If measure of arc AC = 72° and measure of arc AEC = 58°, how many degrees are in measure of arc DB?

Answers

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

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

Answers

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).

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.

3x−4y=−24 Response : A. y=34x+6 B. y=−6x−34 C. y=6x−34 D. y=−34x+6

Answers

Answer:

y = 3/4 x +6

Step-by-step explanation:

3x−4y=−24

Solve for y

Subtract 3x from each side

3x-3x−4y=-3x−24

-4y = -3x-24

Divide each side by -4

-4y/-4 = -3x/-4 -24/-4

y = 3/4 x +6

f(x)=2x
which expression represents f^-1(x)?

Answers

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.
