(0,-7)
-7=11(0)+4
-7=0+4
-7 is not 4 -----not a solution
(-1,-7)
-7=11(-1)+4
-7=-11+4
-7=-7 ----solution
(1,-7)
-7=11(1)+4
-7=11+4
-7=15
-7 is not 15 ----not a solution
(2,26)
26=11(2)+4
26=22+4
26=26 ----soltion
(-1, -7) & (2, 26) are solutions to the equation
In scientific notation, you want (a number less than 10 and more than 0) times 10^x
so 48978 made so that it is less than 10 and more than 0 is
4.8978
we count how many times we divided 48978 by 10 to get 4.8978 and we get 4
so 4.8978 times 10^4
or on an online test
4.8978e+04
Answer:
Step-by-step explanation:
At least means greater than or equal to, so that is the symbol we will use. Now, we want the inequality to compare the distance she plans to jog and the amount of time jogged multiplied by the speed, since time times speed equals distance.
Writing this out we get 1.5 ≤ 3.75x
so 1.5 will always be less than or equal to the distance jogged. let me know if there is something you don't understand. But after this just solve for x.
