Choose a system of equations with the same solution as the following system: 4x − 2y = 6
2x + y = 5

A) −4x − 2y = 10
2x − 3y = 21

B) 4x + 2y = 10
10x + y = 21

C) −4x − 5y = −1
2x − 6y = 10

D) 3x + 2y = 6
9x + y = 17

Which quadratic function best fits this data? x y 1 32 2 78 3 178 4 326 5 390 6 337 a. y=11.41x2+154.42x−143.9 b. y=−11.41x2+154.42x−143.9 c. y=11.41x2+154.42x+143.9 d. y=−11.41x2+154.42x+143.9

The fraction 7/9 is equivalent to a percent that is greater than 100%. truefalse

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
