The |x| operator means 'absolute value' or the positive value of the negative values. To help this make sense, here's a visual representation:

But,

Do you see what I mean? BTW, your answer will just be 8 + 8 or 16.
Answer:
C
Step-by-step explanation:
The range is the values of y from the vertex upwards
The vertex = (- 2, - 4) → y = - 4
The range is from - 4 upwards in the direction of the parabola, that is
range is [ - 4, ∞ )
Answer:
The equation for area of a triangle is height multiplied by the base length, divided by 2. So, if the height is 2, and the base is 4, then you multiply the two together, making 8, and then divide it by 2, making the final area 4. So if the dimensions are doubled, then the equation would be 4 times 8 divided by 2. Which is 16. If we do this again with 16 times 8, we will get 128, which when divided by two is 64. This is 4 times 16, just as 16 is 4 times the original answer 4. This means that every time you double the dimensions you will get the original answer multiplied by 4.
Step-by-step explanation:
Hi There!
Change all the fractions to decimal you do that by dividing numerator by the denominator. Remember

as a decimal is 0.5
A=

= 0.43
B=

= 0.60
C=

= 0.8
D=

= 0.42
E=

= 0.6
Based, on the data above B,C,E are greater than

because they all have decimals greater than 0.5, B= 0.6, C= 0.8, E=0.6
So,

are all greater than

Hope This Helps :)
Answer:
10 kph
Step-by-step explanation:
Find the speed of the current of the river.
20/(20 - c) + 180/(20 + c) = 8
20(20 + c) + 180(20 - c) = 8(400 - c^2)
8c^2 - 160c + 800 = 0
8(c^2 - 20c + 100) = 0
8(c - 10)^2 = 0
c = 10
The speed of the current of the river is 10 km/hour.
