Answer
Step-by-step explanation:
(15x-8y)=52
180=90+52+x
x=38
System of equations:
15x-8y=52
6x+14y=38
y=-6.5+15/8x
6x+14(-6.5+15/8x)=38
6x-91+26.25x=38
32.25x=129
x=4
15(4)-8y=52
60-8y=52
-8y=-8
y=1
x=4
Answer:
3150
Step-by-step explanation:
2325/155,000 = 0.015 = 1.5%
210,000 x 1.5% = 210,000 x 0.015 = 3150
7x - 5y = 21....(4,?)...so sub in 4 for x and solve for y
7(4) - 5y = 21
28 - 5y = 21
-5y = 21 - 28
-5y = - 7
y = 7/5
check..
7(4) - 5(7/5) = 21
28 - 35/5 = 21
28 - 7 = 21
21 = 21 (correct)
the other coordinate is 7/5......(4,7/5)
