Answer:
When x = 2, both expressions have a value of 18
The expressions have equivalent values for any value of x.
The expressions have equivalent values if x = 8.
Step-by-step explanation:
7x+4 3x+5+4x-1
Let x=2
7*2 +4 = 18
3*2+5+4*2-1 = 6+5+8-1=18
When x = 2, both expressions have a value of 18
The expressions are only equivalent for x = 4 and x = 6.
False, they are both equal when x=2
Try x=1
7+4 =11 3+5+4-1 = 11
They are equal with an odd value
When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
4 5-1 =4 false
The expressions are only equivalent when evaluated with even values. false
The expressions should have been evaluated with one odd value and one even value. my best guess is false, if it is true for 2 values it is true for all values
The expressions have equivalent values if x = 8. true
7*8 +4 = 60 3(8)+5 +4(8) -1 =60
The expressions have equivalent values for any value of x.
7x+4 3x+4x +5-1 = 7x+4
They are always equal
