<span>slope of -1/2 and a y-intercept of 4, so m = -1/2 and b = 4
using y = mx + b
y = -1/2x + 4
answer is </span><span>B. y= -1/2x +4</span>
Answer:
Total cost = 16
Step-by-step explanation:
In the equation of cost, we can see that each rose costs 3 and each petunia costs 2.5.
To find the total cost of two roses and four petunias, we can use the values r = 2 and p = 4 in the equation given, so:
Total cost = 3r + 2.5p = 3*2 + 2.5*4 = 6 + 10 = 16
So the total cost of two roses and four petunias is 16.
Using the modified Pythagorean equation sqrt((6-4)^2 + (2-(-2))^2 = c^2, you get the sqrt(4 + 16) or sqrt 20. Factor the 20 into sqrt(4x5) you get 2xsqrt(5)
