Ok so you need to find the x and y- intercepts. to do this you simply plug 0 in for x and then for y, giving you the value of each variable.

15x + 20y = 1,800

15x + 20(0) = 1,800
15x = 1,800
x = 120

15(0) + 20y = 1,800 
20y = 1,800
y = 90

your x-intercept is (120,0)
your y-intercept is (0,90)

First you need to get the equation into y - intercept form in order to graph it. The equation needs to be in the form y=mx+b. do you know how to convert that equation to y=mx+b?

How do you factor 9x^3 + 64 <br> (Please show steps)
Novosadov [1.4K]

First, let's review the formula for the "sum of two cubes:"

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

Unfortunately, 9 is not a perfect cube. The cube root of 9 is 9^(1/3), and the square of the cube root of 9 is therefore 9^(2/3).

Thus,

9x^3 + 64 = (9^(1/3)*x + 4) * (9^(2/3)x^2 - 4*9^(1/3) + 16)

A company that builds homes advertises that by choosing from its upgrade options each of its new homes is available In 256 diffe
lutik1710 [3]

Solution:

Let number of upgrade options = p

Let total number of distinct variations in which 256 new homes is available = k

So, p × p× p.....k times = 256

⇒p^k= 256

256= 2  × 2 ×2 ×2 ×2 ×2 ×2 ×2= 2^6

256= 4  ×4  ×4  × 4=4^4

So,Either, number of upgrade options = 2 ,

Or , Number of upgrade options = 4
