hello :
<span>help :
<span>the discriminat of each quadratic equation :
ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x =
(-b±√Δ)/2a</span>
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions</span>
M to the power 4 squared minus 23
-16F temperature change divided by 4 hour difference from 8 to 12/noon.
-16 divided by 4 = -4
The answer is -4 degrees Fahrenheit.
The answer is the number that 'Y' must be in order for
the equation to be true.
That number is called the 'solution' to the equation.
Here's one way to go about finding it:
You said that - 6y - 3 = 3 - 6y
Add 6y to each side: - 3 = 3
Let's stop right here.
Is there any value of 'Y' that can make -3 = 3 ?
I don't think so.
Your equation has NO SOLUTION.
There is NO NUMBER that you can write in place of 'y'
in your equation
- 6y - 3 = 3 - 6y
and have it work out to be true.
That's OK. There are lots of equations that have no solution.
Answer:
The answer is $4.10
Step-by-step explanation:
If 3 pounds = $1.23
1 pound =1.23/3
= 0.41
Therfore 10 pounds = 10× 0.41 = $4.10
