If you mean: y = -15x-4 then the slope is -15 and the y intercept is -4
If: 15x = 360 then x equals 360/15 = 24
--x + 15 = x + 15
It is: 15x
5x +12 = -78 -10x +10x +10x 15x +12 = -78 -12 -12 15x = -66 /15 /15 x = 4.4
The distributive property states that a(b + c) = ab + ac. This only works in your case if you meant to write 15(x + 20). That would equal 15x + 300.
When X = 4, 15X = 15 * X = 15 * 4 = 60
15x
It is 15x.
15x
The product of 15 and x is 15x. If you then want to substitute a numerical value for x to evaluate the expression of 15x when x equals that number then just multiply. For example, if x = 3, then 15x = 15(3) = 45 if x = 10, then 15x = 15(10) = 150 Good luck! :-)
If you mean: y = -15x-4 then the slope is -15 and the y intercept is -4

--x + 15 = x + 15
Given: 15x - 20y = -1 15y = 2 + 5x Then: 15x -20(2 + 5x)/15 = -1 ∴15x -40/15 - 100x/15 = -15/15 ∴225x/15 - 100x/15 = 40/15 - 15/15 ∴125x = 25 ∴x = 1/5 Check: 15(1/5) - 20(1/5) = -1 ∴3 - 4 = -1 ∴-1 = -1
15x - 15 = 10 Therefore, 15x = 25 Therefore, x = 25/15 x = 1.6 recurring (that is, 1.6666...)
If x>1 then the gcf is 15x. If x<1 then the gcf is 15.
