X=2y-6;y=3x-7substitution to solve systems of equations​

Mathematics
1 answer:
Debora [2.8K]3 years ago
4 0
<h2>Answer:</h2>

As you said, we can solve this system for y by using <em><u>substitution</u></em>.

x = 2y - 6\\y = 3x - 7\\\\y = 3(2y - 6) - 7\\\\y = 6y - 18 - 7\\\\y = 6y - 25\\\\-5y = -25\\\\y = 5

Now, using what we got for y, we plug it into one of the original equations to solve for x.

x = 2(5) - 6\\\\x = 10 - 6\\\\x = 4

Now we have the solution of this system.

(4, 5)

Answer:

Answer C is the only one in function notation.

Step-by-step explanation:

To find something in function notation, we look for 2 different criteria.

  • On the left side, it must say f( ), with a variable in the parenthesis.
  • On the right side, the variable being used must match that from the left side.

Since C is the only one that satisfies both of those needs, we know it is the answer.

Answer:

The corresponding point for the function  f(x - 4) is (4 , 1)

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- If the function f(x) translated horizontally to the right by h units, then

 the new function g(x) = f(x - h)  

- If the function f(x) translated horizontally to the left by h units, then

 the new function g(x) = f(x + h)  

- The given function is f(x)

- Point (0 , 1) lies on the graph of f(x)

- We need to find the corresponding point of (0 , 1) for the function

 f(x - 4)

- The function f(x - 4) means that f(x) is translated 4 units to the right

∵ x subtract by 4

∴ f(x) translated horizontally four units to the right

- If any point (x , y) translated 4 units to the right, then x-coordinate

 of the point will added by 4 to give image (x + 4 , y)

∵ The point is (0 , 1)

∴ Its image is (0 + 4 , 1)

∴ Its image is (4 , 1)

* The corresponding point for the function  f(x-4) is (4 , 1)

I travelled at 60km/h and took 2 hours for a certain journey. How long would it have taken me if I had travelled at 50km/h?​
Marina86 [1]

Answer:

2 hours and 24 minutes

Step-by-step explanation:

2 hours at 60 km/h means you have travelled 2*60=120 km

120 km at 50 km/h takes 120/50 = 2.4 hours

2.4 hours is 2 hours and 0.4*60 = 24 minutes.

Help! Will give branliest!!

Hello from MrBillDoesMath!

Answer:

sin(A) =   k/c

sin(C) =   k/a

Discussion:

By definition of sine ,

sin(A) = side opposite angle / hypotenuse  =  k/c

sin(C) = side opposite angle/ hypotenuse =  k/a

Added remark:

From the first equation, k = c sin(A). From the second equation k = asin(C). Hence.

asin(C) = csin(A)                => divide both sides by "ac"

sin(C)/ c = sin(A)/a          

Which is the law of sines for a triangle.

Thank you,

MrB
