Answer:
5%
Step-by-step explanation:
You want to find r when ...
I = Prt
is equal to P and t=20.
P = Pr·20 . . . . fill in the problem values
1/20 = r = 0.05 = 5% . . . . divide by 20P
The simple interest rate is 5%.
Answer:
expand (a + 7) * 2: 2a + 14
Step-by-step explanation:
(a + 7) * 2
= 2 ( a + 7)
apply the distributive law: a(b + c) = ab + ac
a = 2, b = a, c = 7
= 2a + 2 * 7
multiply the numbers: 2 * 7 = 14
= 2a + 14
Answer:
- 5x - 3y = 9 (Example)
- y = 1/2x - 3 (Non-Example)
- 2x + 3y = 0 (Example)
- x + y = 1 (Example)
- x = 6y (Non-Example)
- y = x - 2 (Non-example)
Step-by-step explanation:
Standard form of the equation is given by:
Ax + By = C
Where
- A, B and C are constants which must be Integers. A should always be positive.
Considering the definition, we can identify the examples and non-examples of standard from of a linear equation.
<h3>
5x - 3y = 9</h3>
- In a form of Ax + By = C
- A,B and C are constants
- A=5 is positive
It is an EXAMPLE of standard form of linear function
<h3>
</h3><h3>
y = 1/2x - 3</h3>
- Not in the form of Ax + By =C
NON-EXAMPLE
<h3>
</h3><h3>
2x + 3y = 0</h3>
- In a form of Ax + By = C
- A,B and C are constants
- A=5 is positive
It is an EXAMPLE of standard form of linear function
<h3>
</h3><h3>
x + y = 1</h3>
- In a form of Ax + By = C
- A,B and C are constants
- A=5 is positive
It is an EXAMPLE of standard form of linear function
<h3>
</h3><h3>
x = 6y</h3>
- Not in the form of Ax + By =C
NON-EXAMPLE
<h3>
</h3><h3>
y = x - 2</h3>
- Not in the form of Ax + By =C
NON-EXAMPLE
