Answer:

-4x+y = -1

Step-by-step explanation:

-12x + 3y = -3

I am going to factorise 3 out from the left hand side of the equation.

3(-4x+y) = -3

Shift the 3 over to the right hand side and turn (×3) into (÷3).

-4x + y = $\frac{-3}{3}$

Evaluate.

-4x + y = -1

18 - 6(5 + 2) ÷ 3

18 - 6(7) ÷ 3

18 - 42 ÷ 3

18 - 14

An element with mass 780 grams decays by 17.1% per minute. How much of the element is remaining after 19 minutes to the nearest

Anit [1.1K]

Step 1
Formulate a recursive sequence modeling the number of grams after n minutes.
we have that
100%-17.1%-------------- > 82.9%------------> 0.829

a(n) = 780*[0.829^n]

for n=19 minutes
a(19)=780*[0.829^(19)]=22.1121 g---------------> 22.1 g

the answer is 22.1 g

Derivative Notation
The derivative of a constant is equal to 0
Derivative Property: $\frac{d}{dx} [cf(x)] = c \cdot f'(x)$
Trig Derivative: $\frac{d}{dx} [cos(x)] = -sin(x)$

Step-by-step explanation:

Step 1: Define

g(x) = 8 - 10cos(x)

x = 0

Step 2: Differentiate

Differentiate [Trig]: g'(x) = 0 - 10[-sin(x)]
Simplify Derivative: g'(x) = 10sin(x)

Step 3: Evaluate

Substitute in x: g'(0) = 10sin(0)
Evaluate Trig: g'(0) = 10(0)
Multiply: g'(0) = 0
