Solve the system u=2x-y v= 3 x+2y, for x and y in terms of u and v then find the value of Jacobian σ(x, y)/σ(u, v). Find the image under the transformation of the triangular region with the vertices (0,0) ,(2,4), and (2, -3) in the x, y plane. Sketch the transformed region in uv plane. The function for x in terms of u and v is x=?

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?

Asap! will mark brainliest! ( respond asap, it's urgent! : )) what is the slope for equation y =-3x + 8
