Answer:

[tex]{y,x}={2,-10/3}[/tex] ( No)

Step-by-step equation:

System of Linear Equations entered :

 [1]           y=-4+6

 [2]           3x+4y=-2

Equations Simplified or Rearranged :

  [1]    y = 2

  [2]    4y + 3x = -2

Graphic Representation of the Equations :

   0? + y = 2        3? + 4y = -2  

Solve by Substitution :

// Solve equation [1] for the variable  y

  [1]    y = 2

// Plug this in for variable  y  in equation [2]

  [2]    4•(2) + 3x = -2

  [2]    3x = -10

// Solve equation [2] for the variable  x

  [2]    3x = - 10

  [2]    x = - 10/3

// By now we know this much :

   y = 2

   x = -10/3

We are done

Solution :

{y,x} = {2,-10/3}

Answer:

m=-3/2

Step-by-step explanation:

To find slope we can use the formula y2-y1/x2-x1

Let's plug in our points

-1-2/1--1 which is -3/2

Our slope is -3/2

Answer:

m=-3/2

Step-by-step explanation:

In order to solve this problem, you must use the slope formula.

Slope formula:

[tex]\sf{\dfrac{Y_2-Y_1}{X_2-X_1}=\dfrac{RISE}{RUN} }[/tex]

y2=(-1)

y1=2

x2=1

x1=(-1)

Rewrite the problem down.

Solve.

[tex]\sf{\dfrac{-1-2}{1-(-1)}=\dfrac{-1-2}{1+1}=\dfrac{-3}{2}=\boxed{\sf{-\dfrac{3}{2} }} }[/tex]

Therefore, the slope is -3/2, which is our answer.

Step-by-step explanation:

Answer:

Question 3: 2.7 hours

Question 4: 2.3 hours

Step-by-step explanation:

Question 3:

Time taken by 1st delivery driver = t1 = 6 hours

Time taken by 2nd delivery driver = t2= 5 hours

Time together = T

[tex]{\dfrac{ 1 }{ T } = \dfrac{ 1 }{ t1 } + \dfrac{ 1 }{ t2 }}[/tex]

[tex]{\dfrac{ 1 }{ T } = \dfrac{ 1 }{ 6 } + \dfrac{ 1 }{ 5 }}[/tex]

[tex]{\dfrac{ 1 }{ T } = 0.166+0.2 = 0.366}[/tex]

[tex]{T = \dfrac{ 1 }{ 0.366 } = 2.732}[/tex]

Rounded to the nearest tenth: 2.7 hours

Question 4:

The first valve takes 4 hours to completely drain = t1

[tex]\mathrm{Rate\:for\:first\:valve\:will\:be\:\dfrac{1}{4}\:per\:hour}[/tex]

The second valve taken 5.25 hours to completely drain = t2

[tex]\mathrm{Rate\:for\:second\:valve\:will\:be\:\dfrac{1}{5.25}\:per\:hour}[/tex]

Combined time = T

[tex]{\dfrac{ 1 }{ T } = \dfrac{ 1 }{ t1 } + \dfrac{ 1 }{ t2 }}[/tex]

[tex]{\dfrac{ 1 }{ T } = \dfrac{ 1 }{ 4 } + \dfrac{ 1 }{ 5.25 }}[/tex]

[tex]{\dfrac{ 1 }{ T } = 0.25+0.190 = 0.44}[/tex]

[tex]{T = \dfrac{ 1 }{ 0.44 } = 2.272}[/tex]

Rounded to the nearest tenth: 2.3 hours

The inequalities that can represent this situation if m is the number of songs Miguel can buy are:

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, it is provided that:

If he buys m = 0, he doesn't need to open an account, thus, saving all money of gift.

Else, if he buys m > 0, then:

Let c = total cost he will have to pay for m songs.

m songs will cost [tex]1.50 \times m[/tex] dollars

Total cost he will have to pay = account activation charge + m songs; cost

[tex]c = 1 + 1.5m[/tex]

(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)

Since we have limited money, so:

c needs to be less than or equal to $25

This is symbolically written as:

[tex]c \leq 25[/tex]

But since we've got [tex]c = 1 + 1.5m[/tex], thus:

[tex]1 + 1.5m \leq25\\[/tex] (option A).

