Answer:

X = 5/2

Step-by-step explanation:

I will assume that you meant (1/5)X + 1/2 = 1. The LCD is 10.

Multiplying both sides by 10, we get:

2X + 5 = 10, or 2X = 5, or X = 5/2

x = $\frac{In (2) + In (3)}{In (2) - In (3)}$

Or

x ≈ - 4.41902258

Y= 2x-1 is a tangent to y=x^2. Name the point of tangency,

lubasha [3.4K]

Answer:

Point of tangency is $x=1$ or $(1,1)$

Step-by-step explanation:

You don't really need to use Calculus here. You can just set each equation to each other and solve for x (the point of tangency):

$x^2=2x-1$

$x^2-2x+1=0$

$(x-1)(x-1)=0$

$x=1$

Therefore, the point of tangency is $x=1$ or $(1,1)$
