Let's say you had something in the form Ax+By > C
Solving for y would get it into the form y > mx+b only if B is positive.
If B were negative, then the sign would flip and you'd have y < mx+b
For y > mx+b, you shade above the boundary line and y < mx+b has you shade below the boundary line.
The boundary line itself is y = mx+b which goes through two points. Use a solid line if there is an "or equal to" as part of the inequality sign. Otherwise, use a dashed boundary line.
---------------------------
Examples:
- x+y > 10 solves to y > -x+10. The boundary line is dashed and it goes through (0,10) and (10,0). Shade above the boundary line.
- solves to . The boundary line y = -2x+4 goes through (0,4) and (2,0). This boundary line is solid. Shade below the boundary line
- x-y > 7 solves to y < x-7. Note the sign flip. The boundary is dashed and it goes through (0,-7) and (7,0). Shade below the boundary line.
An online grapher such as desmos will quickly let you graph any inequality so you can check your work.
Make them the same i think
The numbers of gallons bought every stop are extraneous...you can ignore them. Add 1.68, 1.76 and 1.65 together and divide the total by three. The average is 1.69
If you need to find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem if you know the length of the other two sides. Square the length of the 2 sides, called a and b, then add them together. Take the square root of the result to get the hypotenuse
Answer:
5x+10y+5z.
Step-by-step explanation:
The given expression is
We need to find the equivalent expression by using the distributive property.
By using the distributive property, the given expression can be written as
Therefore, the required expression is 5x+10y+5z.
