Answer:
100 silver coins and 175 bronze
Step-by-step explanation:
let x be the number of silver coins and y the number of bronze coins.
Worth of these coins together = 6x/(5)+0.08/(10)y
=1.2x+0.008y
Weight of one silver coin = 125/5 = 25 gm
and one bronze coin = 500/10 = 50 gms.
Weight of these coins together = 25x + 50y
Equate these two items i.e. value and weight to actuals given.
i.e. 1.2x+0.08y = 134 and ... i
25x+50y = 11 kg 250 gm = 11250 gms. ... ii
Divide the second equation by 25
x+2y = 450 ... iii
Multiply I equation by 25
30x+2y =3350 ... iv
iii-iv gives -29x = -2900 or
x =100
Substitute in x+2y = 450
2y = 350 or y =175
G, which is 2 the line directly hits the center of (0,2)
Answer:
The answer to your question is y = -2x - 2
Step-by-step explanation:
Data
Point = (-4, 6)
slope = m = -2
Process
1.- Substitute the values in the formula point-slope
y - y1 = m(x - x1)
y - 6 = -2(x + 4)
2.- Simplify
y - 6 = -2x - 8
y = -2x - 8 + 6
3.- Result
y = -2x - 2 slope = -2
y-coordinate = -2
