Write The equation 3X +2 equals 4X to the second power in standard form

1 answer:

5 0

3x+2=4x^2 would turn into -4x^(2)+3x+2=0 If you want X you would need to use x=3+- sqrt (41) divided by 8.

There you go hoped I helped. :)

(a) Find the slope of the curve y= x^2 - 2x - 3 at the point P(2, -3) by finding the limit of the secant slopes through point

gayaneshka [121]

Answer:

Step-by-step explanation:

P=(2,-3)

Q=(a,a²-2a-3)

$\Delta y=a^2-2a-3-(-3)=a^2-2a\\\Delta x=a-2\\\\\displaystyle \lim_{a \to 2} \dfrac{a^2-2a-3-(-3)}{a-2} \\\\=\lim_{a \to 2} \dfrac{a^2-2a}{a-2} \\\\=\lim_{a \to 2} \dfrac{a(a-2)}{a-2} \\\\=\lim_{a \to 2} \dfrac{a}{1} \\\\=\lim_{a \to 2} a \\\\=2\\$

Proof:

y'=(x²-2x-3)'=2x-2

y'(2)=2*2-2=2

You square root both sides. And it would be a=0.8
