Graph the function y=<img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20-2-5" id="TexFormula1" title="\sqrt{x} -2-5" alt="\sqrt{
Rashid [163]

Answer:

(3, -4)

Step-by-step explanation:

The correct equation is:

y=\sqrt{x-2}-5

From the list of given points, we have to identify which point lies on the graph. This can be done by using the value of x-coordinates from the given points and see if they result in the corresponding y-coordinate:

For point (1, 4)

y=\sqrt{1-2}-5=\sqrt{-1}-5, This is not equal to 4, so it does not lie on the graph of given function.

For point (3, -4)

y=\sqrt{3-2}-5=\sqrt{1}-5=-4, The answer ans corresponding y-coordinate are the same. This means, (3, -4) point lies on the graph of given function.

Likewise, checking for 3rd and 4th point we find out that they do not lie on the graph.

So the correct answer is (3, -4)

The solution set of the inequality 2x − y &gt; 2 consists of all the points __ ? the line __ ?
GalinKa [24]

Answer:

  • b - below; y = 2x − 2

Step-by-step explanation:

  • 2x − y > 2
  • 2x - y + y - 2 > 2 + y - 2
  • 2x - 2 > y
  • y < 2x - 2

Solution is the points below the line y = 2x - 2

<u>Correct option is:</u>

  • b - below; y = 2x − 2

Ten large marbles weigh as much as 14 small marbles. How many large marbles weigh as much as 35 small marbles?
Paladinen [302]
To get the answer we can use proportion
10 large ------------- 14 small
x large -------------- 35 small
crossmultiply
10*35=x*14
350=14x            /:14
350:14=14x:14
25=x-its the answer
