Since you get "approximately 8 dollars per tip' the answer will be "about" (whatever x is ) deliveries

Okay that makes sense.

Thanks. Your goy here can't do maths to save himself

Everyone has strengths and weaknesses. This one's pretty basic though. I used Kahn Academy alot in college when I had a foreign teacher who didn't explain things in an articulate manner.

I'm in a learning support math class since my ACT score wasn't high enough to be eligible for me to enroll in the primary math course required for my major.

So I have to take this class and then college algebra class and then hopefully I'm done

Kahn's really good if you prefer to learn with videos

52(base pay) + 8x(tips per delivery >or= to 220

8x >or= 168

x >or= 168/8 = 21 deliveries

At least 21 deliveries in a day

>she

Nice try Schlomo

Making women deliver stuff...sad

220-52=168

168/8=21

21 deliveries

She must live in Texas where tipped pay is $.38/hr or something

Anyone who has taken a class in Differential Equations, could you confirm if the answer in green makes sense?

This section is on series solutions for linear equations

@ButMomShesA300YearOldLoliVampire yes the way you solved it up to the green circle is correct. Now the question asks for you to find two linearly independent solutions. In the green circle you see that after you specify `C_0` and `C_1` that all the other coefficients of a solution are determined. So for one solution choose `C_0 = 1` and `C_1 = 0`, and for the other solution choose `C_0 = 0` and `C_1 = 1`. These solutions are linearly independent since no scalar multiple times the `C_0` and `C_1` of one solution will ever give you the `C_0` and `C_1` of the other solution.

@ThisIsChris Thanks a ton!

@ButMomShesA300YearOldLoliVampire you're welcome!

Working on graphing linear equations in two variables (x and y).

And the line I have to graph is 5y=9

I put it in a graphing calculator and came back with a straight line (0,0) which is incorrect as the problem is asking for two coordinates for x and y

If theres no x in the equation it will be a straight line. Y = 9/5

@Warren H To add to @Deleted User 's response, you can rewrite `y = 9/5` as `y = 0x + 9/5`. Remember line formula is `y = (slope of line)x + (y-intercept)`. So for @Deleted User 's formula you have a slope of zero (i.e. a flat line) and a y-intercept of 9/5.

So the answer I came back with is 0, 1.8

But the computer program I have to do my homework on requires me to answer the x coordinate and it will not accept 0. Very weird

@Warren H hmm, how exactly is the question phrased? Do you have a screenshot?

Oh you need to enter something for B as well, any other point on the line will do. (They say enter two points because two points determine a straight line). You can enter any other point from the line, for example (1, 1.8)

Ohhh okay. That seemed to have worked. Is this the case whenever there is a straight line?

@Warren H yep!

This program drives me nuts

I just got another answer wrong for writing it in decimal numbers but it was counted as wrong because the answer was in fractions. Did the math calculation, and the fractions converted into the decimal coordinates that I entered.

Do you have a screenshot? I wonder if there's something specific in their question phrasing that indicates they want fractions instead of decimals.

It did not. It just said "Find the y-intercept and x-intercept of the following linear equation."

That's so weird, so for the y-intercept, they rejected 7.5 as the y-intercept? That's so weird because *they* give you the equation in decimal!
