To write a verbal expression for (3x - 4), you can say "three times a number (x) minus four." This conveys the mathematical operations involved: multiplying the variable (x) by three and then subtracting four from the result.
" 3x + 5 " does.
3x - y = -4 3x - y = 0 Those lines do not intersect. They are parallel. You can demonstrate by solving either of them for one of the two variables, then plugging it's value into the other: 3x - y = -4 ∴y = 3x + 4 Now substitute: 3x - y = 0 ∴ 3x - (3x + 4) = 0 ∴ 3x - 3x - 4 = 0 ∴ -4 = 0 This result is obviously incorrect, indicating that the lines do not intersect.

3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
The thumbs-up gesture typically has a direct verbal translation, commonly meaning "okay" or "good job."
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
3x - y = 4 Get y by itself to see if it is the same as y = 3x - 4: 3x = 4 + y 3x - 4 = y Therefore, 3x - y = 4 is the equivalent of y = 3x - 4.
3x+4y = 17 -3x -3x 4y = -3x+17 Divide each TERM by 4 y = -3x + 17 4 4

3x+4y = 17 -3x -3x 4y = -3x+17 Divide each TERM by 4 y = -3x + 17 4 4
-3x+14 = -4 -3x = -4-14 -3x = -18 x = 6
