Answer: 55
Step-by-step explanation:
D=m/v
D=14.4
M=792
V= unknown
14.4=792/v- multiply both sides by V
V • 14.4=792-divide both sides by 14.4
V=55
Answer: y = 17x
Step-by-step explanation:
Note that the equation that will be used is: y = mx + b,in which m = slope and b = y-intercept.
Solve for b:
0 = 17(0) + b
Simplify:
0 = 0 + b
b = 0
Equation: y = 17(x)
~
Y = 2
X = 1
M = -2
B = ?
y=mx+b
2=-2(1)+b
2= -2 + b
+2 +2
4 = b
Therefore the equation is
y = -2x + 4
$ 40 ..... 100 %
$ 28 ..... x %

The % of change is 70 %.
This is equivalent with:
- the final price ($ 28) is 70 % from the initial price ($ 40)
- the initial price ($ 40) was reduced with 30% giving the new price as:
