rule y=4x-5
input 3,5,7
help me find out the output values
y=4x-5
x=3
y=4*3-5=12-5=7
x=5
y=4*5-5=20-5=15
x=7
y=4*7-5=28-5=23
Input values 3,5,7
Output values 7,15,23
To find the output values for each input value of 3, 5, and 7, we will substitute each input value into the given rule y = 4x - 5.
For input value 3:
To calculate the output value, substitute x = 3 into the equation:
y = 4(3) - 5
y = 12 - 5
y = 7
So, when x = 3, the output value (y) is 7.
For input value 5:
To calculate the output value, substitute x = 5 into the equation:
y = 4(5) - 5
y = 20 - 5
y = 15
So, when x = 5, the output value (y) is 15.
For input value 7:
To calculate the output value, substitute x = 7 into the equation:
y = 4(7) - 5
y = 28 - 5
y = 23
So, when x = 7, the output value (y) is 23.
Therefore, the output values (y) for the given input values of 3, 5, and 7 are 7, 15, and 23 respectively.
