For f(x) = 2x + 1 and g(x) = x2 - 7, find (f+ g)(x). O A. x2 + 2x + 8
O B. 2x2 - 15
O c. x2 + 2x - 6
O D. 2x3 - 6
Right answer please

C.) x2 + 2x - 6

Step-by-step explanation:

f(x) = 2x + 1

g(x) = x2 - 7

(2x + 1) + (x2 - 7)

combine like terms

x2 + 2x - 6

1st part is 64,000,000

2nd part 500,000

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
