Hi, can I have some help with these math questions, please?

4 Sketch the region enclosed by the curve and compute the area given by y = 8 - 1x , y v x and x = 0 128 * + y = 4 x-4 70 and y = 3x+4. (8 ) 5 Find the area of the enclosed region bounded by X = 1 , 1= - 2 x + 10, y =ex and y - 9 (17. 657) Determine the area of the region bounded by the given set of curves 1 ) 4= x x z + 1 , y = e 2, * = 3 and the y-axis ( 17 17) 1 1 1 =1 4 = ( x+2 )2 x - 3 and x = / (7 96) 4 X+21 2 x=exe y =2 and 4=1!
