e value (in dollars) and x represent the number of years since purchase. Each of the cards’ resale values after 0, 1, 2, 3, and 4 years could be modeled by linear functions as follows:
Card A: y=3−0.8x ,Card B: y=7+2.7x ,Card C: y=15+0.9x ,Card D: y=14−3.1x ,Card E: y=5+0.25x

Select ALL cards that are decreasing in value.

Question 3 options:

a)

Card E: y=5+0.25x

b)

Card D: y=14−3.1x

c)

Card B: y=7+2.7x

d)

Card C: y=15+0.9x

e)

Card A: y=3−0.8x

What is the radius of the circle: (x+1)^2+(y-12)^2=25
lidiya [134]

Answer:

radius = 5

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here r² = 25 ( take the square root of both sides )

r = \sqrt{25} = 5
