Answer:
r=0.5
Step-by-step explanation:
0.125r+0.25r-0.0625=0.25+r
0.375r-0.0625=0.25+r
0.375r-r=0.25+0.0625
-0.625r=0.3125
r=0.3125/0.625
r=0.5
Using the slope intercept formula, we conclude that the slope of line p:y=3x-3 is 3.Since line k is perpendicular to line p it must have a slope that is the negative reciprocal.Therefore the slope of line k is -1/3.Using the formula y-9=-1/3(x-(-7)) and doing the math we will end up with k:y=-1/3x+34/3

Step-by-step explanation:
<u>Step 1: Define</u>
d(x) = 5x - 12
d(-4) is x = -4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: d(-4) = 5(-4) - 12
- Multiply: d(-4) = -20 - 12
- Subtract: d(-4) = -32
The answer will be:- <u>x = 1</u>
By the way your question was asked, the unit rate would be one foot per inch, or a 1ft:1in ratio.
