Point a (–4,1) is in the standard ( x , y ) co ordinate pl an
ser-zykov [4K]
The line x = 2 is vertical. This means that ab is horizontal since they are perpendicular. So, the y coordinate of b must be 1.

If x = 2 bisects ab, then a and b are equal distances from x = 2. 

a is 2 - (-4) = 6 units away from x = 2, so b must be 6 units away in the other direction. The x coordinate of b is 6 + 2 = 8.

The coordinate of b is (8, 1)

Which of the following is the missing reason? Statements Reasons two thirds times x plus 7 equals negative 5 Given 2x 21 = â’15
pentagon [3]

The correct option is B. Distributive property

Given,

\frac{2}{3} x+7=-5\\

On solving the above equation,

multiplying both sides by 3 we, get

2x+21=-15

now subtracting 21 from both the sides,

2x=-36\\

dividing both the sides by 2 we get,

x=-18

Since in the above steps we follow all the giving property except the distributive property.

Hence the correct option is B. Distributive property.

A shipping container will be used to transport several 100-kilogram crates across the country by rail. The greatest weight that
lora16 [44]

Answer:

x ≤ 204 crates

Step-by-step explanation:

Greatest weight of the container = 27500 kilograms

Weight of other shipment = 7100 kilograms

Weight of crates = 100 kilogram

x = number of 100 kilogram crates that can be loaded into the shipping container.

The inequality:

27500 ≤ 7100 + 100x

27500 - 7100 ≤ 100x

20,400 ≤ 100x

x ≤ 20,400 / 100

x ≤ 204 crates of 100 kilogram
