Answer: supply curve and the demand curve
Step-by-step explanation: When two lines on a diagram cross, this intersection usually means something. On a graph, the point where the supply curve (S) and the demand curve (D)
Answer:
124
Step-by-step explanation:
First subtract 6 to both sides.
![\sqrt[5]{249-2x} = 1](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B249-2x%7D%20%3D%201)
Then take the 5th power of both sides to remove the radical.
Which is essentially:
-2x = 1 - 249
-2x = -248
Divide both sides by -2
x = 124
And there ya go :)
3(12 - 2n) = 36
36 - 6n = 36
-6n = 0
n = 0 <== ur number
Answer:
5.7
Step-by-step explanation:
The altitude divides right triangle ABC into similar right triangles ADB and BDC. The ratios of short leg to long leg will be proportional in these similar triangles, so you have ...
AD/BD = BD/CD
Cross multiplying gives ...
AD·CD = BD²
(x+3)(2x+3) = 5²
2x² +9x = 16 . . . . . perform the multiplication, subtract 9
2(x² +4.5x) = 16
2(x² +4.5x +2.25²) = 16 +2(2.25²) . . . . . add 2(2.25²) to complete the square
2(x +2.25)² = 26.125 . . . . . write as a square
x +2.25 = √13.0625 . . . . . .divide by 2, take the positive square root
x = -2.25 +√13.0625 . . . . subtract 2.25 to find x
We want the value of CD, so ...
CD = 2x +3 = 2(-2.25 +√13.0625) +3
CD = -1.5 +2√13.0625 ≈ 5.7284
The length of CD is about 5.7 units.
