Five times a number decreased by nine is equal to twice the number increased by 23. Which equation could be used to solve the problem?
5x - 9 = x + 23
5x - 9 = 2x + 23
5x + 23 + 2x = 23
5x + 23 = 2x + 23

Step-by-step explanation:

"Five times a number" is '5x'.

"Decreased by nine is" '-9'.

"Is equal to" is '='.

"Twice the number" is '2x'.

"Increased by 23" is '+ 23'.

Put them together: 5x-9=2x+23

5x - 9 = 2x + 23 should be the correct answer.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
