
I believe its c.
Step-by-step explanation:
There using the equation mx+b=y. M is the slope(4), b is the y intercept (3).
The correct answer is the first option, which is:
(–7 + i) + 7i = –7 + (i + 7i)
The explanation is shown below:
1. By definition, in the associate property of addition you summ the number by grouping them with parenthesis, without matter where you use those parenthesis.
2. Therefore, as you can see, you can obtain the result of the addition by agruping the numbers <span>(–7 + i) + 7i or –7 + (i + 7i)</span> .
Step 01:
Game show
Data:
$2300 computer system
$5400 luxury vacation
$8700 boat
Step 02:
Expected winnings
p (luxury vacation) = 0.20
p (boat) = 0.15

E (game show) = $1080 + $1305 = $2385
The answer is:
The expected winnings are $2385
