Answer:k=10
Step-by-step explanation:
Answer:
Solution given:
-2x²+7x-6=0
2x²-7x+6=0
Comparing above equation with ax²+bx+c
we get
a=2
b=-7
c=6
By using Vieta's theorem
X1+X2=
=
again
X1X2=
=
=3
Answer:
remember to round numbers to 1 significant figure
Step-by-step explanation:
usually in an exam when you're asked to estimate the answer to a calculation, usually you round each number to 1 sf and then work on from there.
The answer to this question is 23
First thing you need to do is distributive property and that will give you
7-56-7x=-14+4x then combine like terms which will then give you
-49-7x=-14+4x Next get your letters on the left do that by subtracting 4x which will give you -49-11x=-14. After that you will add 49 to both sides which will give you
-11x= 35. Divide by -11 to get x=3.18
