If it is the decimals that are giving you trouble, you can multiply both sides by 10, giving you 16k=32
To find k you divide both sides by 16
(16k)/16=(32)/16
The 16's cancel out, and the 32/16 becomes 2.
Final answer:
K=2
Answer:
The quantity of negative 1 plus or minus square root 33 all over 3
Step-by-step explanation:
3x2+6x=8
3x^2+6x-8=0
Quadratic formula
x=-b +or-√b^2-4ac/2a
a=3
b=6
c=-8
x=-b +or-√b^2-4ac/2a
=-6 +or- √(6)^2 - 4*3*-8/2*3
=-6 +or- √36-(-96)/6
=-6 +or-√36+96/132
=-6 +or- √132/6
=-6 +or- 2√33/6
=-6/6 +or- 2√33/6
= -1 +or- √33/3
The quantity of negative 1 plus or minus square root 33 all over 3
Answer:
-8+14x
Step-by-step explanation:
By distribution, -2(4-7x) = -8+14x
Let's convert the word descriptions into mathematical equations first for illustration.
f(x) = x^2 - x - 12
g(x) = -2.5x - 2
Then, we equate g(x) and f(x). The final equation becomes
x^2 - x - 12 = -2.5x - 2
Then, we simplify by transposing and combining like terms.
x^2 - x + 2.5x -12 + 2 = 0
x^2 + 1.5x - 10 = 0
Since this is a quadratic equation, we find the roots by using the quadratic formula
where a = 1, b = 1.5 and c=-10
Thus, the answer is x = 2.5, -4.
