3x^2 - 6 = 2x wat is discriminant of the quadratic equation
Answer:
The discriminant is 76
Step-by-step explanation:
The equation needs to be in the form
ax^2 +bx +c =0
3x^2 - 6 = 2x
Subtract 2x from each side
3x^2 -2x - 6 = 0
The discriminant is
b^2 - 4ac
a = 3 b = -2 c = -6
(-2)^2 -4(3) (-6)
4 + 72

f(x)=2x
which expression represents f^-1(x)?
Answer:
hey !
your answer is C
x=
x/2
Step-by-step explanation:
If the function f(x)=2x then the inverse function is f⁻¹(x) =x/2.
What is a function?A relation is a function if it has only One y-value for each x-value.
The given function is f(x)=2x.
y=2x
Interchange the variables.
x=2y
Now solve for y
y=x/2
Replace y with f⁻¹(x) to show the final answer.
f⁻¹(x) =x/2
Hence, if the function f(x)=2x then the inverse function is f⁻¹(x) =x/2.

can someone please help fast will give brainelist
Answer:
A.
Step-by-step explanation:
y = mx + c
m = y - y¹ / x - x¹
= 4-3 / 4-2
= 1/2
using (4,4)
4 = 1/2 × 4 + c
4 = 2 + c
c = 2

Solve the system by substitution. If the system is inconsistent or has dependent equations, say so.
-X-5y = -6
y = 6x-5
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
• A. The system has a single solution. The solution set is O. (Type an ordered pair.)
B. There are infinitely many solutions and the equations are dependent. The solution set is {(x,y)} (Type an ordered pair.)
C. The system is inconsistent. The solution set is the empty set
Answer:
The (single) solution is (1, 1).
Step-by-step explanation:
The second equation tells us that y = 6x-5. Substitute this 6x - 5 into the first equation, as follows: -x - 5(6x - 5) = -6
Then -x - 30x + 25 = -6. Combining like terms, we get -31x = -31, so that x = 1. Subbing this result into the second equation, we find y: y = 6(1) - 5 = 1. The solution is (1, 1).

In the diagram below of circle O, chords ab and cd intersect at E.
If measure of arc AC = 72° and measure of arc AEC = 58°, how many degrees are in measure of arc DB?
Answer:
Correct option: 3
Step-by-step explanation:
When we have a crossing of two chords in a circle, there is a property that relates the angles in the intersection point and the arcs defined in the circle. From this property, we have that:
mAEC = (1/2) * (mAC + mBD)
Using the values of mAEC = 58° and mAC = 72°, we have that:
58 = (1/2) * (72 + mBD)
116 = 72 + mBD
mBD = 116 - 72
mBD = 44°
Correct option: 3

Answer:
X=14.4
Step-by-step explanation:
The equation for this problem is (a)(x)=b^2. So substituting the equation,
(10)(x)=(12)^2. Isolating x, we get x=14.4. to check our answer we solve the equation. (10)(14.4)=(12)^2 --> 144=12^2 --> 144=144. The statement is true.
