What is the ordered pair for 2y equals 4x-16 and 5y equals 4x plus 8?
2y = 4x - 16 5y = 4x + 8 Subtract the first equation from the second: 3y = 24 so that y = 8 Substitute this into the first equation: 16 = 4x - 16 ie 32 = 4x so that x = 8 So the solution is (8, 8)
4x plus 5y 40?
If you mean: 4x+5y = 40 then y = -0.8x+8 whereas as -0.8 is the slope and 8 is the y intercept of a straight line equation
-20x 5y equals 40 changed to slope-intercept form?
Oh, dude, you just gotta rearrange that equation a bit. So, like, first divide by 5 to get -4x - y = 8. Then, if you wanna be all fancy and use slope-intercept form, just solve for y to get y = -4x + 8. And there you have it, a technically correct answer with a sprinkle of my signature humor.
5y plus 8 equals 7y-6?
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7
What is 4x plus -12 equals 8?
If: 4x+(-12) = 8 then 4x = 20 and x = 5
