X⁶ + 1000
x⁶ - 10x⁴ + 10x⁴ + 100x² - 100x² + 1000
x⁶ - 10x⁴ + 100x² + 10x⁴ - 100x² + 1000
x²(x⁴) - x²(10x²) + x²(100) + 10(x⁴) - 10(10x²) + 10(10)
x²(x⁴ - 10x² + 100) + 10(x⁴ - 10x² + 100)
(x² + 10)(x⁴ - 10x² + 100)
Diagonals of a rect. are equal...
diagonals bisect each each other...
from these two properties we get ,
4x-12 = 1/2 (7x-18)
2 (4x-12)=7x-18
8x-24=7x-18
x=6

Answer:
The speed of the jet is 347 mph and the speed of the wind is 18 mph.
Step-by-step explanation:
We have the following:
x = the speed of the jet in still air.
y = the speed of the wind
we know that the speed is equal to:
v = d / t
therefore the distance would be:
d = v * t
if we replace with the information of the exercise we have:
3 * (x + y) = 1095
3 * (x - y) = 987
we must solve this system of equations, add both equations and we are left:
3 * x + 3 * y = 1095
3 * x - 3 * y = 987
3 * x + 3 * y + 3 * x - 3 * y = 1095 + 987
6 * x = 2082
x = 2082/6 = 347
now to calculate y, we replace:
3 * (347 + y) = 1095
1041 + 3 * y = 1095
3 * y = 1095 - 1041
y = 54/3 = 18
The speed of the jet is 347 mph and the speed of the wind is 18 mph.
Answer:
find y=mx+b
y=-2/3x+4
so m= -2/3
b= 4
what you want to do is start at 4 since b and go down 2 times then right 3 times or go up 2 times and left 3 times or just plug in the equation in desmos graphing calculator
Answer:
35 months
Step-by-step explanation:
Given that,
You deposit a total of $780 in 1 year i.e. in 12 months
We need to find how many months does it take for you to deposit $2275.
$780 in 12 months
1$ in
$2275 in,
Hence, it will take 35 months to deposit $2275.
