Answer:

infinite solutions

Step-by-step explanation:

x+6+8=2x-x+14

x+6+8=x+14

x+14=x+14

14=14

or

x=x

plug in any number

2+6+8=2(2)-2+14

16=16

another example

8+6+8=2(8)-8=14

22=22

What is the first step in solving the quadratic equation x2 = 9/16
anygoal [31]
The equation is \displaystyle{ x^2= \frac{9}{16}. We can rewrite the equation as:

                                    \displaystyle{ x^2= (\frac{3}{4})^2.

Our next step here is to take the square root of both sides, remembering that \sqrt{x^2}=|x|.

Thus, we have \displaystyle{ |x|= \frac{3}{4}. Our final step is solving the absolute value equation, which yields:

\displaystyle{ x= \frac{3}{4} or \displaystyle{ x= -\frac{3}{4}.


 Solution set: { -\frac{3}{4}, \frac{3}{4} }

Gambling at a slot machine is an example of which reinforcement schedule?
gogolik [260]

Answer:

d. Variable ratio

Step-by-step explanation:

We are asked to determine that gambling at a slot machine is an example of which reinforcement schedule.

Let us see our given choices one by one.

a. Fixed ratio

We know that in fixed ratio schedule, reinforcement is delivered after the completion of a number of responses. An example of fixed ratio is a reward to every 6th response.

b. Fixed interval

We know that in fixed interval schedule the first response is rewarded only after a specified amount of time has elapsed. An example of fixed interval schedule is weekly paycheck.

c. Variable interval

We know that in variable interval schedule, the reinforcement is delivered at changing and unpredictable intervals of time.

d. Variable ratio

In variable ratio schedule, a response is reinforced after an unpredictable number of responses. Gambling and lottery are examples of variable ratio.

Therefore, option 'd' is the correct choice.

If the length of AC equals 18, what is the length of the midsection DE
Free_Kalibri [48]

Answer:

The length of the midsegment is 9 ⇒ (B)

Step-by-step explanation:

In a triangle,

  • The midsegment is the segment which joining the midpoints of two opposite sides of it
  • The length of the midsegment is half the length of the third side in the triangle which opposite to it

<em>Let us use this rule to solve our question</em>

In Δ AC

∵ DE is the midsegment of it

∵ DE is opposite to the side AC

∴ The length of DE = 1/2 the length of AC

∵ The length of AC = 18

∴ The length of DE = 1/2 × 18

∴ The length of DE = 9

∴ The length of the midsegment is 9

The correct answer is B

mixas84 [53]

Answer:

B.

Step-by-step explanation:

If you rearrange the equation in b, you get

y=5(x-3)+15

This means that your f(1) is equal to f(3), or 15, and for each additional month, it increases by 5, which is what the table shows.
