Answer:
C
Step-by-step explanation:
Option C is the only one that's linear because it follows all of the rules for a line to be linear. To check, use the process of elimination:
A). When x is an absolute value, the line will not be linear because an input will have two outputs.
B). x cannot be in the denominator of a fraction for the line to be linear
D). Once again, x cannot be an absolute value.
*Note: I'm assuming in option B, 7x is in the denominator and 1 is in the numerator. If the fraction is simply 1/7 multiplied by x, it is linear along with C.
Step-by-step explanation:
It is given that, three oil tankers together contain 37 5/7 litres of oil.
Total volume of oil is 
If two tankers have 11 3/14 litres and 12 3/7 litres of oil.
Oil in first tanker is 
Oil in second tanker is 
Oil in first and second tanker is :

Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )

Hence, this is the required solution.
x = 9
Step-by-step explanation:
5x - 15 + 2x = 4x + 12
7x - 4x = 12 + 15
3x = 27
x = 9
3000(0.25)=750
C is correct. Hope this helps!
You have 2x^2 + 9x -9 and 3x^2 -2x +14
To find total area add the two polynomials together by combining the like terms.
2x^2 + 3x^2 = 5x^2
9x + -2x = 9x-2x = 7x
-9 + 14 = 5
Total area = 5x^2 + 7x + 5
