Answer:
The answer is −2x+y=−4 or 2x−y=4 . Standard form is Ax+Ay=C
Step-by-step explanation:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

Exponential Decay Function
The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.
The equation of the model is:
[tex]M(t)=M_o\cdot(1-r)^t[/tex]
[tex]M(t)=970\cdot(1-0.277)^t[/tex]
Operating:
[tex]M(t)=970\cdot 0.723^t[/tex]
After t=13 minutes the remaining mass is:
[tex]M(13)=970\cdot 0.723^{13}[/tex]
Calculating:
M(13)=14.3 gram
What is the quotient of 6/7 and 3/14
Answer:
6/7 divided by 3/14=4
Step-by-step explanation:
Hope this helps!
Answer: 4
Step-by-step explanation: To divide fractions, you have to switch the operation to multiplication, and multiply the first fraction by the reciprocal of the second fraction. So 6/7 times 14/3. Cross cancel out, so 14 and 7. 7 cancels out to be 1, 14 cancels out to be two. 6 and 3, are the same thing. So in the end you have 2/1 times 2/1 which is 4.

Last month, Sheldon earned $12.80 in interest on a $320 deposit into his bank account. If the interest earned is directly proportional to the amount deposited, how much interest can Sheldon expect next month if he deposits $830?
Answer:
[tex]x=\$ 32.20[/tex]
Step-by-step explanation:
[tex]\frac{12.80}{320}=\frac{x}{830} \therefore 320x=830\times12.80[/tex]
[tex]x=\$ 32.20[/tex]
Answer:
the answer is $487.20 if he expects to deposits $830
