Evaluate the function f(x)=x^2-5x+ 5 at the given values of the independent variable and simplify

11111nata11111 [884]

Step-by-step explanation:

The given function is :

$f(x)=x^2-5x+ 5$

(a) To find f(9), put x = 9 in the above expression.

$f(9)=9^2-5(9)+ 5=41$

(b) To find f(x+7), put x = x+7 in the above expression.

$f(x+7)=(x+7)^2-5(x+7)+ 5\\\\=x^2+14x+49-5x-35+5\\\\=x^2+9x+19$

$f(-x)=(-x)^2-5(-x)+ 5\\\\=x^2+5x+5$

Hence, this is the required solution.

Two trains are 500 miles apart when they first enter a collision course. If, after two hours, the distance between them is 300 m

MrRissso [65]

Answer:

The faster train goes 60mph

Step-by-step explanation:

s= speed

s+20 is the faster train.

Then you are given:

200/s+s+20=2

200=2*(2s+20)

4s+40=200

4s=160

s=40 is the slower train

40+20= speed of faster one

s=60 ;)
