Need asap question in the picture

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.

Rewrite the expression in z to the n power. the expression i was given is: 1 over z to the negative 1 half power.
