A 2 pound box of salt sells for $.89 and a 5 pound box sells for 2.09. What is the linear equation for this?

castortr0y [4]

Y = ax + b;

0.89 = a * 2 + b and 2.09 = a * 5 + b =>
=> 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40;
b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09;

y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.

What is the area of this question.

frez [133]

The area of a circle is \pi r^2, where r is the radius of the circle. The diameter of a circle is the length of a line that passes through the center of the circle and stops at the perimeter of circle. The radius of a circle is half the diameter. Divide the diameter by 2 to find the radius.
1. 2.8 m / 2 = 1.4 m
2 . $\pi (1.2m)^2$ : Plug in the value we just found for r.
3. $\pi 1.44m^2$ : Use the order of operations (PEMDAS).
4. $\pi * 1.44m^2 = ~4.52 m^2$
The area of the circle is equal to $4.52 m^2.$

am • an = am + n, where a is a real number and m and n are integers Use the product of powers property to simplify the expressio

Maru [420]

1. Take out the constants
-(2 x 3 x 4 x 2)xxyy^3
2. Simplify 2 x 3 x 4 x 2 to 48
-48xxyy^3
3. Use Product Rule: x^ax^b = x^a+b
-48x^1+1y^1+3
4. Simplify 1 + 1 to 2
-48x^2y^1+3
5. Simplify 1 + 3 to 4
-48x^2y^4
