Answer:
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
Step-by-step explanation:
We are told she would like to have at least 40 cupcakes and cookies combined.
If a is number of cupcakes and b is number of cookies, then this inequality is;
a + b ≥ 40
Secondly, we are told she would like to have at most 5 more cupcakes than cookies.
Thus, the inequality is;
a + 5 ≤ b
Lastly, we are told that cupcakes sell for $2.50 and cookies for $1.50
Thus, the inequality is;
2.50a + 1.50b ≤ 105
Finally, the 3 inequalities are;
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
Well first just multiply the things in the parenthesis by 3 and get -15c + 12d and then subtract 15 from 11 (because of the c) and get -4c +12d
P = 3
Step-by-step explanation:
Multiply both sides by 3
48-9p=2p+15
Add 9p to both sides
48=2p+15+9p48=2p+15+9p
Simplify 2p+15+9p2p+15+9p to 11p+15
48=11p+15
Subtract 15 from both sides
48−15=11p
Simplify 48-15 to 33
33=11p
Divide both sides by 11
\frac{33}11=p11/33=p
Simplify 11/33 to 3
3=p
Switch sides
p=3

Answer:
y = -4/3x - 1/3
Step-by-step explanation:
-3/2x+2y=-7
2y = 3/2x - 7
y = 3/4x - 7/2
y = -4/3x + b
5 = -4/3(-4) + b
5 = 16/3 + b
-1/3 = b
is the boundary of the triangle 
, then by Green's theorem
