A polling firm determines that the percent of likely voters who support a certain mayoral candidate can be represented by a function P (t) where t is measured in weeks since the candidate entered the race. Suppose P (7) = 15.
(a) What does P ′(7) = 4 mean?
(b) If P′(7) = 4, what percent of likely voters do we expect to support this candidate 8 weeks
after she entered the race?

Part a : solve - vp + 40 < 65 for v . part b : solve 7w - 3r = 15 for r show your work!

Name the quadrilaterals that have four equal sides.

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
