Answer:

C=6p

Step-by-step explanation:

The cost (c) will be by itself since that is the answer you are looking for. 6p is grouped together because for every pound you pay $6. For example if you had 2 pounds of chocolate. You would multiple $6 by 2 and your cost would equal $12

Answer:

c=6p

Step-by-step explanation:

c= the cost

p= pounds of chololate

Answer:

- 180

Step-by-step explanation:

[tex] - 6 \times 1 \times 30[/tex]

Multiply :

[tex] - 6 \times 1 = - 6 \\ - 6 \times 30 = - 180[/tex]

Answer:

Step-by-step explanation:

1). If a point C is lying on a line segment RB,

   Then RB = RC + CB

   Since, RB = 45, CB = 3x - 12 and RC = 2x + 9

   45 = (2x + 9) + (3x - 12)

   45 = (2x + 3x) - 3

   48 = 5x

   x = [tex]\frac{48}{5}[/tex]

   x = 9.6

2). Since, RC = 2x + 9

    RC = 2(9.6) + 9

          = 19.2 + 9

          = 28.2 units

3). Distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

  d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

  Distance between the points A(2, -2) and D(-2, 2) will be,

 [tex]AD=\sqrt{(2+2)^2+(-2-2)^2}[/tex]  

         = [tex]\sqrt{16+16}[/tex]

         = [tex]4\sqrt{2}[/tex]  

         = 5.657

         ≈ 5.66 units

Answer:

O 72 in

Step-by-step explanation:

Answer:

x = -3

Step-by-step explanation:

Step 1: Add 1.4 to both sides.

0.7x − 1.4 + 1.4 = −3.5 + 1.4

0.7x = −2.1

Step 2: Divide both sides by 0.7.

0.7x/0.7 = −2.1/0.7

x= −3

Hope this helps

Answer:

x= -3

Step-by-step explanation:

add 1.4 on both sides giving you

0.7x/0.7 = -2.1/0.7 and 0.7x cancels out leaving you with -2.1 divided by 0.7

when you divide you Get  -3

Answer:

c    lololololo    

Step-by-step explanation:

Answer:

x =5

Step-by-step explanation:

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

Given the points A(2, x) , B(x, 8) and AB = 3√2

On substituting the given values into the formula;

AB = √(x-2)²+(8-x)²

3√2= √(x-2)²+(8-x)²

square both sides

(3√2)²= (x-2)²+(8-x)²

18 = (x-2)²+(8-x)²

expand

18 = x²-4x+4+64-16x+x²

18 = 2x²-20x+68

2x²-20x+68-18 = 0

2x²-20x+50 = 0

x²-10x+25 = 0

Factorize

x²-5x-5x+16 = 0

x(x-5)-5(x-5) = 0

(x-5)(x-5) = 0

x-5 = 0 an x-5 = 0

x = 5

Answer:

(-1/2,15/2)

Step-by-step explanation:

let(-4,7)=(x1,y1)

(3,8)=(x2,y2)

Then,

Using midpoint formula,

Midpoint(x,y)=((x1+x2)/2,(y1+y2)/2)

=((-4+3)/2,(7+8)/2)

=(-1/2,15/2)

Thus,midpoint(x,y)=(-1/2,15/2)

Answer:

M=-8

Step-by-step explanation:

21+6m=3(m−1)

Step 1: Simplify both sides of the equation.

21+6m=3(m−1)

21+6m=(3)(m)+(3)(−1)(Distribute)

21+6m=3m+−3

6m+21=3m−3

Step 2: Subtract 3m from both sides.

6m+21−3m=3m−3−3m

3m+21=−3

Step 3: Subtract 21 from both sides.

3m+21−21=−3−21

3m=−24

Step 4: Divide both sides by 3.

3m/3=-24/3

M=-8

Answer:

m = - 8

Step-by-step explanation:

Given

21 + 6m = 3(m - 1) ← distribute

21 + 6m = 3m - 3 ( subtract 3m from both sides )

21 + 3m = - 3 ( subtract 21 from both sides )

3m = - 24 ( divide both sides by 3 )

m = - 8

Answer:

-22

I'm assuming you don't need an explanation because this is just a short answer question.

Answer:

t does not matter if the two numbers are the same for multiplication or division. 4. ( ÷ ) To divide two fractions, take the second fraction, and flip it so that the top number is now on the bottom and vice versa, then multiply the two fractions together like you would for number 3.

Answer:

The point (-2,0) is on the line: False

The point (0,-2) is on the line: True

The graph represents the equation 2x-2y=4: True

The graph represents the equation 2x+2y=4: False

Step-by-step explanation:

(-2,0) is not on the line, but (0,-2) is.

In order to find the answer to the last two, you must put the equation in y=mx+b form. The third question in y=mx+b form is y=x-2.

2x-2y=4

-2y=-2x+4

y=x-2, That is the equation.

The fourth question in y=mx+b form is y=-x+2.

2x+2y=4

2y=-2x+4

y=-x+2, That is not the equation.

Answer:

C

Step-by-step explanation:

Answer:

3x+10

Step-by-step explanation:

Plug n(x) into the x of the m(x) and the answer is m(n(x)).

m(x) = 3x - 2

n(x) = x + 4

Plug in n(x) to m(x) as shown here

m(n(x)) = 3(x + 4) - 2

distribute the 3

m(n(x)) = 3x + 12 - 2

simplify

m(n(x))= 3x + 10

Answer: 3

Explanation:

3^2 + 12 - 6 = 5^2 - 13 + (?)

start with 3^2 or 3x3 giving us 9 then we add 12 to it 9+12=21 subtract 6. 21-6=15 then we have to make the next part equal 15 so we start off by seeing how much we have so 5^2 or 5x5=25 then subtract 25-13=12 so that means we have to see what we need to add to this to make it 15 which is 3 so that means your answer is 3

3^2 + 12 - 6 = 5^2 - 13 + 3

Answer:Overall, the steps for algebraically finding the range of a function are:

Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).

Find the domain of g(y), and this will be the range of f(x).

If you can't seem to solve for x, then try graphing the function to find the range.
