Answer:
(4,5)
Step-by-step explanation:
5x+y=25 equation 1
-3x+2y=-2 equation 2
y=25-5x isolate y from equation 1
-3x+2(25-5x)=-2 substitute y value into equation 2
-3x+50-10x=-2
-13x=-52
x=4
solve for y by inserting x value into either equation.
5x+y=25
5(4)+y=25
20+y=25
y=5
Answer:
x² + 4x - 12, remainder - 60
Step-by-step explanation:
Using synthetic division to divide
Since dividing by x - 1, evaluate for x = 1
1 | 1 3 - 16 - 48
↓ 1 4 - 12
---------------------------
1 4 - 12 - 60 ← degree 2 polynomial
quotient = x² + 4x - 12, remainder = - 60
Hence
= x² + 4x - 12 -
Answer:
The 1st one
Step-by-step explanation:
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
