Which method would you choose to solve the following system of equations? Solve it.y=2x+1 (1)3x+y=7 ​ (2)

Solve the system by eliminationx+y+2z=23x+4y-z=254x-y+3z=-7

In this problem, you are given 7x-4=20x+2. How do you solve for x?

Solve by completing the square 5𝑥2 − 4𝑥 + 2 = 0

I have no idea what to do here. If g(x) = 5x2+7 and f(x)= x2+1, then what is g(f(x)) and f(g(x))? What is the value of both equations if x =2?

I have been given a system of differential equations but I'm not quite sure how to determine whether it is homogeneous or non homogeneous.The system is:dx/dt= 8sin(t)x + ln(t)y;dy/dt= (4t^2)y +... more

For the limit lim x-->2 (x^3 - 3x + 4) = 6 find the values of δ that correspond to ε = 0.2 and ε = 0.1

f(x) = (1/√(2Π)) e–(x–c)^(2)/(2b^(2))  what is maximum and what if inflection point?

I need help i am so confused

You make a new hat by rotating the curve f(x)=1/64X^7 +1/32X^5+3/8X^3-3/4X^2-2X+2   -1<= x <=2 around the line x=-1. Calculate the surface area of new hat.

f(x) = sqrt(x) a = 4, n = 2, 4 ≤ x ≤ 4.5   Use Taylor's Inequality to estimate the accuracy of the approximation f(x) ≈ Tn(x) when x lies in the given interval.     R(2)(x) <=

r(t) = < e5tcos(12t), e5tsin(12t), e5t >1. Verify directly that a(t) (dot) B=0   2. What happens as t-> infinity and t-> -infinity  for the curvature and torsion
