A line with a slope of -4 passes through the point (0, 0). What is its equation in
Dahasolnce [82]

Answer: y = -4x

Step-by-step explanation: You would use the formula y = mx + b to solve your problem. When you plug the numbers in, you get y = -4x. There would be no "+ b" because in this case, the y-intercept (b) is equal to zero. Therefore, you would not need to write "y = -4x + 0" because that would not be the equation in its simplest form.

What is the slope of the line that passes through (10,0) and is parallel to y = (1/2)x + 3?
faltersainse [42]
Y=1/2x+c
0=1/2 (10)+c
0=5+c
c=-5

the equation is y=1/2x+5
the slope is the same since these two lines are parallel

Solving systems of linear inequalities
PIT_PIT [208]

Answer:

YES. (2, 7) is a solution of the system.

Step-by-step explanation:

System of linear inequalities has been given as,

y ≥ -x + 1 --------(1)

y < 4x + 2 ------(2)

If (2, 7) is a solution of the given system of inequalities, it will satisfy both the inequalities.

By substituting the coordinates of point (2, 7) in inequality (1),

7 ≥ -2 + 1

7 ≥ -1

True.

By substituting the coordinates of point (2, 7) in inequality (2),

7 < 4(2) + 1

7 < 9

True.

Therefore, point (2, 7) lie in the solution area of system of inequalities.

YES. (2, 7) is a solution of the system.

What is the median for the following set of data? 2, 3, 6, 8, 9, 10, 11
Inessa05 [86]

Answer:

The median value will be 8.

Step-by-step explanation:

The simplest way to think of a median is as a sort of "middle" value. We want to arrange our numbers from lowest to highest, then select the one in the middle. Here is another example:

3, 5, 2, 7, 3, 9, 1, 4, 7

The first step is to order these numbers from lowest to highest, like so:

1, 2, 3, 3, 4, 5, 7, 7, 9

The number in the middle of this set is 4.

The problem you have presented, as well as the above example, both deal with an odd amount of numbers. Your problem has seven numbers, and the example I gave has nine. For any odd amount of numbers, the median is the value in the middle. But what about an even amount of numbers?

Consider:

9, 4, 3, 7

Let's rearrange this:

3, 4, 7, 9

Now, there will be two "middle" values: 4 and 7. The median value will be the average of these two values:

\text{median} = \frac{4 + 7}{2} = \frac{11}{2} = 5.5

I hope that helps!
