Answer:
-3
Step-by-step explanation:
Answer: It’s the third option
Step-by-step explanation:
<em>For</em><em> </em><em>the</em><em> </em><em>attached</em><em> </em><em>image</em><em>,</em><em> </em><em>note</em><em> </em><em>that</em><em> </em><em>slope</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>thing</em><em> </em><em>as</em><em> </em><em>gradient</em><em>.</em>
1) y = 2x + 4
2) Substituting in x = 1 and y = 1,
1 = 4(1) + c
1 = 4 + c
c = -3
So, the equation is y = 4x - 3
The cost would be at least $755.1302 to build the deck.
The deck is in the shape of a rectangle. Therefore,
<h3>Area of rectangle</h3>
where
l = length
w = width
length = 9.4 ft
width = 6.7 ft
area = 9.4 × 6.7 = 62.98 ft²
Therefore,
1 ft² of lumber = $11.99
62.98 ft² of lumber = ?
cross multiply
cost = 62.98 × 11.99 = $755.1302
