Question

Determine if each statement is true or false when x = 2.

a) 4x2 – 8x + 1 > 3x – x2/4

b) 3x – x/2 ≤ 5

@marigirl
last problems :)

Answer 1

just substitute x=2 into the equations

Answer 2

so
a) 4x^2 – 8x + 1 > 3x – x2/4
when ever you see a x you write it with a 2
\[4(2)^2-8(2)+1> 3(2)-\frac{ 2^2 }{ 4 }\]

So tell me what number we will have on your left side and what number will it result to on our right side
