Ill give u brainliest! for the equation y=7x-2, what is the rate of change? what does it mean? explain how u got ur answer plz

Step-by-step explanation:

The rate of change is 7. rate of change is the slope. According to Google, "Rate of Change Formula helps us to calculate the slope of a line if the coordinates of the points on the line are given. The slope of the equation is also called as rate of change of the equation. The term 'rate of change' refers to the slope of the line that connects the two points of the line. "

To get the rate of change, "the vertical change divided by the horizontal change between two points on a line. We can find the slope of a line on a graph by counting off the rise and the run between two points. If a line rises 4 units for every 1 unit that it runs, the slope is 4 divided by 1, or 4. "

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)

using pemdas, (order of operations) you'll see the answer is 24.
