To determine the point at which medians of a triangle intersect one another, it is necessary to determine the equations of the lines for two

medians. The coordinates of which two points are used in the calculation of the equation for a given median?


A. the perpendicular bisector of one side and its intersection with a second side

B. the midpoint of one side of a triangle and the midpoint of a second side

C. one vertex of a triangle ahd the point of intersection of the angle bisector and the opposite side

D. one vertex of a triangle and the midpoint of its opposite side

Answer:

1. the quality of being made up of exactly similar parts facing each other or around an axis.

2. For something to be an odd function, it has to have symmetry to the origin, not the x-axis. This means that if it has a point like (a, b), it also has the point (-a, -b). For example, y = x is an odd function because it does this.

21+3=24 24+3=27 27+3=30

Step-by-step explanation:

joe can only use 3gb of data . bill is 21

21+9+30

1gb=3

3*9=9

3(3)+21=30

3×3=$9

Answer:

y = 130,000(1.03)ˣ

Step-by-step explanation:

The general form of an exponetial function is y = abˣ, where a is the initial value (when x = 0), and b is the multiplier (the growth or decay factor). Here, we start with a population of 130,000, so our initial value a = 130,000. A growth of 3% each year represents a growth factor of 1.03, so after x years, the population y should be y = 130,000(1.03)ˣ.

The exponential function in terms of x and y is y = 130,000(1.03)ˣ

The exponential function is a mathematical function denoted by

y = abˣ

where a is the initial value (when x = 0)

and b is the multiplier (the growth or decay factor).

population starts from 130,000, so

Initial value a = 130,000.

A growth of 3% each year represents a growth factor of 1.03,

so after x years, the population y should be

y = 130,000(1.03)ˣ

Therefore , The exponential function in terms of x and y is y = 130,000(1.03)ˣ

Answer:

D

Step-by-step explanation:

Each factor on the right has to be multiplied by the equation on the left and then you add them.

The expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.

To rewrite the expression (3x² + 4x - 7) ( x- 2) using the distributive property, we need to distribute each term in the first polynomial to each term in the alternate polynomial.

(3x² + 4x - 7) ( x- 2)

= 3x²( x- 2) + 4x( x- 2)- 7( x- 2)

Now, distribute each term

= 3x³- 6x²+ 4x²- 8x- 7x + 14

Combine like terms

= 3x³- 2x²- 15x + 14

Thus, using the distributive property, the expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.

I'll help you with this so reflections is not hard.

For reflect over x-axis you need to switch the sign on Y. formula for points like this is (x,y). An example is reflect (2,4) over the x-axis. you just change the sign of y making the answer (2,-4).

For reflect over y-axis you change the sign of X.For example reflect over the y-axis (3,7) all you have to do is change the sign of X which leaves you with the answer of (-3,7).

sign is basically + or - if need to know.

Hi there! I'm here to help. :)

Okay, so here you are solving for x. To solve for x, you must get it alone on one side of the equal sign. As we can see, it is not alone, and it is with 1 1/4 on the left side of the equal sign.

To get it alone, we need to subtract 1 1/4 from both sides. However, to subtract fractions, we need to make sure they have the same denominator. Looking at the fractions, we can see that they have two different denominators.

Begin by converting both fractions into improper fractions:

1 1/4 = 5/4

3 1/2 = 7/2

So now our equation looks like this: x + 5/4 = 7/2

Now we need to make it to where we our fractions have the same denominator.

Our current denominators are 4 and 2. The LCM (lowest common multiple) of 4 and 2 is 4, so you leave 5/4 as it is (because it's denominator is already 4) and you change 7/2.

Multiply 2 * 2 to make the denominator 4 in 7/2, but whatever you do to the denominator, you MUST do to the numerator. So multiply 7 * 2 = 14. Now your fraction looks like this: 14/4

Now we have:

1 1/4 = 5/4

3 1/2 = 14/4

Our denominators are the same now! Now here comes the easy part: We subtract! Do 3 1/2 - 1 1/4, or, 14/4 - 5/4. To subtract fractions, simply subtract the numerators and leave the denominators as is. 14 - 5 = 9, so 14/4 - 5/4 = 9/4.

Now our equation looks like this:

x = 9/4

LASTLY: All of your options are mixed numbers, so convert this improper fraction back into a mixed number. 9/4 = 2 1/4.

So, x = 2 1/4. :)
