Hey there!
To find the discriminant of an equation, you first need to identify the A, B, and C of your equation. You can do this by comparing your equation to the standard form.
Standard Form: ax² + bx + c
Equation: 3x² – 10x + 2
If you add 2 to both sides, you can get everything on one side and you can assure that all of your numbers are accurate.
A will be equal to 3, B will be –10, and C will be 2.
Now, you need to plug in those numbers into the discriminant equation:
b² – 4ac
If your discriminant is 0, there is one rational solution. If it's a positive perfect square, there are 2 rational solutions. If it's a positive non–perfect square, there will be 2 irrational solutions, and if it's a negative number, there will be 2 complex solutions.
Hope this helped you out! :-)
Answer:
70° , 70°
Step-by-step explanation:
The 2 angles are corresponding and are congruent, then
23x + 1 = 4 + 22x ( subtract 22x from both sides )
x + 1 = 4 ( subtract 1 from both sides )
x = 3
Then the angles are
23x + 1 = 23(3) + 1 = 69 + 1 = 70°
4 + 22x = 4 + 22(3) = 4 + 66 = 70°
16 - 12 = 4 flowers
4f = 6 days
1 flower = 1.5 days
1.5 × 16 = 24 days
Hope this helped!!
Answer:
B. g(x)
Step-by-step explanation:
g(x) is a function of odd degree, so its minimum value is -∞, which is far less than the minimum value of -2 that f(x) has.
_____
Any even-degree term (with a positive coefficient) will have a minimum value of zero, hence the minimum value of f(x) is the constant added to the 4th degree term.
Answer:
angle Q = 66
Step-by-step explanation:
nvm ik how to do it
First find the value of u
2u + 6 + 3u + 24 = 180 degrees
combine like terms
5u + 30 = 180 degrees
subtract 30 from each side
5u = 150
divide each side by 5
u = 30
plug it in
2(30) + 6
60 + 6 = 66
angle Q = 66
