Step-by-step explanation:
The system would be:
And I attached the graph. The system will have 2 solution (The 2 intercepts between the curves)
Answer:
|x-3|+4 = 12
|x-3| = 12-4
|x-3| = 8
now solve for both positive and negative values
x - 3 = 8 | x - 3 = -8
x = 8 + 3 | x = - 8 + 3
x = 11 | x = -5
solution set : { 11, -5 }
Step-by-step explanation:
Year 1: 7lbs x 3years= 21lbs
Year 2: 21lbs x 3years = 63lbs
Well see here that it practically gives us the answer. The submarine rises 4.3 meter each minute of the first 15 minutes. Multiplying these two given numbers you get 64.5 . Great we're halfway through. Now onto the second equation. 5.2 times 12 . easy right? The answer round to 62.4 . Now all that's left to do is add the two together. After the 27 minutes the submarine should be at an elevation of 126.9 feet. rounding to 127 if you teacher requires you to round the numbers.
Answer:
Step-by-step explanation:
Slope = (-6-9)/(-1-4) = -15/-5 = 3
