Answer:
C. Natasha has been charged by $1.85 for her purchase.
Step-by-step explanation:
A11 1 * [ (2*5) - (5*2)] = 0
a12 = -4 *(5*5) - 2*1) = 23*-4 = -92
a13 = 4 * (5*5) - (1*2) = 23 * 4 = 92
a21 = 0
a22 = 2 * (5-4) = 2
a23 = -2 * (5-4) - -2
a31 = 0
a32 = -5*(2-20) = 90
a33 = 5 * (2-10) = -90
Adding these gives zero
Answer is B:- 0
Answer:
$563.9
Step-by-step explanation:
7.45n + 8.8p = profit
7.45(26) + 8.8(39) = profit
193.7 + 343.2 = profit
563.9 = profit
First of all we have to find the slope
m = y₂-y₁ / x₂-x₁
m = -8 + 16 / -10 + 8
m = 8/-2
m = -4
y-y₁ = m (x-x₁)
y + 8 = -4 (x + 10)
y + 8 = -4x - 40
y = -4x -40 - 8
y = -4x -48
Answer:
The process of finding the derivative of dependent variable in an implicit function by differentiating each term separately by expressing the derivative of the dependent variable as a symbol and by solving the resulting expression for the symbol.
