Answer:
y = 3x + 9
Step-by-step explanation:
y = 3x + 6
Parallel slope = 3
(-2, 3)
Slope-intercept:
y - y1 = m(x - x1)
y - 3 = 3(x + 2)
y - 3 = 3x + 6
y = 3x + 9
10% is $8.00 so 20% is $16 and 80-16= 64 so the sale cost is $64.00
Answer:
x+7
Step-by-step explanation:
25x - 6x - 18x + 7
x + 7
To answer, subtract x² from both sides of the equation to give us,
y² = -x² + 9
Then, we derive the equation in terms t.
2y(dy/dt) = -2x(dx/dt)
Substituting the known values from the given,
2(sqrt6)(dy/dt) = -2(-sqrt3)(20)
The value of dy/dt is 14.14.
