Answer:
x=5, y=1. (5, 1).
Step-by-step explanation:
6x+4y=34
3x-y=14
---------------
y=3x-14
6x+4(3x-14)=34
6x+12x-56=34
18x=34+56
18x=90
x=90/18
x=5
3(5)-y=14
15-y=14
y=15-14
y=1
Answer:
6.9
Step-by-step explanation:
12 x 4 = x^2
48 = x^2
x = 6.9
Answer:
c, d. see attached
e. about 2.96 miles; about $1.63 million
Step-by-step explanation:
e. The x-coordinates of points A and B are 1/3 and 2/3 of the x-coordinate of "Downtown", respectively. The y-coordinates of A and B are 2/3 and 1/3 of the y-coordinate of "Town pool", respectively. Then the distances from A and B to the Mall can be found using the Pythagorean theorem:
A to Mall = √(4² +(10/3)²) = √(244/9) ≈ 5.20683 . . . miles
B to Mall = √(8² +(5/3)²) = √(601/9) ≈ 8.17177 . . . miles
The difference in distance is ...
(BM -AM) = 8.17177 -5.20683 = 2.96493 . . . miles
The mall is about 2.96 miles farther from point B than from point A.
The additional cost is the difference in miles multiplied by the cost per mile:
(2.96 mi)($0.550 M/mi) = $1.63 M
The additional cost of the longer road is about $1.63 million.
