What is the solution to the following system?

3x+2y+z=20
x-4y-z=-10
2x+y+2z=15

a. (2, 3, 4)
b. (4, 3, –2)
c. (4, 3, 2)
d. (6, 7, –2)

Scale factor of 2 is used to enlarge a figure as shown below the area of is 18 in.²

For which pair of functions is (gof)(a)=|a|-2?

Suppose you are going to graph the data in the table. minutes temperature (°c) 0 -2 1 1 2 3 3 4 4 5 5 -4 6 2 7 -3 what data should be represented on each axis, and what should the axis increments be? x-axis: minutes in increments of 1; y-axis: temperature in increments of 5 x-axis: temperature in increments of 5; y-axis: minutes in increments of 1 x-axis: minutes in increments of 1; y-axis: temperature in increments of 1 x-axis: temperature in increments of 1; y-axis: minutes in increments of 5
