2014年5月12日 · 12x 4 +10x 3-12x 2 First, let see if the terms all have a common factor. All three have 2x 2 as a factor.

2019年6月11日 · Problem #1: 2y < -12x + 4y . 1) subtract 4y from both sides to get: -2y < -12x. 2) divide both sides by -2 (note that when you divide or multiply by a negative number in an inequality you MUST switch the sign): y > 6x. 3) Graph this boundary line and shade the appropriate side (in this case above the line because y is greater than the line (6x):

2017年3月24日 · If z = (12x^4)/y and both the values of x and y are doubled, we could write the new problem like this: z = [12(2x)^4]/2y Simplify the exponent part z = [12(16x^4)]/2y Simplify the numerator

Dndndn B. asked • 11/10/20 Find the equation of a line perpendicular to y=−12x −4 and passes through the point (3, 3)

2020年12月15日 · -4 = (-1/12)(-7) + b. b = -4 - 7/12 = -55/12. y = -x/12 - 55/12. However, the original equation y=12x+9 is apparently a typo or misprint. It should have been. y=(1/2)x +9, then the perpendicular line will have slope =-2. and the equation is. y=-2x + b. plug in the point (-7,-4) to solve for b-4 = -2(-7) + b. b = -18, which is the y intercept

2015年12月4日 · Find the minimum or maximum y-value for f(x) = 3x^2 + 12x + 4. Tell me whether it is a minimum (MIN) or maximum (MAX), then type a comma, then tell me the value. For example, if you find a minimum value of -40, you would type: MIN,-40

2019年4月17日 · f'(x) = 60x 4 + 120x 3 - 48x 2 and factor to get 12x 2 (5x 2 + 10x - 4) Set it equal to zero to get critical points meaning x = 0 and (using the quadratic formula), x = -1 + 3√5/5 and x = -1 - 3√5/5. Butting these in order, left to right we get A = -1 - 3√5/5, B = 0, C = -1 + 3√5/5
