If y equals 3x and 3x equals 12 then what does y equals?
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
What is an equation in slope intercept for 6x plus y equals 12?
standard form (slope-intercept) is y = mx + b where m = slope and b = y intercept 6x + y = 12 subtract 6x from both sides y = -6x + 12 m = -6; b = 12
If y equals one-forth x and x equals -12 then what is y?
x equals -12 and y equals 1/4 of -12, so y = -3.
What is the slope of a line that's y equals 12x plus 1?
The equation is in standard form y = mx + b where m is the slope and b is the y-intercept. For y = 12x + 1, m = 12 so the slope is 12.
What is y equals y-my equals m plus y?
using normal algebraic methods, all I can get is m=0 and y=all numbers
What is the answer to 12 equals 24-y?
12 = 24-y then y = 12
If y equals 3x and 3x equals 12 what does y equal?
y = 12. It's the transitive property. y = 12 = 3x.
What are M and Y if Y plus y plus y plus equals MY?
M=3 because y+y+y= 3xY and MY= MxY
Answer for m equals 1 y-intercept equals 2?
-1
If y is directly proportional to x and y equals 12. What is the value of x when y equals 5?
Insufficient information. What is x when y = 12?
Y equals mx plus b solve for m?
y-b/x=m
