Answer:
x = 8
Step-by-step explanation:
Corresponding segments are proportional.
(3x +1)/10 = (7x -1)/22
11(3x +1) = 5(7x -1) . . . . . . multiply by 110
33x + 11 = 35x -5 . . . . . . eliminate parentheses
16 = 2x . . . . . . . . . . . add 5-33x to both sides
8 = x . . . . . . . . . . divide by 2
Combine like terms. remember to keep the signs.
5x² - 2x² = 3x²
3x - (-6x) = 3x + 6x = 9x
4 - (-3) = 7
3x² + 9x + 7 = Ax² + Bx + C
9 = B, because 9 is in the B's place
9 is your answer
hope this helps

The given equation is:
![y= \sqrt{x+3}](https://tex.z-dn.net/?f=y%3D%20%5Csqrt%7Bx%2B3%7D%20)
We need to find which set of parametric equations, result in the equation given above. The correct answer is option A.
![x=5t, y= \sqrt{5t+3}](https://tex.z-dn.net/?f=x%3D5t%2C%20y%3D%20%5Csqrt%7B5t%2B3%7D%20)
From first equation, we can write t =x/5. Using this value in second equation, we get:
![y= \sqrt{5( \frac{x}{5} )+3} \\ \\ y= \sqrt{x+3}](https://tex.z-dn.net/?f=y%3D%20%5Csqrt%7B5%28%20%5Cfrac%7Bx%7D%7B5%7D%20%29%2B3%7D%20%20%5C%5C%20%20%5C%5C%20%0Ay%3D%20%5Csqrt%7Bx%2B3%7D%20)
Thus the set of equations in option A result in the given relation.
So, the answer to this question is option A
Answer:
272/-13 or −20.923
Step-by-step explanation:
To solve this equation you need to isolate the variable.
First, add 71 to both sides
-13x-71+71=201+71
-13x=272
Then, divide both sides by -13
-13x/-13=272/-13
So, x=272/-13 or −20.923
