3x + 7y
7x + 7y
3x - y
3x + y
ErklärungGroup like terms: (5x - 2x) + (3y + 4y) = 3x + 7y.

ErklärungThe standard derivative of the sine function is the cosine function.
x^2 - 5x + 6 = 0
x^2 + 5x + 6 = 0
x^2 - 6x + 5 = 0
x^2 + 6x + 5 = 0
ErklärungA quadratic equation can be written as x^2 - (sum of roots)x + (product of roots) = 0.

ErklärungSince 2^5 = 32, log_2(32) is equal to 5.
3/4
-3/4
4/3
-4/3
ErklärungRearranging the equation to y = mx + c gives 4y = 3x + 7, or y = (3/4)x + 7/4. The slope m is 3/4.

-3/2
2/3
-3
ErklärungConverting to slope-intercept form y = mx + c, 2y = -3x + 6, so y = -1.5x + 3. The slope is -1.5 or -3/2.
