Answer:
x = 5.5
Step-by-step explanation:
so firstly you would takeaway 3 from both sides
then you would divide 11 by 2 which is 5.5
and that's your answer 5.5
14 = 3 + 2x
11 = 2x
x = 5.5
<span>Solve the following equation in the real number system. Please show all of your work.
example:
x³-6x²-10x+12=0
...
f(x)=x³-6x²-10x+12
A graphing calculator will show that there is one zero at x=-2
Divide f(x) by (x+2) by long division or synthetic division
(x³-6x²-10x+12)/(x+2)=x^2-8x+6
solve for other two zeros
x^2-8x+6=0
complete the square
(x^2-8x+16)+6-16=0
(x-4)^2=10
x-4=±√10
x=4±√10=7.16 and -.84
ans:
x=-2, -.84 and 7.16</span>
Answer: 83 over 20
Step-by-step explanation:
.15 = 15 over 100 = 3 over 20
1 = 20 over 20
The 4 = 80 over 20
80 over 20 + 3 over 20 = 83 over 20
