Answer: x=−9/4

Step-by-step explanation:

Let's solve your equation step-by-step.

−2(x+14)+1=5

Step 1: Simplify both sides of the equation.

−2(x+14)+1=5(−2)(x)+(−2)(14)+1=5(Distribute)−2x+

Answer:

x = -2 1/4

Step-by-step explanation:

-2(x + 1/4) + 1 = 5

-2x - 1/2 + 1 = 5

-2x + 1/2 = 5

-2x = 5 - 1/2

-2x = 4 1/2

-x = 2 1/4

x = -2 1/4

Hope this helps!

Let me know if I'm wrong :)

Please tell me the answer quick

To compare these numbers, you must first put them into one format.  Since you have mixed numbers, you may have to find and use the LCD.

-2.5, 1/5, 10, -12/4, 18/5, 10 could be simplified somewhat immediately:

-2.5, 1/5, 10, -3, (3 3/5)   This set of numbers is simple enough so that you could rearrange them in ascending order mentally:

-3, -2.5, 1/5, (3 3/5), 10

In this case the number of elements in this set is odd, so all you have to do is to select the MIDDLE element:  1/5.

The median is 1/5.

You MUST learn this procedure (arranging the set elements in ascending order and selecting the middle element) so that you can apply it yourself.

Write an equation in point-slope form for the line through the given point that has the given slope.
valkas [14]

Answer:

y=mx+b is the formula. So -8=-3x+5 would be the answer..

since (x,y) just substitute these numbers you have it into the formulas... Take y from (5,-8) and place it into y=mx+b. Next take the slope which is -3. And then since its a postive number we <em>add</em> are x from (x,y). -8=-3x+5. We also add x next to the slope (-3) becuase we are trying to solve for x. And we <em>always</em> put it next to the slope. Hope this helps!
