-10x-6y=0 -4x -6y=54 find the solution of this system of equations

Mathematics
1 answer:
ad-work [718]2 years ago
7 0

You can see that the term -6y appears in both equations. In this cases, we can leverage this peculiarity and subtract the two equations to get rid of the repeated term. So, if we subtract the first equation from the second, we have

(-4x -6y) - (-10x-6y) = 54-0 \iff 6x = 54 \iff x = 9

Now that we know the value of x, we can substitute in any of the equation to deduce the value of y: if we use the first equation, for example, we have

-10x-6y=0 \iff -10\cdot 9 - 6y = 0 \iff -90-6y=0 \iff 6y = -90 \iff y = -15

Given f (x) = 3x - 5 find f (x - 2)
antiseptic1488 [7]

Answer:

3x-11

Step-by-step explanation:

f (x) = 3x - 5

f(x-2)

Replace x in the function with x-2

f (x-2) = 3(x-2) - 5

           =3x-6 -5

           =3x-11

If x &gt; 0 and y &gt; 0, where is the<br> point (x, y) located?
Scrat [10]
  • Given, x > 0, y > 0.
  • So, the values of x and y are less than 0, that means, they are negative integers.
  • If we divide a Cartesian plane with the x-axis and y-axis, we get four quadrants.
  • 1st Quadrant : (+,+)
  • 2nd Quadrant : (-,+)
  • 3rd Quadrant : (-,-)
  • 4th Quadrant : (+,-)
  • Since the values of x and y are both negative, so (x, y) is located in the <em><u>3rd Quadrant</u></em>.

Hope you could get an idea from here.
