Determine if the plane given by -x + 2z = 10 and the line given by r = (5,2-t,10+4t) are orthogonal, parallel

Determine if the plane given by -x + 2z = 10 and the line given by r = (5,2-t,10+4t) are orthogonal, parallel or neither.-Notice that you can write the equation of the plane as: -x + 0y + 2z = 10. At

Please help! Struggling with these Algebra questions!!

The width of a rectangle is 1ft less than the length. The area is 2ft^2 Find the length and the width. Find the x and y intercepts f(x)= -x^2+2x+63 Find the x and y coordinate of the vertex, line o

How do you answer these two math problems

OK here are the problems 102=p-(-130) and this one too 27=h+(-8)-hmmmm...an oceana heath question.lets see... 102=p-(-130)well, just add a negative 130 to both sides and... -28=p or p = -28 27=h+(

How do you solve this log equation

3xe^-x + x^2e^-x = 0-First of all, this is an exponential equation, not a logarithmic one. 3xe^(-x) + x^2 e^(-x) = 0 e^(-x) (3x + x^2) = 0 e^(-x) ≠ 0, so x(3 + x) = 0 x = 0 or x = -3-3xe^(-x) + x^2*e

How would i solve bx+a=dx+c for x

algebra 2, strugglin. haha-Subtract bx on both sides so the equation is a=dx+c-bx. Then subtract c on both sides so you get a-c=dx-bx. Factor out the x on the right side making a-c=x(d-b). Then divi
