Solve for x in the first equation, then solve the system using substitution. Write your answer as (x, y).
OleMash [197]
2x - 6y = 14
2x = 6y + 14
x = 3y + 7.....so sub in 3y + 7 for x in the other equation

4x - y = 9
4(3y + 7) - y = 9
12y + 28 - y = 9
12y - y = 9 - 28
11y = - 19
y = -19/11

x = 3y + 7
x = 3(-19/11) + 7
x = -57/11 + 7
x = -57/11 + 77/11
x = 20/11

solution is : (20/11, -19/11) <==

Derrick's Doggie Day Care charges a $12 registration fee plus $5 per hour for pet sitting. Pauline's Pooch Park charges $3 per h
sweet-ann [11.9K]

Answer:

12 + 5h \leq 18 + 3h

Step-by-step explanation:

Given

Represent Derrick's with D and Pauline's with P

For D

Registration Fee = $12

Hourly Charges = $5

For P

Registration Fee = $18

Hourly Charges = $3

Required

Represent as an inequality such that D is at most of P

First, we need to represent both as an expression:

For D

D: 12 + 5h

For P:

P:18 + 3h

Since D is at most of P;

This implies that:

D \leq P

So, we have:

12 + 5h \leq 18 + 3h
