Which is the solution to the following equation?
4x^2-12x+9=5

Answers

Answer 1

Answer: we assume that
if xy=0
x and y=0

first make it equal to zero

minus 5 on both sides
4x^2-12x+4=0
undistribute 4 for ease
4(x^2-3x+1)=0
since 4 does not equal zero, and the only thing that will get it to zero is 0,
x^2-3x+1=0
use quadratic equation

if you hahve
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}$
1x^2-3x+1=0
a=1
b=-3
c=1

x= $\frac{-(-3)+/- \sqrt{(-3)^(2)-4(1)(1)} }{2(1)}$
x= $(3+/- √(9-4) )/(2)$
x= $(3+/- √(5) )/(2)$
x= $(3+ √(5) )/(2)$ or $(3- √(5) )/(2)$

aprox
x=2.61803 or 0.381966

Hello,
In a Venn 's diagram: A={Custumer edu},B={french}, U=the class.

#(A\B)=22-2=20
#(B\A)=20-2=18
#(A∩B)=2
#U=80

p=(20+2+18)/80=20/40=1/2

Answer C (11/40+1/4-1/10=20/40=1/2)

Which function represents the number of seconds, s, in d days? (Hint: The number seconds in a day is 24 × 60 × 60 = 86,400.). The function that represents the number of seconds, s, in d days is f(d) =

Answers

You simply multiply the days with the number of seconds in a day.
f(d) = 86400d.
I hope that this is the answer that you were looking for and it has helped you.

Answer: f(d) = 86,400d

Trying to write an equation for line on graph without any numbers given to plug into for slope

Answers

In that situation, you use the information you DO have. It's not always
enough to do the job. But often it is, and in that case, you use what you
do have to answer the question or solve the problem.

Sadly, I can't be any more specific than that. You haven't told us what
information you do have ... only what information you don't have.

Final answer:

The equation for the line is y = 3x + 9.

Explanation:

The equation for a line can be written in the form y = mx + b, where m represents the slope and b represents the y-intercept. In this case, since the slope is 3 and the y-intercept is 9, the equation for the line is y = 3x + 9.
