Y = 4.99x
x = # of items
y = total cost

here/

Step-by-step explanation:

charges a cost per pound plus a fixed fee to ship a package. the total cost, f(x) ... f(x)=4.99x+5.75. which part of the function represents the fixed fee? 2 ... the cost of items purchased and y represents the total cost of shipping.

the fixed fee is the part of $5.75

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
