Sadie has $1 worth of nickels and dimes. She has twice as many nickels as dimes. Write a system of equations that could be used to determine the number of nickels and the number of dimes that Sadie has. Define the variables that you use to write the system.

Answer:

Step-by-step explanation:

well remember that the equation format is y=mx+b

y=2/3-2

Answer:

y=2/3x-2

Step-by-step explanation:

Answer:

Given, x−x1=5

Squaring both the sides,

⇒(x−x1)2=52

⇒x2+x21−2(x)(x1)=25

⇒x2+x21=25+2

⇒x2+x21=27

Now,

x3−x31

=(x−x1)[(x)2+(x1)2+(x)(x1)]

=5(27+1)

=140

9514 1404 393

Answer:

  322

Step-by-step explanation:

Consider the cube ...

  (a +b)³ = a³ +3a²b +3ab² +b³

  = a³ +b³ +3ab(a+b)

Now, for a=x and b=1/x, we have ...

  (x +1/x)³ = x³ +1/x³ +3(x)(1/x)(x +1/x)

Using the known value for x+1/x, this is ...

  7³ = x³ +1/x³ +3(7)

  x³ +1/x³ = 7³ -3·7 = 343 -21

  x³ +1/x³ = 322

The slope intercept form is y=mx+c, So y= -5/6x + 4 is in slope intercept form.

The general equation of slope intercept form is y=mx+c

where m is the slope and c is the y intercept

The given equation is y= -5/6x + 4, we have to check whether the given equation in slope intercept  form or not.

The given equation is y= -5/6x + 4...(1)

We know that general equation of slope intercept form is y=mx+c...(2)

As we compare equations (1) and (2), we find that equation (1) in the form of (2). so y= -5/6x + 4 is in slope intercept form.

Therefore y= -5/6x + 4 is in slope intercept form.

Answer:

∠ 1 = ∠ 3 = 33°

Step-by-step explanation:

∠ 3 and ∠ 6 are same- side interior angles and are supplementary , thus

∠ 3 + ∠ 6 = 180° , that is

∠ 3 + 147° = 180° ( subtract 147° from both sides )

∠ 3 = 33°

∠ 1 and ∠ 3 are vertical angles and congruent, thus

∠ 1 = ∠ 3 = 33°

Answer:

g = 1.6t

Step-by-step explanation:

Here, we want to select the equation that shows the correct relationship between g and t

We are told that after 6 seconds, we have 9.6 gallons of water

So the amount per second will be 9.6/6 = 1.6 gallons per second

So the relationship between the two will be

g = 1.6t

Where t is the time and g is the gallons

Answer:

( y-b) / m    +a = x

Step-by-step explanation:

y−b=m(x−a)

Divide each side by m

(y−b)m=m/m(x−a)

( y-b)/m  = x-a

Add a to each side

( y-b) / m +a = x-a+a

( y-b) / m    +a = x

Answer:

y − b = m(x − a)

y − b = mx - ma

(y - b) / m = x - a

((y-b)/m) + a = x
