Answer:

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:

The number of given points=3, y, and z

Step-by-step explanation:

Answer:

B $0.75

Step-by-step explanation:

0.75x 3= 2.25

if the hotdogs are 2x as much as the drinks then

0.75x2= 1.50

then if there are 2 hot dogs

1.50x2=3

2.25+3=5.25

Answer with step-by-step explanation:

x = 10

Step 1: Simplify both sides of the equation.

x - 6 + 2 = 6

x + (-6) + 2 = 6

(x) + (-6 + 2) = 6

x + (-4) = 6

x - 4 = 6

Step 2: Add 4 to both sides.

x - 4 + 4 = 6 + 4

x = 10

Answer:

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

C ≤ 22

Step-by-step explanation:

How many triangles can be constructed with side lengths of 6.4 cm, 8.3 cm, and 14.6 cm? 0 1 more than one

Answer:

47.1 ft

Step-by-step explanation:

To find the circumference of a circle, use the formula c = πd

We know that π = 3.14 and d = 15 ft so we can substitute this into the formula:

c = 3.14 × 15 = 47.1 ft

Answer:

I believe the answer would be 2/3

Step-by-step explanation:

Because if it's a 6 sided dice, and you need a number greater than 2 then there are 4 other numbers. This gives you 4/6. Simplify it and it gives you 2/3./ Hope this helps! :)

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

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:

d

Step-by-step explanation:

Substitute x = -1 into the equations. If the solution is y = 4 for both, then (-1, 4) is the solution.

(a) y = 1 + 3 = 4

    y = -1 + 1 = 0

(b) -1 - y = 2  ⇒  y = -3

  -1 + y = -6  ⇒  y = -5

(c) -1 + y = -2  ⇒  y = -1

7(-1) - 4y = 8  ⇒  y = -15/4

(d) y = 1 + 3 = 4

   y = 2(-1) = 6 = 4

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.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

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°.

Step-by-step explanation:

Cost = 3 rupees per sq. m.

Answer:

-104 is the answer .....

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)

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