Understand subtraction of rational numbers as adding the additive inverse, p - q = p + (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
Answer:
<em>(18 , - 10) </em>
Step-by-step explanation:
5x + 4y = 50 .... <em>(1)</em>
x + 2y = - 2 ... <em>(2)</em>
Solve (2) for "x"
x = - 2y - 2 .... <em>(3)</em>
(3) ----> (1)
5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ <u><em>y = - 10</em></u> .... <em>(4) </em>
(4) ----> (2)
x + 2(- 10) = - 2 ⇒<u><em> x = 18</em></u>
<em>(18, - 10)</em>
Formula for <span>area of a pentagon </span>is A = (5/2)la
where l is the length of a side and a is the length of an apothem Putting the value of l and a in equation:
A = (5/2)(3)(k) = 15/2 k = 7.5k
Answer:
see below
Step-by-step explanation:
If we let X represent the number of bagels produced, and Y the number of croissants, then we want ...
(a) Max Profit = 20X +30Y
(b) Subject to ...
6X +3Y ≤ 6600 . . . . . . available flour
X + Y ≤ 1400 . . . . . . . . available yeast
2X +4Y ≤ 4800 . . . . . . available sugar
_____
Production of 400 bagels and 1000 croissants will produce a maximum profit of $380.
__
In the attached graph, we have shaded the areas that are NOT part of the solution set. (X and Y less than 0 are also not part of the solution set, but are left unshaded.) This approach can sometimes make the solution space easier to understand, since it is white.
The vertex of the solution space that moves the profit function farthest from the origin is the one we are seeking. The point that does that is (X, Y) = (400, 1000).
