Question 1133589: Sergio runs a bakery that sells two kinds of desserts. Sergio knows the bakery must make at least 29 and at most 48 batches of the White Chocolate Blizzards. The bakery must also make between 6 and 36 batches of the Nutty Squirrels. The batches of White Chocolate Blizzards take 9 ounces of flour, while batches of Nutty Squirrels require 16 ounces of flour. The bakery only has 864 ounces of flour available. If batches of White Chocolate Blizzards generate $1.75 in income, and batches of Nutty Squirrels generate $1.73, how many batches of the desserts should Sergio have the bakery make to get the most income?
How do I set up this up? I believe it is a linear program question. I have tried 29x+48y=9, 6x+36y=16 and the z function of z=1.75x+1.73y
I believe it's wrong since I am getting decimals as an answer...
Please help thank you...

Question 1133786: Hi. For homework I have to see if these two equations are perpendicular, parallel, or neither:
x=5 and 2x- 3 =25.
I don't understand because in the first one the y-intercept is given, but in the second there is no y.

Question 1134105: Write the point slope form of the equation of the line with the given properties.
Through (2, 3), slope is undefined
I do not know the set up of undefined. If someone could lay out the problem with the y=mx+b I would greatly appreciate it.
Thank you.

Question 1134089: Write the point slope form of the equation of the line with the given properties:
Through (-1,-5), slope =9
If someone could just lay it out simply I would be able to understand it. My text does not show a layout, therefore I am confused.
Thank you,

Question 1134401: 6. (20 pts) Josh wants to purchase custom-made refrigerator magnets to advertise his business. Two companies offer different deals:
Company A: Pay a design fee of $42.00, plus $4.80 per magnet
or Company B: Pay a design fee of $90.00, plus $4.20 per magnet
a. State a linear function f (x) that represents Company A's total charge for an order of x magnets.
b. State a linear function g(x) that represents Company B's total charge for an order of x magnets.
c. Josh wants to purchase 150 custom-made magnets, as cheaply as possible. With which company should he place his order? Show work/explanation.
d. For what number of magnets is the total charge exactly the same for both companies? Show algebraic work/explanation.
e. Fill in the blanks:
Company A is the cheaper option if ________(choose less or more) than ______ (enter number) magnets are ordered.

Question 1134451: I have been given this math riddle and it is worth some points, but I am confused how to go about answering it. Can anyone please help? Thank you in advance for your time.
Set up and solve word problems.
This one will require a bit of abstract thinking.
Let's consider a linear equation in standard form: ax + by = c,
where a, b, & c are real numbers.
For what values of a, b, and c:
(a) will the equation ax + by = c, have a positive slope,
(b) will the equation ax + by = c, have a negative slope,
(c) will the equation ax + by = c, have a zero slope,
(d) will the equation ax + by = c, have an undefined slope,
(e) will the equation ax + by = c, have a positive intercept,
(f) will the equation ax + by = c, have a negative intercept,
(g) will the equation ax + by = c, have a zero intercept; means the line goes through the origin.
This should be interesting in that this concept check is actually checking a "concept" rather than an answer to a specific problem.
