Question

Can you answer these for me please and re-think your answer

Answer 1

Answer:

Its D,,, because there is a whole on -3 we don't take it as part of the equation

Answer 2

Answer:

For Q4 It's (A)

For Q5 it's (D)

Q4-

3(1+x) < x+6 --------- substitute 3

3+3x < x+6

-x. -x. ----- get rid of the same variable because we need to find only one x

_____________

3+2x < 6

-3. -3. ------ to find x we move the 3 to the 6

________

2x < 3

to find x ----> I get rid of the 2 by dividing it by itself

so---- 2x/2 < 3/2

{{{{{x < 1.5 }}}}

this sign "<" means smaller so x is smaller than 1.5

the possible values for x are ---- x={ 0, 1, 0.5.....}

So it's A

_____________________

for Q5.

the uncolored circle O means that the sign is either < or > but if it was colored • then it's ≤ or ≥.

Here, the uncolored circle is on the -3 with a line connected to it towards the largest numbers in the number line.

this shows that x is larger than -3

So, X > -3 ------- (D)
