Given f(x) = 21 - 1, complete the missing values in the table

Anna11 [10]

Answer:

first one is f(x)=-5

second one is f(x)=7

third one is x=-3

4th one is x=0

5th one is f(x)=1

6th one is x=-4

Step-by-step explanation:

first one. plug in x as -2:

f(x)=2*-2-1=-4-1=-5

second one is the same way:

f(x)=4*2-1=8-1=7

third one is a different one:

2x-1=-7

2x=-6

x=-3

4th one is the same way:

2x-1=-1

2x=0

x=0

5th way is the same thing as previous:

f(x)=2*1-1=2-1=1

Finally, the 6th one is the same thing as the 4th one:

2x-1=-9

2x=-8

x=-4

Done!

Problem 2.9 a runner completes the 200-meter dash with a time of 20.19 seconds. part a what was the runner's average speed in me

Elina [12.6K]

Answer:

Average speed = 9.91 m/s

Explanation :

Total distance covered by a runner = 200 m

Time taken to complete this distance = 20.19 sec

We need to find the average of runner speed in meter/sec

We use the speed, distance, time formula

$speed = \frac{distance}{time}$

speed = $\frac{200}{20.19}$

Average speed = 9.91 m/s

that's the final answer.

I hope it will help you.

Evaluate the expression 4x/2x for x=3

gayaneshka [121]

Hey there!

If $\bold{x=3}$ then your equation becomes $\downarrow$

$\bold{\frac{4(3)}{2(3)}}$

$\bold{4\times3=12}$
$\bold{2\times3=6\\}$
Your equation should becomes: $\bold{\frac{12}{6}=2}$
$\boxed{\boxed{\bold{Answer:2}}}$

Good luck on your assignment and enjoy your day
