Answer:
value of x = 2.8
Step-by-step explanation:
By law of cosines,
Step-by-step explanation:
1) x/20 = -9
By cross multiplication,
x = -180
2) -168 = -14k
k = -168/-14
k = 12
3) -5m = -50
m = 10
4) -320 = -20n
n = 16
5) -4 = x - 5
x = 1
6) -6(-8 + n) = -54
42 - 6n = -54
-6n = -54 -52
6n = 106
n = 17.6
7) 3(x - 9) = -3
3x - 27 = -3
3x = 24
x = 8
8) 9k + 3 = -78
9k = -81
k = -9
9)4 + (n/4) = 8
By taking LCM,
16 + n/4 = 8
16 + n = 32
n = 16
10) -5r + 7 = -73
-5r = -80
r = 16

Answer:
x = 
y
Step-by-step explanation:
Given x : y = 2 : 3
Express the ratios as a fraction, that is
= ( cross- multiply )
3x = 2y ( divide both sides by 3 )
x = y
Answer:
The answer is 206.8. But you want me to round to the nearest cent so the real answer is $207.00
Step-by-step explanation:
Answer:
D) x-int (-3,0), y-int (0,2)
Step-by-step explanation:
x-intercept is where the line crosses the x-axis
y-intercept is where the line crosses the y-axis
From inspection of the graph,
x-intercept = (-3, 0)
y-intercept = (0, 2)
