K is the midpoint of JL. JK = 2x + 5 and JL = 50.
To solve for x, Steve sets up the following equation: 2x + 5 = 50
Explain the error in Steve's equation.

Answer: Domain is [tex][0,\infty)[/tex] and range is [0,4000].

Step-by-step explanation:

It is given that, the set of ordered pairs (t,d), where

t = the time in seconds after  someone jumps out of a plane at  4000 meters to go skydiving

d = is the displacement above the  ground.

It means t is independent variable and it is represented on the x-axis.

d is dependent variable and it is represented on the y-axis.

We need to find the domain and Range.

Domain is the set of input values.

Here, input is time and time can not be negative.

Domain [tex]=0\leq t=[0,\infty)[/tex]

Range is the set of output values.

Here, output is displacement above the  ground which can not be negative or more than 4000 meters.

Range [tex]=0\leq d\leq 4000=[0,4000][/tex]

Therefore, domain is [tex][0,\infty)[/tex] and range is [0,4000].

Answer:

1. 5/10

Step-by-step explanation:

Since the options are in fractions, you have to mave 0.5 into a fraction. It is 5 tenths so 5/10 which is 1/2.

The first one is 5/10

1 x 5 = 5

2x 5 =10

So this is equivalent Since there is only one answer, you don't have to try out the rest, thankfully ;)

Hopw this helps :)

Answer:

1.5/10 is the answer

Answer:

w>24

Step-by-step explanation:

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

20<5/6w

Answer: x>24

Step-by-step explanation:

To solve the inequality, we want to isolate w.

[tex]20<\frac{5}{6}w[/tex]             [multiply both sides by 6/5]

[tex]w>24[/tex]

Now, we know that w>24 or 24<w.

x=-9/13

Step-by-step explanation:

x+9=-12x

13x=-9

x=-9/13

please mark it as brainliast

x = - 9/13

Hi there !

x + 9 = - 12x

     →      ←

x + 12x = - 9

13x = - 9

x = - 9/13

Good luck !

Step-by-step explanation:

Since it is an equal sign you want to know when the will have the same amount of money. Also, the person who has $90 must save $9 a week as well because both those numbers are on the same side of the equation and vice versa.

The final temperature is -3 Degrees.

Answer:

73.3

Step-by-step explanation:

50mi/h * 5280ft/mi * 1h/3600s = 220/3 = 73.3 ft/s

Answer:

73 1/3 feet per second

Step-by-step explanation:

50 miles per hour

50*5280/3600 = 73 1/3 feet per second

x^2 = 81/100

Let's take the square root of each side

x = 0.9 and -0.9

Answer:X=3

Step-by-step explanation:We simplify the equation to the form, which is simple to understand  

7+x-(3+32/8)=3

Simplifying:

7+x-(3+4)=3

Simplifying terms in parentheses

7+x-(+7)=3

Remove unnecessary parentheses

7+x-7=3

We move all terms containing x to the left and all other terms to the right.  

+1x=+3-7+7

We simplify left and right side of the equation.  

+1x=+3

We divide both sides of the equation by 1 to get x.  

x=3

Hi there!

Your answer is 15

Step-by-step explanation:

3y+17=62

Step 1 : isolate y by subtracting 17 from both sides.

3y= 62-17

3y = 45

Step 2: Divide out the 3 so you have 1y.

3y=45

Answer: A Person's age is usually considered a discrete variable.

Step-by-step explanation: lets say a person was born in November 2000 and the date is currently September 2020 if asked their age the person would say 19 because they have not turned 20 yet. therefore no matter what date anytime between their 19th birthday up until their 20th birthday they would say they are 19 making age a discrete variable.

Answer:

square roots

quadratic formula

factoring

complete the square

Step-by-step explanation:

1. In the first one, we can divide both sides by -2 and then square root it, getting x^2 = -98 so x = 7i \sqrt(2).

2. We can use the quadratic formula to find out the second one.

3. We can factor 4x^2 - 21x - 18 = 0 and get (x + 6)(4x - 3).

4. In the last one, we can complete the square, getting (x + 9)^2 + 16.
