## anonymous 3 years ago The zoomster function, z(q)=4q+1/2, is used in space flight engineering. If, for some number "u", z(u+1/2)=1/2, then what is the value of "u"?

1. anonymous

$$z(q)=4q+\frac12$$If we're given that $$z(u+\frac12)=\frac12$$, we can rewrite the left-hand side by substituting in $$q=u+\frac12$$ into $$z(q)=4q+\frac12$$:$$4\left(u+\frac12\right)+\frac12=\frac12$$ Do you know what to do now?

2. anonymous

solve for u. i got -1/2

3. anonymous

Indeed, $$u=-\frac12$$.

thnx, bro!
