What is the interval notation for the compound inequality?
−2
@Ultrilliam
(−2,9] http://prntscr.com/grdfof
can you help with some more dude?
Sure I can try
Solve for x. −9<4x+3≤27 Enter your answer, as one inequality,
@dude
\[-3<x\le \:6\] Do you want work?
no
Is the answer a single digit or an inequality?
inequality
\[x<-24\quad \mathrm{or}\quad \:x\ge \:6\]
alright
Top right option
http://prntscr.com/grdsfb I think this, I used (2,2) as a point of reference
Bottom left graph
Also bottom left
First option looks right
its more than one answer
Suzette ran and biked for a total of 34 mi in 3.5 h. Her average running speed was 6 mph and her average biking speed was 12.5 mph. Let x = total hours Suzette ran. Let y = total hours Suzette biked. Use substitution to solve for x and y. Show your work. Check your solution. (a) How many hours did Suzette run? (b) How many hours did she bike?
maybe just help me through this one
So I would assume you would write \[6x+12.5y=34\] and \[x+y=3.5\] you can use system of equations which you get 1.5 hours ran and 2 hours biked
