The points on the number line are -6 and 2.

2 - -6 = 4

2 + 6 = 4

A is not the answer.

--6 - 2 = 8

+6 - 2 = 4

B may be the answer.

-6 - 2 = -8

C is not the answer.

-2 - -6 = 4

-2 + 6 = 4

D is not the answer.

<h3>The answer is B) The value of -a - 6 is positive.</h3>

Let me know if this is the correct answer. :)

wind resistance varies jointly as an objects surface area and velocity. if an object traveling at 55 miles per hour with a surfa

nikdorinn [45]

Answer:

25 miles per hour

Step-by-step explanation:

Given

$W = Wind\ resistance$

$A = Surface\ Area$

$V = Velocity$

The joint variation can be represented as:

$W\ \alpha\ A*V$

Where:

$V = 55; A = 20; W = 220$

Required

Find V, when: $A = 55; W = 275$

We have:

$W\ \alpha\ A*V$

Express as an equation

$W= k *A*V$

Where k is the constant of variation

Make k the subject

$k = \frac{W}{A*V}$

When: $V = 55; A = 20; W = 220$

We have:

$k = \frac{220}{20 *55 }$

$k = \frac{220}{1100}$

$k = 0.2$

When: $A = 55; W = 275$

We have:

$k = \frac{W}{A*V}$

Substitute: $A = 55; W = 275$ and $k = 0.2$

$0.2 = \frac{275}{55 * V}$

Make V the subject

$V= \frac{275}{55 * 0.2}$

$V= \frac{275}{11}$

$V= 25$

Write the equation of the line parallel to the

kakasveta [241]

Answer:

x=-7

Step-by-step explanation:

If a line is parallel to the y-axis, then it is vertical because the y-axis is vertical.

A vertical line is in the form of x=a number.

Since the line we are looking for is 7 units to the left of the y-axis, then the line is x=-7. -7 is 7 units left of 0.

7 units right would have been x=7.
