Is it equal to the measure if angle C

In an isosceles triangle, the measure of the vertex angle (Angle B in this case) is equal to the measure of the other base angle. This is because in an isosceles triangle, the angles opposite the equal sides are also equal.

In an isosceles triangle ABC, Angle B, the angle between the two sides of equal length, is known as the vertex angle. The two base angles of an isosceles triangle are always equal. Therefore the measure of Angle B will be equal to the measure of Angle C. This property comes from the fundamental characteristics of an isosceles triangle, where two sides are of equal length and the angles opposite these equal sides are also equal.

Answer:

f(-3) = -5/2

f(-1) = 3/2

f(3) = 3/4

Step-by-step explanation:

To find the values, we just have to replace by the values given (-3, -1, 3).  Since there are different definitions of the function depending on the range of x, we just have to pick the right one before replacing x by its value.

x = -3

When x ≤ -1, the function is 7/2 + 2x

So, x = -3 is certainly  ≤ -1, so....

f(-3) = 7/2 + 2 (-3) = 7/2 - 6 = 7/2 - 12/2 = -5/2

x = -1

When x ≤ -1, the function is 7/2 + 2x

So, we do the same calculation:

f(-1) = 7/2 + 2 (-1) = 7/2 - 2 = 7/2 - 4/2 = 3/2

x = 3

When x ≥ 3, the function is defined as: (1/4)x or x/4.  So,

f(3) = 3/4

The output values of f(-3), f(-1), and f(3) in the piece-wise function are -5/2,  3/2, and 3/4 respectively.  

To determine the output value of f(-3), f(-1), and f(3) in the piece-wise function, we simply plug in the values of x in the piece that is within the domain.

To solve for f(-3), plug x = -3 into the piece with the domain of x ≤ -1:

f( x ) = 7/2 + 2x

Pug in x = -3:

f( -3 ) = 7/2 + 2(-3)

f( -3 ) = -5/2

To solve for f(-1), plug x = -1 into the piece with the domain of x ≤ -1:

f( x ) = 7/2 + 2x

Pug in x = -1:

f( -3 ) = 7/2 + 2(-1)

f( -3 ) = 7/2 - 2

f( -3 ) = 3/2

To solve for f(3), plug x = 3 into the piece with the domain of x ≥ 3:

f( x ) = (1/4)x

Pug in x = 3:

f( 3 ) = (1/4) × 3

f( 3 ) = 3/4

Therefore, the values for f(-3), f(-1), and f(3) are -5/2,  3/2, and 3/4 respectively.  

c = 2x + 3. The third side of the triangle is 2x + 3.

The key to solve this problem is using the perimeter of a triangle equation which is P = a + b + c, where a, b, and c are the sides of the triangle.

We know that the perimeter P = 3x² + 7x, let's suppose a = 6x - 7, b = 3x² - x + 4, and c is the unknow.

Clearing c from the equation:

c = P - (a + b)

c = 3x² + 7x - (6x - 7 + 3x² - x + 4)

c = 3x² + 7x - 6x + 7 - 3x² +x - 4

Grouping the equal terms:

c = 3x² - 3x² + 7x + x - 6x + 7 - 4

c = 0 + 8x - 6x + 3

c = 2x + 3

Answer:

x = classic

x + 2342 = contemporary

3500 = x + (x +2342)

3500= 2x + 2342

and then you would just solve the equation, but it does not ask for a solution

Step-by-step explanation:

x = classic

x + 2342 = contemporary

3500 = x + (x +2342)

3500= 2x + 2342

Answer: Jared has a total of 3500 dvds of two types, contemporarys and classics.

we also know that Jared has 2342 more contemporary dvds than classics.

Now, how we write this as system of equations?

if x is the number of classics, and y the number of contemporarys, then:

1) x + y = 3500

and

2) y - x = 2342

this is the system of equations, but just for fun we can solve it!

in the second equation we can leave y alone in the right side ande get: y = 2342 + x, and then replace it in the first equation.

x + y = 3500

x + (2342 + x) = 3500

2*x = 3500 - 2342 =1158

x = 1158/2 = 579

So Jared has 579 classic titles.

then:

y + x =3500

y + 579 = 3500

y = 3500 - 579 = 2921

And Jared has 2921 contemporary titles.

I think 5x represents 90 degrees.

5x = 90

x = 18

ANSWER

[tex]x = 18 \degree[/tex]

EXPLANATION

A semicircle subtends an angle of 90° at the circumference.

From the diagram, the semicircle subtends an angle of (5x)° at the circumference.

We equate this angle to 90° and solve for x.

This implies that,

[tex]5x = 90 \degree[/tex]

Answer:

(2,-1)

Step-by-step explanation:

The solution of the system of equations 2x + 3y = 1 and 5x + 2y = 8 is x = 2 and y = -1.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation.

And simultaneous equation is the system of equation.

Given:

System of equations,

2x + 3y = 1,  {equation 1}

And 5x + 2y = 8.    {equation 2}

To find the solution:

Multiply 5 to the equation 1 and multiply 2 to the equation 2.

And then subtract the equation 2 to the equation 1.

We get,

11y = -11

y = -1

And 2x = 4

x = 2

Therefore, the solution is x = 2 and y = -1.

The answer is:

The first option,

[tex]y=-\frac{1}{2}x-3;x<-2[/tex]

To answer the question, we need to look for an inequality that fits with the following description:

- Negative slope, since the segment "a" is decreasing.

- x- axis interception at x equal to -6

- One of its point is located at (-2,-2)

- The segment exists from -∞ to -2.

So, checking we have:

Firs option

[tex]y=-\frac{1}{2}x-3[/tex]

With,

[tex]x<-2[/tex]

- Finding the y-axis component when x is equal to -2, we have:

[tex]y=-\frac{1}{2}*(-2)-3\\y=1-3=-2[/tex]

We have that one of the points of the segments is located at (-2,-2)

- Finding the "x" intercept, we have:

[tex]0=-\frac{1}{2}x-3\\\\\frac{1}{2}x=-3\\\\x=2*-3=-6[/tex]

Also, (from the inequality and the graph) we know that, the given segment exists from the negative infinite numbers to -2.

[tex]x-axis_{interception}=-6[/tex]

Answer:

True

Step-by-step explanation:

The numbers 20, 21, and 29  are a Pythagorean triplet and can be the dimensions of a right triangle.

In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.

A triangle with sides of lengths 20, 21, and 29 is a right triangle.

Three numbers can be the sides of a triangle if the sum of two of them is greater than the third. So, since

20+21 > 29,

20+29 > 21, and

21+29 > 20

Are trivially true, they can be the sides of a triangle.

The given numbers are a Pythagorean triplet and can be the dimensions of a right triangle.

20,21 and 29 is a Pythagorean triplet, since

[tex]20^2+21^2=29^2[/tex]

So you also know that they form a right triangle.

Hence, the numbers 20, 21, and 29  are a Pythagorean triplet and can be the dimensions of a right triangle.

The formula for a quadratic equation is y = ax^2 + bx + c. In this case, a = -4, b = 8, and c = 12. The direction of the parabola can be determined by a. If a is positive, the parabola opens upwards, and if a is negative, the parabola will open downwards.

Answer:

x = (8.75 - 2 5/6) / 7.1 + (4 1/2 + 2 2/3) / 4 3/10

x = 2.5

Answer:

2  1/2

Step-by-step explanation:

Order of operations rules require that we do any work within parentheses first.  Thus, calculate (8.75 - 2  5/6); it is (5  11/12).  Next, calculate (4  1/2 + 2  2/3); it is ( 7  1/6).  So what we have now looks like:

(5  11/12) / 7.1  + (7  1/6) / (43/10)    (Note that 4  3/10 = 43/10)

Performing the two indicated divisions, we get:

5/6 + 1  2/3.

Since the LCD here is 6, we add:    5/6 + 1  4/6, which comes out to

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

a linear function is

y = ax + b

so, for the first pair of x, y

8.5 = 2a + b

b = 8.5 - 2a

the second pair

15.25 = 5a + b

let's use the substitution information from the first pair :

15.25 = 5a + 8.5 - 2a

6.75 = 3a

a = 2.25

b = 8.5 - 2×2.25 = 8.5 - 4.5 = 4

so, we get as linear function

y = 2.25x + 4

that means the y-intercept (x = 0) is at y = 4

y = 2.25×0 + 4 = 4

The y-intercept of this function will be at (0, 4).

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

In the table below, x represents miles traveled and y represents the cost to travel by train.

Miles (x)    Cost (y)

   2            8.50

   5           15.25

   8          22.00

  12          31.00

Then the linear equation will be

y - 8.50 = [(31.00 - 8.50) / (12 - 2)] (x - 2)

y - 8.50 = 2.25(x - 2)

y - 8.50 = 2.25x - 4.5

          y = 2.25 + 4

The graph of the equation is given below.

Then the y-intercept of this function will be at (0, 4).
