Answer:

Step-by-step explanation:

To find the perpendicular equation of a line,
You need the product of their gradients to be -1

Divide both sides by 
? = 2
The gradient of the perpendicular line is 2
Straight line formula is in the form 

We're nearly there, we just need to find out c.
Luckily, we're given a point 



We then end up with...

Answer:
$565.73 and the interest is $90.73
Step-by-step explanation:
A=475(1+0.061)^1⋅3
A=475⋅1.063
A=475⋅1.191016
A=565.73
To find interest:
A=P+I
565.73II=475+I
I=565.73−475
I=90.73
Answer:
x = 21
Step-by-step explanation:
Step 1: Write out equation
-5x - 72 = -12x + 75
Step 2: Add 5x to both sides
-72 = -7x + 75
Step 3: Subtract 75 on both sides
-147 = -7x
Step 4: Divide both sides by -7
21 = x
Step 5: Rewrite
x = 21
That would be 35.5 quarts
