if x equals -1, then find the matching value for y
9x+2y=-5

2-digit numbers less than 91 which are 1 less than a multiple of 10

Consider the integral: 4 0 16 − y2 − 16 − y2 4 1 x2 + y2 dz dx dy . (a) describe w. use the standard view of the x, y, and z axes. front half of a cone with a rounded top. full cone with a flat top. right half of a cone with a flat top. front half of a cone with a flat top. right half of a cone with a rounded top.

I'll give brainliest if you answer right : )
