Answer:
3
Step-by-step explanation:
C(n) = 5n, 0 ≤ n ≤ 10 You would use this equation for finding the cost of 10 shirts. Since 10 is equal to 10.
C(n) = 5n, 0 ≤ n ≤ 10 ← You can ignore the 0 ≤n ≤10 part.
C(10) = 5(10) Input the value 10 as x.
C(10) = 50 Simplified
Next,
C(n) = 4n + 5, n > 10 You would use this equation for finding the cost of 12shirts. Since 12 is greater than 10.
C(n) = 4n + 5, n > 10 ← You can ignore the n>10 part.
C(12) = 4(12) + 5, n > 10 Input the value of 12 as x.
C(12) = 48 + 5 Simplify
C(12) = 53
Finally,
The question is asking you to find the difference between the cost of 12 shirts and the cost of 10 shirts. So the formula would be C(12) - C(10).
C(12) - C(10)
(53) - (50) Input the values of C(12) and C(10).
= 3 Simplify.
The answer is 3.

Answer:
y=-2x+13
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-3)/(4-5)
m=2/-1
m=-2
y-y1=m(x-x1)
y-3=-2(x-5)
y=-2x+10+3
y=-2x+13
Hello,
Let's w the width , l the length, p the perimeter.
w=l-5
p=2(l+w)=2(l+l-5)=4l-10
4l-10=122
==>4l=122+10
==>4l=132
==>l=132/4
==>l=33
So w=33-5=28
Proof:
2*(33+28)=2*61=122
B. 1,147, I’m not quite sure
