Answer:

5/4 would not fit with the other 3.

Step-by-step explanation:

This is because it is an improper fraction, which is a fraction which is bigger than the value 1. The rest are all less than 1.

Can someone solve this for me???

kolezko [41]

Answer:

Part A: x^2 + 5x - 8

Part B: 5x^3 + 3x^2 - 6x + 5

Step-by-step explanation:

Part A:

To find the total of side 1 and 2, add the two expressions which represent each side. Combine like terms to simplify.

3x^2 − 2x − 5 + (7x - 2x^2 − 3)

3x^2 - 2x^2 -2x + 7x -5 + -3

x^2 + 5x - 8

Part B:

To solve for the third side of a triangle using its perimeter, subtract the lengths of two of its sides from its perimeter. The perimeter is 5x^3 + 4x^2 − x − 3. Subtract 3x^2 − 2x − 5 and 7x - 2x^2 − 3. The remaining expression is the third side. Combine like terms to simplify.

5x^3 + 4x^2 − x − 3 - (3x^2 − 2x − 5) - (7x - 2x^2 − 3)

5x^3 + 4x^2 - x - 3 - 3x^2 + 2x + 5 - 7x + 2x^2 + 3

5x^3 + (4x^2 -3x^2 + 2x^2) + (-x + 2x - 7x) + (-3 + 5 + 3)

5x^3 + 3x^2 - 6x + 5

graph the solution to the following system of inequalities y<-2x+7, y greater than or equal to 2x - 3

Alex777 [14]

Answer:

See attached diagram

Step-by-step explanation:

Graph the solution of the inequality $y$ First, draw the dotted line $y=-2x+7$ (dotted because the sign of the inequality is <). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (red part on the diagram).

Graph the solution of the inequality $y\ge 2x-3.$ First, draw the solid line $y=2x-3$ (solid because the sign of the inequality is ≥). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (blue part on the diagram).
