Answer:

Step-by-step explanation:

Number of pigs with John = x

Number of pigs with Taylor = x - 7

Number of pigs with Mark = 2x + 6

Total pigs = 459

x + x - 7 + 2x + 6 = 459

x+ x + 2x - 7 + 6 = 459

4x - 1 = 459

4x = 459 + 1

4x = 460

x = 460/4

x = 115

Number of pigs with John = 115

Number of pigs with Taylor = 115 - 7 = 108

Number of pigs with Mark = 2*115 + 6 = 230 + 6 = 236

Find the least common denominator x^4/x^2+2x+1 and -8/x^2+5x+4

Harman [31]

Answer:

(x + 4)(x + 1)(x + 1) or (x + 4)(x + 1)²

Step-by-step explanation:

Factor both denominators and see what you are missing between them

(x^4)/[(x + 1)(x + 1) -8/[x + 4)(x + 1)]

So in order to get a common denominator, we need

(x + 4)(x + 1)(x + 1) as a denominator, or (x +4)(x + 1)²

Determine which equation is parallel to the line JK and which is perpendicular to like JK

sattari [20]

Answer:

If the equation of JK is y = mx + c, then y = mx + c' is the equation of the straight line parallel to above and $y = - \frac{1}{m}x + b$ will be perpendicular to that.

Step-by-step explanation:

Let us assume that the line JK has the equation in slope-intercept form as

y = mx + c ............. (1)

Therefore, the equation has slope = m

Now, any straight line having an equation with slope m will be parallel to line JK.

So, the equation of the straight line which is parallel to equation (1) will be

y = mx + c', where, c' is any real constant.

Now, let us assume that another straight line having equation

y = nx + a is perpendicular to the line JK i.e. equation (1).

Now, we know if two lines are perpendicular to each other then the product of their slopes will be - 1.

So, mn = - 1

⇒ $n = - \frac{1}{m}$

Therefore, the equation of a straight line which is perpendicular to equation (1) will be $y = - \frac{1}{m}x + b$ where b is any real constant. (Answer)
