Show that 4x - x? – 7 is always negative. Help

Verizon [17]

Question No 7

Answer:

Please check the explanation.

Step-by-step explanation:

Show that 4x - x² - 7 is always negative.

Given

4x - x² - 7

4x - x² - 7 is always negative because:

-x²-7 will alwas be negative for all the values of x,

The value of - x² - 7 will always be less than 4x for all the values of x

Hence, 4x - x² - 7 is always negative

For example,

let suppose we enter x = 1

$4(1)-1^{2} -7\\=4-1-7\\=4-8\\=-4$

let suppose we enter x = -1

$4(-1)-(-1)^{2} - 7\\= -4 - 1 - 7\\= -12$

Answer:x=7

Step-by-step explanation:

Here AD=6

AB=6 (tangents drawn from external point to a circle are equal)

Then BC=13-6=7

Now, CE=BC=7(tangents drawn from external point to a circle are equal)

EF=14-7=7

EF=FG=x=7(tangents drawn from external point to a circle are equal)
