Answer:

Triangle ADB is congruent to triangle DBC

Step-by-step explanation:

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length.

Step-by-step explanation:

Answer:

yeah it should be 20 they're correct

#3, #19, and #16 please!!

Answers

To answer number 3 all you have to do is put 15 times x <_ 12 (put a line directly underneath the sign)

To answer number 19, do 21-11= 10 This means that X=10

X(10) plus 11=21

21=21

[10 + 11] >_ 21


To solve 16.

Add 3 to 13 to get 16

Then you’ll have [3x +4] >_ 16

Once you have this, subtract 4 from both sides.

Then you’ll have 3x>_ 12

Now you can divide each side by 3 to get x>_4. X=4

So if we plug that in [3x +4] >_ 13, you’ll get

[3(4) +4] >_ 13

And then you’ll get

[16] >_ 13

Solve 4x + 8y = 16 for x.

I got x = 4-2y

4x+8y=16
-8y=-8y

4x=16-8y

x=4-2y
C) X = -2y + 4

4x + 8y = 16

4x = 16 - 8y

4x = 4 (4 - 2y)

x = 4( 4 - 2y)/4

Sandy has 15 roses, 5 daisies, and 10 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?

Answers

Answer:

5

Step-by-step explanation:

Sandy has 15 roses, 5 daises and 10 tulips

She wants to arrange the flower in such a way that each bouquet will have the same flower in it

Therefore the greatest number of flowers that will be in each bouquet is 5 flowers this is so inorder to make each bouquet contain equal number of flowers, this means that one bouquet must not be greater than the other.

SOMEONE PLEASE ANSWER
the equation is 7x-3 over 9 > 8-2x

Answers

Answer:

solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]

The graph is attached below.

Option C is correct option.

Step-by-step explanation:

We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]

First we will solve the inequality to find value of x

Solving:

[tex]\frac{7x-3}{9}\geq 8-2x[/tex]

Step 1: Multiply both sides by 9

[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]

Step 2: Adding 3 on both sides

[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]

Step 3: Add 18x on both sides

[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]

Step 4: Divide both sides by 25

[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]

So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]

The graph is attached below.

Option C is correct option.

Identify the domain of the function.

Answers

Answer:

Step-by-step explanation:

domain represents the numbers at the x endpoints of a graph.

on the graph we see that on the left, the line ends when x is -4

on the right, the line ends when x is 4

the domain is

-4, 4

but notice how on the left there is an open circle

this will be written with a parentheses

( -4, 4

and notice how on the right there is a closed circle

this will be written with a bracket

(-4, 4]

so the answer is C

what is the coefficient of -2x+8=10 ​

Answers

Step-by-step explanation:

Let's solve your equation step-by-step.

−2x+8=10

Step 1: Subtract 8 from both sides.

−2x+8−8=10−8

−2x=2

Step 2: Divide both sides by -2.

−2x−2=2−2

x=−1

Answer:

Answer:

-2

Step-by-step explanation:

The coefficient of an equation or expression is any constant that precedes a variable. So, in this case, the only variable is x, so the coefficient is the preceding number, -2.

x = 20

Step-by-step explanation:

You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]

a = 12

b = 16

and c would be x.

12^2 + 16^2 = c^2

144 + 256 = c^2

The standard form of the given expression is 7x - y = 17

Equation of a line in standard form

The equation of line in standard form is expressed as Ax + By = C

Given the equation

y + 3 = 7(x - 2)

Expand

y + 3 = 7x - 14

y -7x = -14 - 3

-7x + y = - 17

7x - y = 17

Hence the standard form of the given expression is 7x - y = 17
