Answer:
The second one. it's the only one that has a pattern for both sides. for every x value that goes up, the y-values goes down one. that function has a slope of -1
Step-by-step explanation:
I hope this helps :)
x^3y^3 + 343
The way the sum of cubes works is by taking the roots of each term and applying the formula.
The sum of cubes is as follows:
a^3 + b^3 = (a + b)(a^2 - ab + b^2)
In this case, we would display it like this:
x^3y^3 + 343 = (xy + 7)(x^2y^2 - 7xy + 49)
Answer:
yes
Step-by-step explanation:
16/7 = 2.28
80/35 = 2.28
4x + 7x = 33
11x = 33
x = 3
4x = 4(3) = 12
7x = 7(3) = 21
12 and 21 are how you split 33 in to a ratio of 4 to 7.
