6. Write an equation of a line parallel to y = 3x + 9 and goes through the point (-1,5).

lisabon 2012 [21]

Answer: The equation parallel to the line is y=3x+8

Step-by-step explanation: Parallel lines have the same gradients, wr have a gradient for the above line which 3. The standard formula for the linear equation is y=mx+c

We have to calculate c since we have x and y.

y=mx+c

5= 3(-1)+c

c=8

The equation become y=3x+8

If xy + y² = 6, then the value of dy/dx at x= -1 is<br>

mylen [45]

Hi there!

$\large\boxed{\text{At (-1, -2), }\frac{dy}{dx} = -\frac{2}{5}}}$

$\large\boxed{\text{At (-1, 3), }\frac{dy}{dx} = -\frac{3}{5}}}$

We can calculate dy/dx using implicit differentiation:

xy + y² = 6

Differentiate both sides. Remember to use the Product Rule for the "xy" term:

(1)y + x(dy/dx) + 2y(dy/dx) = 0

Move y to the opposite side:

x(dy/dx) + 2y(dy/dx) = -y

Factor out dy/dx:

dy/dx(x + 2y) = -y

Divide both sides by x + 2y:

dy/dx = -y/x + 2y

We need both x and y to find dy/dx, so plug in the given value of x into the original equation:

-1(y) + y² = 6

-y + y² = 6

y² - y - 6 = 0

(y - 3)(y + 2) = 0

Thus, y = -2 and 3.

We can calculate dy/dx at each point:

At y = -2: dy/dx = -(-2) / -1+ 2(-2) = -2/5.

At y = 3: dy/dx = -(3) / -1 + 2(3) = -3/5.

What is a / b (2x - 12) = c / d ; x ?

Alex17521 [72]

we are given

$\frac{a}{b} (2x-12)=\frac{c}{d}$

we can solve for x

We can isolate x

step-1: Multiply both sides by b/a

$\frac{b}{a}*\frac{a}{b} (2x-12)=\frac{b}{a}*\frac{c}{d}$

$(2x-12)=\frac{bc}{ad}$

step-2:Add 12 both sides

$(2x-12)+12=\frac{bc}{ad}+12$

$2x=\frac{bc}{ad}+12$

step-3: combine right side

$2x=\frac{bc+12ad}{ad}$

step-4:Divide both sides by 2

$x=\frac{bc+12ad}{2ad}$ ..............Answer
