Answer:
- y = -2/5x + 4, the last option
Step-by-step explanation:
<u>The formula:</u>
<u>The steps:</u>
- 1. -2 = (-2/5)(15) + b
- 2. -2 = -6 + b
- 3. b = 6 - 2
- 4. b = 4
<u>The result</u>
===========================================================
<u>What is the equation of the line in slope-intercept form? </u>
- Negative 2 = negative two-fifths x + 4
- y = negative two-fifths (15) + 4
- y = negative two-fifths x minus 4
- <u>y = negative two-fifths x + 4</u>
<h3>
Answer: 65 square units</h3>
===============================================
Work Shown:
P = area of triangle
P = 0.5*base*height
P = 0.5*5*4
P = 10 square units
----------------
Q = area of square
Q = side*side
Q = 5*5
Q = 25 square units
----------------
R = area of trapezoid
R = height*(base1+base2)/2
R = 5*(7+5)/2
R = 5*12/2
R = 60/2
R = 30
----------------
T = total area of the entire figure
T = P+Q+R
T = 10+25+30
T = 65 square units
Answer:
$805.0432
Step-by-step explanation:
118% was paid, so the original would be 82% of 981.76 (100-18), which is $805.0432 (rounds to $805.04)
