Weird question.
logically, the only answer that can make sense is a negative one since it is a decreasing slope.
the secant is the average rate of change (and is 1/tangent)
the tangent is the instantaneous rate of change. (1/secant)
we want the first one which is:<span><span><span><span>Δx</span><span>Δy</span></span>=<span><span>Δ weeks</span><span>Δ lbs</span></span>=<span><span>5−0</span><span>137−150</span></span>=<span>5<span>−13</span></span>=−0.3846</span></span>
1st = 100% - 20% = 80%
2nd= 100%-15% = 85%
Net Price Factor = 0.8 x 0.85 = 0.68
Net Price = $1899 x 0.68
Final Net Price = $1,291.32
Total Discount= $1899 - 1,291.32 = $607.68
Answer:
4y = 36-x
Step-by-step explanation:
A linear function is in the form
y = mx + b
for g(0) = 7 ;
x = 0 and y = 9
So ;
9= 0(x) + b
b = 9
For g(8) = 7
x = 8 and y = 7
7 = 8m + 9
7-9 = 8m
8m = -2
m = -2/8 = -1/4
So the equation is;
y = -1/4x + 9
Multiply through by 4
4y = -x + 36
Answer:
7 sec in the air, 5 in the water.
Step-by-step explanation:
make it into a linear equation
16x + 3y = 127
x+y=12
(7,5)
