What the person above said. when you multiply 6(x+5) out, you will get 6x+30. you will get the same for all of the other choices except for the 2nd one, but 6(x+5) is the one that is factored out the most, so this would be the best choice. if you need anymore help, let me know!
On a cartesian plane, the -intercept of a function is the point where the graph of that function intersects with the -axis.
The -axis of a cartesian plane is the same as the equation (that is, the collection of all points with an -coordinate of .)
Construct a system of two equations, with one equation representing -axis and to represent the graph of this function:
.
Solve this system for and for . If a solution exists, then the -axis and the graph of would indeed intersect. The point would be the intersection of the -axis and the graph of .
Substitute the second equation of the system into the first.
.
Hence, the intersection of the -axis and the graph of would be . By definition, this point would be the -intercept of .
