Writing two step expressions and equations. 19. six less than twice a number x is four
20. four more than the product of 2 and a
21. Nine times a number decreased by four
22. two less than the quotient of 15 and a number
23. five times the sum of six and some number
24. the quotient of 7my and d decreased by 9
25.twice the difference of y and three
26. the difference of 9 and the quotient of s and -4
27. the sum of 5 and product of 7 and x
28. three more than quotient of 5 and a
29. the product of 4 and the difference of x and 3
30. the product of the difference of x and 3 and 4

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

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.
