What is the solution to this system of linear equations? 2x + y = 1
3x - y = -6
O -1.3)
O (1.-1)
O (2, 3)
(5.0)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

d.) yes, because the volume of the cone is greater than the volume of the sphere
