Answer:

no solution

Step-by-step explanation:

12x - 42 - 3 = 12x - 21

12x - 45 = 12x - 21

Answer:

No solution

Step-by-step explanation:

6(2x - 7) - 3 = 12x - 21

First, you have to use the distributive property on the left side.

12x - 42 - 3 = 12x - 21

You will have to add like terms on the left side.

12x - 45 = 12x - 21

Now you can subtract 12x (from either side) from both sides.

12x - 45 - 12x = 12x - 21 - 12x

-45 = -21

-45 is not equal to -21, therefore, there is no solution, or the euqation is not true.

Find the values of m for which the lines y=mx-2 are tangents to the curve with equation y=x^2-4x+2
deff fn [24]

Let y= mx-2 be the tangent line to y=x^2-4x+2 at x=a.

Then slope, m=\frac{dy}{dx} at x=a = 2a-4.

Hence the equation is y=(2a-4)x-2

Let's find y-coordinate at x=a using tangent line and curve.

Using tangent line y at x=a is (2a-4) a -2 =2a^{2}-4a-2

Using given curve y-coordinate at x=a is a^{2}-4a+2

Let's equate these 2 y-coordinates,

 2a^{2} -4a-2 = a^{2} -4a+2

2a^{2}-a^{2} = 2+2

a^{2}=4

a=2 or -2.

If a=2, m=2a-4 = 2*2-4=0

If a=-2,m= 2(-2)-4 = -8

Hence m values are 0 and -8.
