Answer:
Step-by-step explanation:
so these two lines cross at some point.. and they want to know the y point at which they cross... sooo..
solve them as a system to find the points that are common to both
Eq. 1) 5x -2y = 16
Eq. 2) -4x+6y=-15
i'll use the elimination method as these equations "lend" themselves to that way.. they are easy to solve that way .. in other words..
multiply Eq. 1 by 3 the add Eq. 2 .. to it... add the terms as columns....
15x-6y = 48
<u> + ( -4x+6y=-15)</u>
= 11x+ 0y =33
x=3
nice, now plug 3 in for x in one of the Eq. try Eq. 1
5(3)-2y=16
15-2y=16
-2y =1
y = 
since we're looking for the y coordinate... that's your answer
Answer:
The population of 75 hours from now would be 40,000.
Step-by-step explanation:
The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.

Answer:
Divide both sides by 3
∣x−1∣≥12/3
Simplify 12/3 to 4
∣x−1∣≥4
Break down problem into 2 equations
x−1≥4
(x−1)≥4
Then solve...
ANSWERS:
x≥5
x≤-3
