Find its x-coordinate.

Mathematics
1 answer:
Ilya [14]2 years ago
7 0

Answer:

2.5

Step-by-step explanation:

The formula to find the midpoint of a line segment: (\frac{1}{2}x_{1} + \frac{1}{2}x_{2}, \frac{1}{2}y_{1} + \frac{1}{2}y_{2})

<u><em>Where:</em></u>

x_{1} = -5\\x_{2} = 10\\y_{1} = 9\\y_{2} = 8

1) Substitute the values into the midpoint formula.

(\frac{1}{2}*-5 + \frac{1}{2}*10, \frac{1}{2}*9 + \frac{1}{2}*8)

2) Solve it.

= (-2.5 + 5, 4.5 + 4)

= (2.5, 8.5)

Jaymie wants to construct congruent angles with a compass and straightedge, while Annie wants to construct congruent segments wi
SashulF [63]

Jaymie will measure the segment and then place the point just across from the line's beginning point to create a congruent segment that shows the similarity between them.

<h3>What are the conditions of the congruent triangle?</h3>

Triangles that are equivalent in terms of size and form are known as a congruent triangle.

Segments will be built using the straightedge, and measurements will be taken using the compass. They will pick a starting point and draw a line using the straightedge, then use the compass to finish the job.

To make the congruent segment, Jaymie will measure the segment and then position the point that is opposite from the line's starting point.

Jaymie, on the other hand, will have to work a bit harder with the compass since she will need to draw a semi-circle in the original angle and transfer this measurement to the new line in order to create congruent angles.

Solve for x in the equation 2x^2-4x-9=29
Andrews [41]

Answer:

x = 1  ±2sqrt(5)

Step-by-step explanation:

2x^2-4x-9=29

Add 9 to each each side

2x^2-4x-9+9=29+9

2x^2-4x=38

Divide by 2

2/2x^2-4/2x=38/8

x^2 -2x =19

Complete the square

x^2 -2x + (-2/2)^2 = 19 +(-2/2)^2

x^2 -2x +1 = 19+1

(x-1)^1=2 = 20

Take the square root of each side

sqrt((x-1)^2) = ±sqrt(20)

x-1 =  ±sqrt(20)

Add 1 to each side

x-1+1 = 1  ±sqrt(20)

x = 1 ±sqrt(20)

Simplifying the square root of 20

x = 1  ±sqrt(4)sqrt(5)

x = 1  ±2sqrt(5)

Bas_tet [7]

Answer:

-1

Step-by-step explanation:

Slope formula: (y₂ - y₁) / (x₂ - x₁)

= (2 - 1) / (1 - 2)

= -1

PLEASE, I'M STUCK! Sketch the graphs of x = 7 and y=-1. Then find the point at which the two graphs intersect.
ycow [4]
Hello!

I have attached three graphs. The first one for x = 7, second one for y = -1, and third one with both x = 7 and y = -1 on the same graph. 

Hope this helps :))
