For f(x) =2x+1 and g(x)=x^2- 7, find (f- g(x). OA. -x^2+-6
OB. 2x^2-15
OC. -x^2x+ 8
OD. x^2- 2x-8

the answer is c)8

step-by-step explanaction:

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
