1/9 * 54/1 = 54/9.

Answer:
It cost $0.91 10 years ago.
It takes 10.24 years for the cost of bread to double.
Step-by-step explanation:
The equation for the price of bread after t years has the following format:
In which P(0) is the current price, and r is the inflation rate, as a decimal.
If we want to find the price for example, 10 years ago, we find P(-10).
Inflation is at a rate of 7% per year. Evan's favorite bread now costs $1.79.
This means that . So
What did it cost 10 years ago?
It cost $0.91 10 years ago.
How long before the cost of the bread doubles?
This is t for which P(t) = 2P(0) = 2*1.79. So
It takes 10.24 years for the cost of bread to double.
The equation of the line in standard form is 3x - 5y = 26
Step-by-step explanation:
Let us revise the forms of the linear equation
- The slope intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept
- The point-slope form is , where m is the slope of the line and is a point on the line
- The standard form is Ax + By = C, where A, B, and C are constant
- The general form is Ax + By + C = 0, where A, B, and C are integers
∵ The line passes through point (2 , -4)
∵ The slope of the line is
- Let us using the point-slope form and then change it to the
standard form
∵ = 2 and = -4
∵ m =
- Substitute these values in the form of the equation below
∵
∴
∴
Let us change it to standard form
- Multiply each side my 5 to cancel the denominator in the
right hand side
∴ 5(y) + 5(4) = 3(x - 2)
- Simplify the two sides
∴ 5y + 20 = 3x - 6
- Add 6 to both sides
∴ 5y + 26 = 3x
- Subtract 5y from both sides
∴ 26 = 3x - 5y
- Switch the two sides
∴ 3x - 5y = 26
The equation of the line in standard form is 3x - 5y = 26

2x * 3x = 6x^2
6x^2
2x * 3 = 6x
6x^2 + 6x
5 * 3x = 15x
6x^2 + 6x + 15x
6x^2 + 21x
5 * 3 = 15
6x^2 + 21x + 15
The answer is 6x^2 + 21x + 15.
First you want to find a multiple that's very close to 28. It's 24, so subtract 28-24 which is 4. 4 biscuits are left.
Hope that helped:)
