What is the x-intercept of the line with this equation 8x−13y=16? Enter your answer in the box.

(
, 0)

(2, 0 )

Step-by-step explanation:

The y- coordinate of any point on the x- axis is zero.

Substitute y = 0 into the equation and solve for x

8x - 13(0) = 16

8x - 0 = 16

8x = 16 ( divide both sides by 8 )

x = 2

The coordinates of the x- intercept are (2, 0 )

hello from mrbilldoesmath!

answer:

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

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

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

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
