Answer:
$10
Step-by-step explanation:
Investment 1- simple interest
Investment 2- compound interest
- Gain= 4000*(1.05²-1)= $410
The difference:
Answer:
3x^6+x^5-x^4-6x^3+x^2+3x-1
Step-by-step explanation:
The slope is 4 and the y-intercept is
Step-by-step explanation:
The general form of a linear equation is Ax + By + C = 0, where
- A is the coefficient of x
- B is the coefficient of y
- C is the numerical term
- A, B, and C are integers
- The slope of the line =
- The y-intercept =
∵ The linear equation is 0 = 2 - 3y + 12x
- Switch the two sides and arrange the terms as the general
form above
∴ 12x - 3y + 3 = 0
∴ A = 12
∴ B = -3
∴ C = 2
∵ The slope of the line =
- Substitute A by 12 and B by -3
∴ The slope of the line =
∴ The slope of the line = 4
∵ The y-intercept =
- Substitute C by 2 and B by -3
∴ The y-intercept =
∴ The y-intercept =
The slope is 4 and the y-intercept is
