Answer:
Inequality to represent given data is y ≥ 5.
No, y = 4 is not a solution, since 4 is not a value that falls within the domain of the solutions for the inequality.
Step-by-step explanation:
Enter an inequality that represents the phrase the sum of 1 and y is greater than or equal to 6. The inequality is y = 4 a solution.
i) therefore y + 1 ≥ 6
ii) therefore y ≥ 5
iii) No, y = 4 is not a solution, since 4 is not a value that falls within the domain of the solutions for the inequality.
Answer: A. You got it! ✔
Step-by-step explanation: All of the others use the "Y" Axis. That's big no-no for this question. Enjoy :)
Answer:
y = 2(x-3)^2 - 2
Step-by-step explanation:
y = 2x^2 - 12x + 16
y = 2(x^2 - 6x + 8)
y = 2(x^2 - 6x +8 +1 -1) you "complete the square" by bringing the last term (8) up to "half of the middle co-efficient squared". Middle co-efficient is -6, half is -3, squared is 9. To get from 8 to 9 you must add 1 (+1), but if you add 1 you must subtract 1 (-1) so that you don't change the overall value of inside the bracket
y = 2(x^2 - 6x +9) - 2 (bring the -1 outside of the brackets)
y = 2(x-3)^2 - 2
Answer:
The number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas
Step-by-step explanation:
Given
Size of Gas = 12 gallon of gas
Distance = 456 miles
Calculating the number of miles her car travel per gallon of gas.
This in calculated by distance/size of gas
By substituton, it becomes
Number of miles = 456 miles/12 gallons ------ divide
Number of miles = 38 miles / gallon.
Hence, the number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas
