If the diameter of a circle has 4 units, what is its circumference?

For the given function f(x) = –5|x + 1| + 3 the value of x = 2, -4

To find the answer to this question, we will have to find the values of x where:

-5|x + 1| + 3 = -12

We can solve this equation for x to find the values of x that satisfy this equation.

-5|x + 1| + 3 = -12

Subtract 3 from both sides.

-5|x + 1| = -15

Divide both sides by -5.

|x + 1| = 3

Now here, the equation will split off into two different equations. These two are:

x + 1 = 3

x + 1 = -3

Lets solve the first one first.

x + 1 = 3

Subtract 1 from both sides.

x = 2

Now we solve the second one.

x + 1 = -3

Subtract 1 from both sides.

x = -4

So now we have the answers x = 2 and x = -4.

So the values of x are x = 2, -4

Answer:

  154°

Step-by-step explanation:

Angles formed from opposite rays and sharing a vertex are called "vertical angles." Vertical angles are congruent.

Angle 2 and the one marked 154° are vertical angles, so they have the same measure.

Angle 2 is 154°.

Step-by-step explanation:

Reflection in x-axis: (x, y) ----> (x, -y).   (x value stays the same)

Reflection in y-axis: (x, y) ----> (-x, y).   ( y value stays the same)

There's a lot going on in this problem, but I think I know how to solve it. So let's first address the fact that opposite angles are equal.

Let's also address the fact that (x + 6) + (3x - 4) add up to equal 90. So with that information, we can write a problem.

x + 6 + 3x - 4 = 90

Add the x's.

4x + 6 - 4 = 90

Combine the 6 and 4.

4x + 2 = 90

Subtract the two on both sides.

4x = 88

Finally, divide by 4.

x = 22

But by no means are we done yet. We still have to find out the entire angle MFE's measure, so we'll substitute 22, our new x value, into the equation for MFE - (x + 6)

22 + 6 is the new equation.

22 + 6 = 28

Angle MFE is 28°. I took the liberty of solving for the other angle, too, so I could check the answer. And as of my checking, this answer is correct because

62 + 28 = 90

I hope this answers your question.

By geometric and algebraic properties the angles BTC, TBC and TBC from the triangle BTC are 128°, 26° and 26°, respectively.

According to the figure, the triangle BTC is inscribed in the circle by two points (B, C). In this question we must make use of concepts of diameter and triangles to determine all missing angles.

Since AT and BT represent the radii of the circle, then the triangle ABT is an isosceles triangle. By geometry we know that the sum of internal angles of a triangle equals 180°. Hence, the measure of the angles A and B is 64°.

The angles ATB and BTC are supplmentary and therefore the measure of the latter is 128°. The triangle BTC is also an isosceles triangle and the measure of angles TBC and TCB is 26°.

By geometric and algebraic properties the angles BTC, TBC and TBC from the triangle BTC are 128°, 26° and 26°, respectively.

•129n-131n=0

Combine 129n and -131n to get 2n
