Given f(x) = x ^ 2 - 6x + 8 and g(x) = x + 2 solve f(x) = g(x) . Use the tables below to help you, but please explain how you ca
Travka [436]

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = x² - 6x + 8 and g(x) = x + 2

To solve f(x) = g(x), equate the right sides, that is

x² - 6x + 8 = x + 2 ← subtract x + 2 from both sides

x² - 7x + 6 = 0 ← in standard form

(x - 1)(x - 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 6 = 0 ⇒ x = 6

These solutions can be verified from the tables, that is

f(x) = g(x) = 3 ← when x = 1

f(x) = g(x) = 8 ← when x = 6

What is the equation of this circle in standard form?
creativ13 [48]

Answer:

Option C.

Step-by-step explanation:

Note : In the given points one point is (8,-2) instead of (-6,-2).

The standard form of a circle is

(x-h)^2+(y-k)^2=r^2

where, (h,k) is center of circle and r is radius.

It is given that center of the circle is (-1,-2). So,

h=-1,k=-2

(x-(-1))^2+(y-(-2))^2=r^2

(x+1)^2+(y+2)^2=r^2    ...(1)

It is given that the circle passing through the point (8,-2),(-1,5),(6,-2),(-1,-9).

Substitute x=6 and y=-2 in equation (1).

(6+1)^2+(-2+2)^2=r^2

(7)^2+(0)^2=r^2

49=r^2

Substitute r^2=49 in equation (1).

(x+1)^2+(y+2)^2=49

Therefore, the correct option is C.

Write a rule for the linear function. (2,5) and (1,1)
Oksi-84 [34.3K]

The graph of a linear function is a straight line. f(0) = -5 means that (0,-5) is a point on the line. Similarly, (-5,-6) is also a point on the line. [ Slope of line = m = [-6-(-5)]/[-5-0] = -1/(-5) = 1/5 Using the point-slope form, an equation of the line is: y - (-5) = (1/5)(x - 0) So, y = (1/5)x - 5 ]
