Answer:

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 !

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.

Answer:

a/c = a/c

Step-by-step explanation:

That is, if a, b, and c are real numbers such that a = b and c ≠0, then

a/c = a/c

The property state that c≠0 because division by zero does not exist.

The Division Property of Equality says that for every real number a, b, and c, if a = b and c ≠ 0, then a/c = b/c.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

When "a" and "b" are divided, the outcome of the division is the amount of "a" that each of the "b" items will receive.

Therefore, if there are 20 pens and 5 students, the amount of mangoes that each student would receive is 20 ÷ 5 or 4, or 4 pens.

When a number is divided, it can be thought of as being divided equally into a total of x parts, where x is the number of parts into which the given number is divided.

The Division Property of Equality says that for every real number a, b, and c

if a = b and c ≠ 0, then a/c = b/c.

The property state that c ≠ 0 because division by zero does not exist.

Answer:

Step-by-step explanation:

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 ;)

Answer:im not good at explanation but i think its -1

Step-by-step explanation:

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

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: 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:

10x-5

Step-by-step explanation:

You subtract 15x-5=10x. Then you do -7+2. The 7 is negative . So it would be -7 plus two. So it would equal -5. So it's 10x-5
