The answers are -1+ square root of 7 and -1- square root of 7. In other words the answers are options B and D.
Hope this helps ;)
The first number: x
The second number: x + 3
The third number 2 * x - 11
Sum of all numbers: 65
We can write it down as an equation:
65 = x + 3 + x + 2x - 11
65 = 4x + 3 - 11
65 = 4x - 8 / + 8 (both sides)
73 = 4x / ÷ 6 (both sides_
x = 18,25
Doublecheck:
The first number: 18,25
The second number 18,25 + 3 = 21,25
The third number: 2 * 18,25 - 11 = 36,5 - 11 = 25,5
Sum of all numbers: 18,25 + 21,25 + 25,25 = 65, so it's correct :)
Answer:
Domain: {-3, 0, 2, 4, 5)
Range: {1, 2, 3, 7}
The relation is a function because for every x-value there is one y-value. In other words, for every input there is one output.
Answer:
well 278 rounded to the nearest 10 is 280 idk how to round a whole number to the nearest 10th
F + V = E + 2
F = 25
V = 17
25 + 17 = E + 2
42 = E + 2
42 - 2 = E
40 = E <== there are 40 edges
