Answer:

Step-by-step explanation:

When you have two opposite numbers on a numberline, that is, a digit that has a negative value and the same digit having a positive value, when you add them together, we would have 0.

i.e. -a + b = 0

In the above options given, the numberline that shows this particular case is the numberline in option D.

In option D numberline, the sum of -1 and +1 equals zero.

The price of a pair of shoes increases from $65 to $81. What is the percent increase to the

andriy [413]

Answer:

Percent increase = 25%

Step-by-step explanation:

Given that:

Old price of shoes = $65

New price of shoes = $81

Difference = 81 - 65

Difference = 16

Percent increase = $\frac{Difference}{Old\ price}*100$

Percent increase = $\frac{16}{65}*100$

Percent increase = 0.246 * 100

Percent increase = 24.6%

Rounding off to nearest whole number

Increase = 25%

Hence,

Percent increase = 25%

Question: What is the volume of the box? Explain how you found your solution.

Vikki [24]

The volume of the box is 100 cubic meter.

Step-by step explanation:

Given data:

Length of the box = 10 m

Width of the box = 5 m

Height of the box = 2 m

To find the volume of the box:

Volume of the box = length × width × height

= 10 m × 5 m × 2 m

= 100 cubic meter

Hence the volume of the box is 100 cubic meter.

Drag each graph to show if the system of linear equations it represents will have no solutions, one solution at (2,6), one solut

hjlf

Answer:

see the explanation

Step-by-step explanation:

Verify each case

Part 1) The graph show two identical lines, then the system has infinitely many solutions

Part 2) The graph show two perpendicular lines.

Remember that the solution of the system is the intersection point both graphs

The intersection point is (2,6)

therefore

The system has one solution at (2,6)

Part 3) The graph show two intersecting lines at (-6,-2)

Remember that the solution of the system is the intersection point both graphs

The intersection point is (-6,-2)

therefore

The system has one solution at (-6,-2)
