Which equation represents a line which is parallel to the line 2x+y=-8?A. y=− 1/2 x−4B. y=−2x+5C. y=2x+3D. y= 1/2x+2
katrin2010 [14]

Two lines that are parallel have the same slope. In its slope-intersect form, we can write the equation of a line with slope m and y-intercept b as:

y=mx+b

Step 1

Write the given equation in slope-intercept form and identify its slope m.

\begin{gathered} 2x+y=-8 \\  \\ 2x+y-2x=-2x-8 \\  \\ y=-2x-8 \end{gathered}

Thus:

m=-2

Step 2

Find the equation with the same slope m = -2. We need to identify which of them has -2 multiplying the variable x.

Answer

From the given options, the only one with the same slope m = -2, therefore parallel to the given line, is:

y=-2x+5\text{      (option B)}

Form a union for the following sets. K = {2, 3, 5, 8} L = {3, 5, 7}
Crazy boy [7]

Answer:

Given the sets:

K = {2, 3, 5, 8} and L = {3, 5, 7}

To find the union of K and L i.e, K \cup L

Union set defined as the union (denoted by U) of a collection of sets is the set of all elements in the collection.

K \cup L = \{2,3,5,8\} \cup \{3,5,7\} =\{2,3,5,7,8\}

Therefore, union for the following sets is, {2,3,5,7,8}.

Nana76 [90]

Answer:

50%

Step-by-step explanation:

29 right and 29 wrong. 29+29=58

Divide 29 by 58 and you get .5

Move the decimal over two to the right, and there’s the 50%.

You could also multiply .5 by 100 and you’ll still get 50!
