What is the value of X in this proportion? (image of the proportion included)
Answers
4x/50 = 2/x take 4x and multiply it by the denominator in the other fraction it = 4x^2 do the same for the 2 &50 you get 100 now you have 4x^2=100 take the 4 divide it on both sides so 4/4=0 and 4/100=25 now you have
x^2=25 find the square root of 25= (5) so X=5

Answer:
(- 5, 1 )
Step-by-step explanation:
- 6x - 14y = 16 → (1)
- 2x + 7y = 17 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the x- term
6x - 21y = - 51 → (3)
Add (1) and (3) term by term to eliminate x
0 - 35y = - 35
- 35y = - 35 ( divide both sides by - 35 )
y = 1
Substitute y = 1 into either of the 2 equations and solve for x
Substituting into (1)
- 6x - 14(1) = 16
- 6x - 14 = 16 ( add 14 to both sides )
- 6x = 30 ( divide both sides by - 6 )
x = - 5
solution is (- 5, 1 )

Answers
x⁴ - 8x² + 16 = 0 + 16
x⁴ - 4x² - 4x² + 16 = 16
x²(x²) - x²(4) - 4(x²) + 4(4) = 16
x²(x² - 4) - 4(x² - 4) = 16
(x² - 4)(x² - 4) = 16
(x² - 4)² = 16
The answer is B.

If:
then the line x = a is a vertical asymptote.
For x = 0:
f ( 0 ) = 3 * cot 0 - 4 = ∞
For x = +/- 2 π :
f ( 2 π ) = 3 * cot π - 4 = - ∞
Answer:
A ) x = 0 and C ) x = +/- 2π
Answer:
x=0 or ±2 nπ where n belongs to natural numbers.
Step-by-step explanation:
The " vertical asymptote " is a vertical line that the graph of a function approaches but never touches. To find the vertical asymptotes of a rational function we set denominator=0.
We are given function y=3 cot((1/2)x)-4
which could also be written as
for denominator to be equal to 0 we must have sin((1/2)x)=0
⇒ (1/2)x=0
⇒ x=0 or ±2 nπ where n belongs to natural numbers.
Hence, the vertical asymptotes of the given function is x=0 or ±2 nπ where n belongs to natural numbers.

Isolate the Y getting:
2x-17=y and x-10=y
Then bring the two equations together. Sub in the one equation for y.
2x-17 = x-10
The answer for x would be 7 (X=7)
Then pick an equation and sub in 7 for x to get your Y.
x-y=10
7-y=10
Subtract 7
-y=3
Divide the -1 from the y (Hopefully you learned why there's a 1 there)
y=-3
Answer is X=7 and Y=-3 or (7, -3)
