Someone please help me on this math problem!
Galina-37 [17]

Look at the picture.

Therefore we have the equation:

10y - 29 = 7y + 19       <em>add 29 to both sides</em>

10y = 7y + 48          <em>subtract 7y from both sides</em>

3y = 48      <em>divide both sides by 3</em>

y = 16



3x + 7 = 5x - 21            <em>subtract 7 from both sides</em>

3x = 5x = -28         <em>subtract 5x from both sides</em>

-2x = -28     <em>divide both sides by (-2)</em>

x = 14

Which of the following options have the same value as 20% of 45 (choose 3 answer)
11Alexandr11 [23.1K]

Answer:

20% of 45 is 9,  

Step-by-step explanation:

So the answer must be 9 for an example 50% of 18 is 9  because to find 50% of something simply divide by 2 .10% of 90 is 9 because to find 10% of something divide by 10. 25% of 36 is 9 because you divide by 4 to get 25% of anything.

Is the relation a function? If so why or why not? {(-3,2),(-1,0),(1,0),(5,-2)}
Anastasy [175]

Answer:

It's a function

Step-by-step explanation:

Functions can only have one output for each input. And since all the x values for each point are different, there is only one output (y-value) for each input(x-value).
