Answer:

Step-by-step explanation:
Let
x -----> Hermione was earning before the pay raise
we know that

so
The linear equation that represent this problem is

Solve for x
Divide by 1.05 both sides


(2/3)*(c-18)=7 <em>(Multiply terms on both sides of equation by 3)</em>
2(c-18)=21
2c-36=21
2c=57
c=57/2
c=28.5
Answer:
She would need 144 square feet of carpet.
Step-by-step explanation:
Since the pen is 12 feet by 12 feet you would multiply 12 by 12 for your answer of 144 square feet.
Parallel lines have same same slope with different c values. comparing the given equation to y=mx+c. m=3 and c=-2. for the parallel line the c is different.
now apply the values of (0,4) in the equation y=3x+c and solving for C gives
the REQUIRED LINE EQUATION as y=3x+4
