Can someone answer this? It’s 9th grade algebra

Answer:

B. 1/81

Step-by-step explanation:

f(-4) = 3(-4)

f(-4) = -12

Hope that helps.

-12,1/243,-64 or 1/81

1/81 would be the correct answer to the equation hope this helps

evaluate the function rule for the given value.

f(x)=3^x for x=-4

-----

f(-4) = 3^(-4)

---

f(-4) = (1/3)^4

---

f(-4) = 1/81

Step-by-step explanation:

7=3x-5-5x

7=3x-5x-5

7=-2x-5

7+5=-2x

12=-2x

x=12/-2

×=-6

Answer:

-6 = x

Step-by-step explanation:

7 = x + 2x - 5 - 5x

~Combine like terms

7 = -2x - 5

~Add 5 to both sides

12 = -2x

~Divide -2 to both sides

-6 = x

Best of Luck!

Hi

Let call X the origninal price.

if it rose of 20 % , it's mean that it' be multiplicate by 1.20

so :

X*1,2 = 25.8

1.2X=25.8

As math is all about method and training, I let you have a try and resolve the equation. If you do not know how, ask in comments section.

The best described compass tool is a metal instrument with two legs-one with a point and one for a pencil option (c) a metal instrument with two legs-one with a point and one for a pencil.

The magnetic field is defined as the field the magnetic materials generate or when an electric charge moves in a field region that generates the magnetic field.

It is given that:

A tool is a compass tool which is an indicating the north direction.

As we know,

The magnetic field is defined as the field the magnetic materials generate.

A metal object with two legs, one for a pencil and one with a tip.

Thus, the best describes compass tool is a metal instrument with two legs-one with a point and one for a pencil option (c) a metal instrument with two legs-one with a point and one for a pencil.

Answer:

what?

Step-by-step explanation:

Answer:

The correct answer is option A. Line DB

Step-by-step explanation:

When you write that M is a line, the sign for this would be a line with arrows on both of its end like this :  <------------>

Now, due to the fact that lines look like this  <------------>, we can cross out option C and D as they both aren't lines but points. Points go like this: ---->

Option B says, "line EB", this can't be true because E corresponds with the letter F, it can't become a line with B hence why the only option true here is choice A.

Answer:

a = dr/c

Step-by-step explanation:

ca = dr

Divide both sides by c. This gets a by itself on the left side.

a = dr/c

Answer: The 2 red lines are parallel and the blue line is transversal

Step-by-step explanation:

The 2 red lines are parallel (align with each other)

The blue line goes thru the other 2 lines meaning its transversal.

Step-by-step explanation:

             =7/12

2)remaining=12/12-7/12

                   =5/12

DOMAIN: [0, +6)

RANGE: (-2.5, +2.5)

REMEMBER THAT THE DOMAIN IS SET ACCORDING TO THE GRAPH’S RELATION TO THE X-AXIS (-X, +X).

REMEMBER THAT THE RANGE IS ISET ACCORDING TO THE GRAPH’S REALTION TO THE Y-AXIS (-Y, +Y).

REMEMBER THAT THE BEST WAY TO APPRECIATE THIS AID TO YOUR LEARNING TO MARK “BRAINLIEST”.

The Answer is:

p=15

5x3=15

So that must mean 15/5=3

Hi! I'm happy to help!

To make this equation easier, we can use the inverse operation, multiplication (instead of division).

p÷5=3

3×5=p

Doing this will give you the same answer, it just makes it easier. 3 times 5 is 15, so p=15

We can double check our answer by putting in 15 for p.

p÷5=3

15÷5=3, this is true, so our answer is correct.

I hope this was helpful, keep learning! :D

Answer: f(-3) = -4

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Given expression

f(n) = 3n + 5

Substitute values into the expression

f(-3) = 3(-3) + 5

Simplify by multiplication

f(-3) = -9 + 5

Simplify by addition

f(-3) = [tex]\boxed{-4}[/tex]

Hope this helps!! :)

Answer:

does the sugar levels matter just bake the da*n cookies man

Answer:

see below:

Step-by-step explanation:

the median will become a larger, different number. The mean will also become a larger number, since it will still be dividing by the same amount of numbers in the equation, only the quantity will become larger. Same with standard deviation. The IQR will change, because the amount of the two numbers you'll be subtracting will end up greater than before.

977.834 can be defined as a rational number. Why? Well, 977.834 is not a non-terminating non-recurring/recurring number. Of it was, then it would have been an irrational number. Now, it can be a real number also because real numbers include all sorts of numbers whether it be fractions, decimals, roots, cubes etc. It's not an integer because integers don't include decimals or fractions numbers. So, the answers or options that are correct are

Answer:

18

Brainliest, please!

Step-by-step explanation:

3^3 + 11 - 10 / 2 x 4 = w

27 + 11 - 10 / 2 x 4 = w

27 + 11 - 5 x 4 = w

27 + 11 - 20 = w

38 - 20 = w

w = 18

Answer:

106

Step-by-step explanation:

a=74

c=?

180-74=106

============================================================

Explanation:

As the hint states at the top, supplementary angles add to 180 degrees

If we glued the angles together, then we'd form a straight line.

angleA+angleC = 180

74+C = 180

C = 180-74

C = 106 degrees

Now to find area it is LxW

7x13=91

So the area of the rectangle is 91 meters squared

Step-by-step explanation:

Answer:

Area=120[tex]cm^{2}[/tex]

Perimeter =44[tex]cm^{2}[/tex]

Step-by-step explanation:

area=length(l)*width(w)    

      =12*10                        

     =120[tex]cm^{2}[/tex]

perimeter=2(length+width)

                =2(12+10)

                =2*22

               =44[tex]cm^{2}[/tex]
