Answer:
x=3y/x-4x
Step-by-step explanation:
3x+8=x+6y
2x+8=6y
2x=6y-8
x=3y/x-4x
Answer:
The value of k for the expression to be undefined is 9 .
Step-by-step explanation:
Given as :
The rational expression is written in the form

Now, according to question
The expression to be undefined , denominator should be 0
<u>As,
is infinite ( ∞ ) term and it is undefined , so for expression to be undefined , the denominator should be 0</u>
∴ k² - 18 k + 81 = 0
Or, k² - 9 k - 9 k + 81 = 0
Or, k ( k - 9 ) - 9 ( k - 9) = 0
Or, ( k - 9 ) ( k - 9 ) = 0
Or, ( k - 9 ) = 0 , ( k - 9 ) = 0
∴ k = 9
So, The value of k = 9
Hence The value of k for the expression to be undefined is 9 . Answer
Answer:
that's not quadratic formula or square method
Step-by-step explanation:
i personally thing the quadratic formula is easier which is
x = -b+-√b^2 -4ac
----------------------------
2a
you just plug in a b and c into the equation which is
x^2 is a which is 1
-6x is b which is -6
1 is c and its just 1
the answer also needs to involve a radical which for example 3√2
Dilation- A figure that grows or shrinks but still maintains its very shape.
Answer:
answer is c
Step-by-step explanation:y =
−0.3x
The given equations are in slope-intercept form, y = mx + b, where b represents the y-intercept.
Proportional relationships must pass through the origin. Therefore, the y-intercept for the equation must be 0. The y-intercept for y = −0.3x is 0.
