I believe its the second one.......the last one is eliminated based on the y intercept......
plug the x and y into the equations and see which side equals.....
368 spaces now, why?
There are 22 spaces per row, and we know there are 8 rows, so thats 176 spaces last month,
we add 4 spaces to each row of 22, thats 26 spaces per row, 26 * 8 = 368 total spaces
Answer:
You will receive 601.2 Indian rupees.
Step-by-step explanation:
Because 62.4d-210 is the expression per dollar, and you are exchanging 13 dollars, you need to plug in 13 for d, because 13 is the number of dollars, and d represents the number of dollars.
62.4(13)-210 solve.
811.2-210
601.2 The answer is then 601.2
Hello from MrBillDoesMath!
Answer:
Case 1: x is a real number. In this case f(x) has no real solution.
Case 2: x is a complex number. In this case the roots of f(x) are
x = 3 +\- 2 sqrt(3) i
(sqrt = square root. "i" = sqrt(-1))
Discussion:
Add 1 to both sides of the given equation:
2(x-3)^2 -1 + 1 = -25 + 1 or
2(x-3)^2 + 0 = -24 or
2(x-3)^2 = -24 (*)
Case 1: x is a real number. In that case as the square (x-3)^2 is always >0, so (*) has no real solution.
Case 2. x is a complex number ( a + bi, where a <> 0). In this case divide both sides of (*) by 2,
(x-3)^2 = -24/2 = -12 =>
x-3 = +\- sqrt(-12) = +\- sqrt (12 * -1) = +\- sqrt (4 * 3 * -1) = +\- 2 sqrt(3) * i
where i = sqrt (-1).
Add 3 to both sides gives
x = 3 +\- 2 sqrt(3) i
Thank you,
