We Do! Carter got $60 in cash for his birthday. He decides to spend it on apps for his iPad. Each
app costs $2. Write an equation that represents the money he has left after buying *
amount of apps.
Question: Write a linear equation for the following information.
Step 1: Find the slope: Look for words like "per," or "each."
**If the question asks for total cost, it's positive. If it's asking for how much is left, then it's negative.
Step 2: Find the y-intercept: Remember that the y-intercept are initial values, what you started off with.
Step 3: Put it together in the form of y= mx + b

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

you,

mrb

(a + b) (a^2 - a b + b^2)

im guessing (23,14). hope this : )
