Answer:

We have to graph the function g(x) which is given as:

g(x)=  x when x<2

 and -3 when x ≥2.

Clearly after looking at the function we see that the function is not continuous since we find the continuity at x=2 as follows.

Left hand limitat 2:

g(2-h)=lim h→0 2-h

        =2-0=2

Also right hand limit at x=2 is:

g(2+h)=lim h→0 (2+h)

          = 2+0=2

Also g(2)= -3.

As:

Left hand limit= Right hand limit but is not equal to function's value at that point.

Hence, the function is discontinuous at x=2.

so for x<2 we will get a graph of a line y=x.

and for x≥2 we will get a straight line y=-3 parallel to the domain.

Ronald ran 6 laps in 12 minutes. Which ratio can be used to find the number of laps that Ronald ran in 1 minute?
Sergio039 [100]

Answer:

0.5:1

Step-by-step explanation:

laps:minutes

So we can find how much Ronald runs in 2 minutes, by dividing 6:12 (or 6/12) by 6. This will give you 1:2 (One lap = 2 minutes).

But you're looking for 1 minute, so with 1:2, you have to divide them by 1/2, so it will be 0.5:1.

For the equations given below, which statement is true?
allochka39001 [22]

Answer: C. The equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.

Step-by-step explanation:

You know that the first equation is:

-3x-8=19

And the second equation is:

-3x-2=25

According to the Addition property of equality:

If a=b; then a+c=b+c

Then, you can add 6 to both sides of the first equation to keep it balanced. Then, you get:

-3x-8=19\\\\-3x-8+(6)=19+(6)

-3x-2=25

Therefore, you can observe that the second equation can be obtained by adding 6 to both sides of the first equation, therefore, the equations have the same solution.

If you want to verify this, you can solve for "x" from both equations:

- First equation:

-3x-8=19\\\\-3x=19+8\\\\x=\frac{27}{-3}\\\\x=-9

- Second equation:

-3x-2=25\\\\-3x=25+2\\\\x=\frac{27}{-3}\\\\x=-9