This can be reversed as:

[tex]25 \geq 1 + 1.5m[/tex] (Option E)

(both things are same, as [tex]c \leq 25[/tex] or [tex]25 \geq c[/tex] both are same since if c is less than or equal to 25, then that means 25 is greater than or equal to c)

(the case when c= 0, we have 0 < 25, so it is also included in those two options, as a special case)

Answer:

A and E are correct

Step-by-step explanation:

The time required for the invested money to reach the accrued amount is 8 years.

The compound interest formula is expressed as;

A = P(1 + r/n)^(n*t)

Where A is accrued amount, P is principal, r is rate,  and t is time.

Given that;

Plug the given values into the compound interest formula and solve for time t.

A = P(1 + r/n)^(n*t)

t = In(A/P) / n[ In( 1 + r/n ) ]

t = (In( $8900 / 6500 )) / ( 365[ In( 1 + 0.04/365 ) ] )

t = (In( $8900 / 6500 )) / ( 365[ In( 1 + 0.04/365 ) ] )

t = 7.857

t = 8 years.

Therefore, the required time is 8 years.

Answer: the coefficient is 5

From the AAS property of congruency the side ab≅ac in the isosceles triangle.

Congruency generally shows the similarities between two triangles or any other shape for the similarity of the two shapes they should have any three properties same like their three sides, Three angles or one angle two sides and so on.

Now for an Isosceles triangle abc given in the figure

[tex]\angle bad=\angle cad[/tex]

[tex]\angle abd=\angle acd[/tex]

[tex]ad=ad[/tex]   (common side)

So from the AAS property, the triangle [tex]\Delta bad=\Delta acd[/tex] are congruence

12 crew members

Step-by-step explanation:

to find out this question you should first make 66 2/3% into a fraction

that is 99.99...% percent which is also 2/3

you can then divide 8 men by 2/3

that is 8/1 divided by 2/3 which is essentially 8/1 * 3/2

that turns into 12

that means there are 12 crew members

Option B. ∠3 = 130°

Step-by-step explanation:

In the given question a, b, c are the parallel wires and pipe cleaner is the transverse.

Now we take two parallel wires a, c and pipe cleaner as transverse then

we have to find the relation between angle 4 and 130°

∠4 = ∠9 [ alternate interior angles ]

∠3 = 130° [ they are the alternate interior angles ]

Therefore option B. is the correct option.

Answer:

B. They are alternate interior angles, so angle 3 also measures 130°.

The maximum number of chairs he can buy is C ≤ 22

Step-by-step explanation:

Let B represent the number of beds the hotel manager can buy.

Let C represent the number of chairs the hotel manager can buy.

Putting this into an expression, we have:

150B + 50C ≤ 2000

Since the hotel manager buys 6 beds, putting this into the information above:

150 (6) + 50C ≤ 2000

900 + 50C ≤ 2000

50C ≤ 2000 - 900

50C ≤ 1100

The solution is x = -4

Step-by-step explanation:

y=4x+2
we can see here that y equals 4x+2

y =3x-2

The y here is the same y, therefore we ban subtitute the first equation into the second one, like this:

y =3x-2

4x+2 = 3x-2

now just solve it algebraically.

4x + 2 - 3x = 3x -2 -3x

x +2 -2 = -2 -2

x = -4

The solution is x = -4

Answer:

any numbers that are multiples of 10, such as

10 and 20

40 and 60

50 and 80

Step-by-step explanation:

Because 5 is a factor of 10, all multiples of 10 will also be multiplies of 5, such as 10, 20, 30, 40, 50, 60, and so on.

we have to calculate the values ​​of A and B, so we have to:

[tex]A=100\\B=5[/tex]

Since the equation is:

[tex]R(X)=(500+ax)(50-bx)[/tex]

And the following information was given:

A school typically sells 500 yearbooks each year for $50 each.

The economics class discovers that they can sell 100 more yearbooks for every $5 decrease in price.

So knowing that by increasing 100 more books sold this is equal to A and the decrease in value is going to be equal to b.
