X=y+4 and y=x+4

timofeeve [1]

Alright, for the two equations you gave me, which are x=y+4 and y=x+4, we can try substitution to get the answer! Substitution is when you take one variable from one equation and plug it into another equation to find out what both variables are!

To do this, we start with the first equation, x=y+4. Then, from the second equation we know that y=x+4 so we can plug x+4 in for the y in the first equation. We now have x=(x+4)+4 as our first equation.

Now, we can simplify! The parenthesis aren't important in this equation, so we can just get rid of them, giving us x=x+4+4. Now we can simplify to give us x=x+8. Now, all that's left is to subtract the x from both sides of the equation! This gives us 0=8, but we know that that's not possible because there is no way that 0 can equal 8. This means that this equation doesn't have an answer!

To check this, you can repeat the steps above with the second equation, but you will still end up with 0=8, and that, again, means that this equation doesn't have an answer.

Multiply and simplify. (12 2/3)(3 1/4) A) 36 1/12 B) 36 1/6 C) 41 1/12 D) 41 1/6

Tanya [424]

Answer:

41 1/6 is the answer lets do it step by step

Step-by-step explanation:

You are usually taught to multiply the improper fractions and simplify the result.

.. (38/3)*(13/4) = (38/4)*(13/3)

.. = (19/2)*(13/3)

.. = (19*13)/6

.. = 247/6

.. = 41 1/6

You can also multiply the parts.

.. (12 2/3)*(3 1/4) = 12*3 + 12*(1/4) +(2/3)*3 +(2/3)*(1/4)

.. = 36 +3 +2 +1/6

.. = 41 1/6

hope this helps:D

Please help!!

Mamont248 [21]

Answer:

(Q.1) No solution

(Q.2) True

(Q.3) x = 4 - 2y

(Q.4) True

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

Step-by-step explanation:

(Q.1) As shown in the first attached figure.

By graphing. x + 2y = 8 & x + 2y = -4

The two lines are parallel, there is no intersection points between the lines.

So, there is no solution to the system of equations.

Also, we should note the parallel lines have the same slope

to find it make the equation similar to y = mx + c where m is the slope

at this situation m = -1/2

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

(Q.2) As shown in the second attached figure.

By graphing the system of inequalities y> -3x+2 & y<2x+1

The Shaded area represents the solution of the system of inequalities

And the point (4,2) is inside the shaded area

So, The ordered pair (4,2) is a solution to the system of inequalities.

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

(Q.3)  solving the system { x+2y=4 & 2x+2y=6 } by substitution

From the first equation x + 2y = 4

we will find x in terms of y then plug it into the second equation

So, x + 2y = 4 ⇒ x = 4 - 2y

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

(Q.4) As shown in the third attached figure.

By graphing. 2x + 4y = 8 & x + 2y = 6

The two lines are parallel, there is no intersection points between the lines.

So, there is no solution to the system of equations.

Also, we should note the parallel lines have the same slope

to find it make the equation similar to y = mx + c where m is the slope

at this situation m = -1/2

HELP???? PLEASE AND FAST IM ON THE BRINK OF DEATH --

aleksandrvk [35]

Answer:

See below.

Step-by-step explanation:

Create a system of equations to represent this scenario.

Lin: 12 - 1/3x = y
Diego: 20 - 2/3x = y

1) A graph of these equations is attached below. Lin is in red; Diego is in blue.

2) The time (seconds) is on the x-axis, while the milkshake (oz) is on the y-axis. The graph shows the rate of change that the volume of the milkshake is decreasing for both Lin and Diego. The intersection point tells us at what time t (s) Lin and Diego have the same amount of milkshake left.

There is only one solution to this system of equations: (24, 4). This tells us that at t = 24 s, Lin and Diego both have 4 oz of milkshake left.

The zeros, aka where the graph touches the x-axis, tell us at what time Lin and Diego finish their milkshakes.

Lin finishes her milkshake later than Diego, at t = 36 s (36, 0), while Diego finishes his milkshake at t = 30 s (30, 0).
