Equation 1: -6x = 26 - 20y
Equation 2: -8x = 8-20y
Step 1: Cancel out the Ys
-6x = 26 - 20y --> -6x = 26 - 20y
(-8x = 8-20y) x -1 --> + 8x = -8 + 20y
------------------------
2x = 18
x = 9
Step 2: Plug in X and solve for Y (P.S. you can plus X into either of the equations)
-6(9) = 26 -20y
-54 = 56 - 20y
-80 = -20y
y = 4
Step 3: Check the answer:
-6(9) = 26 - 20(4)
-54 = -54
Therefore:
x = 9 y = 4
-5r + (-3) = 51
Add 3 to both sides:
-5r = 54
Divide both sides by -5 to get r alone:
r = -10.8
To check this, plug in -10.8 into the equation: -5(-10.8) + (-3) = 51
54 + (-3) = 51
54 - 3 = 51
51 = 51
This statement is true, so the answer is correct.
They simplify operations when the systems are not encumbered by the variables.
Answer:
Step-by-step explanation:
a + b = 331 (million)
b = 25 (million)
a + 25 = 331
a = 331 - 25
a = 306 (million).......singer a took in 306 million
Answer:
For a rational function, set the denominator equal to zero. Whatever value of x that makes the denominator equal to zero corresponds to the vertical asymptote.
