Answer:
-9>x
Step-by-step explanation:
5(x+4)>2x-7
5x+20>2x-7
5x+20>2x-7
<u> +7 +7</u>
5x+27>2x
↓
5x+27>2x
<u>-5x -5x</u>
27>-3x
↓
<u>27>-3x </u>
-3 -3
= -9>x
note that gradient =
at x = a
calculate
for each pair of functions and compare gradient
(a)
= 2x and
= - 1
at x = 4 : gradient = 8 and - 1 : 8 > - 1
(b)
= 2x + 3 and
= - 2
at x = 2 : gradient = 7 and - 2 and 7 > - 2
(c)
= 4x + 13 and
= 2
at x = - 7 : gradient = - 15 and 2 and 2 > - 15
(d)
= 6x - 5 and
= 2x - 2
at x = - 1 : gradient = - 11 and - 4 and - 4 > - 11
(e)
y = √x = 
= 1/(2√x) and
= 2
at x = 9 : gradient =
and 2 and 2 >
