i need help with x and y input output tables for 7th grade i don't understand what 5x means or what to do!
Math hw problems:
1. y=4x+3 x=1,2,5,10,20
2.d=3.5t t=1,2,5,10,20
Please help ASAP!!!!!
whatis y=4x+3
to figure out what x is you have to get the numbers to cancel out so that the vairiable will stand alone
Of course, I can help you with input-output tables for the given equations. Let's start by understanding what "5x" and "4x" mean.
In mathematics, the letter "x" is often used to represent an unknown value or variable. When you see "5x" or "4x," it means multiplying the number "5" or "4" by the unknown value or variable "x."
Now, let's work on the first problem:
1. y = 4x + 3, where x = 1, 2, 5, 10, 20
To create an input-output table, we substitute each given value of "x" into the equation and solve for "y."
When x = 1:
y = 4(1) + 3
y = 4 + 3
y = 7
When x = 2:
y = 4(2) + 3
y = 8 + 3
y = 11
When x = 5:
y = 4(5) + 3
y = 20 + 3
y = 23
When x = 10:
y = 4(10) + 3
y = 40 + 3
y = 43
When x = 20:
y = 4(20) + 3
y = 80 + 3
y = 83
Now, let's move on to the second problem:
2. d = 3.5t, where t = 1, 2, 5, 10, 20
Using the same approach, we substitute each given value of "t" into the equation and solve for "d."
When t = 1:
d = 3.5(1)
d = 3.5
When t = 2:
d = 3.5(2)
d = 7
When t = 5:
d = 3.5(5)
d = 17.5
When t = 10:
d = 3.5(10)
d = 35
When t = 20:
d = 3.5(20)
d = 70
Now you have the values for "y" and "d" corresponding to each given value of "x" and "t" in the input-output tables.
