The line with equation y= 2x + 3 is reflected in the x-axis.

Mathematics
1 answer:
nadya68 [22]3 years ago
3 0

Step-by-step explanation:

When a graph is reflected about the x-axis, their x-intercept(s) are invariant point(s).

For y = 2x + 3, the x-intercept is -3/2.

Also the slope of the line graph when reflected about the x-axis will change from m to -m.

Therefore the new slope is -2.

We have y = -2x + c.

When x = -3/2, y = 0.

=> (0) = -2(-3/2) + c, c = -3.

Hence the answer is y = -2x - 3. (E)

Anna11 [10]

Responder:

2 1/4 m; 225 cm

Explicación paso a paso:

Dado:

Cortar 9 metros en 4 partes de la misma longitud;

Por lo tanto,

9 metros / 4

= 2,25 metros

Por lo tanto, cada varilla será 2.25 = 2 1/4 m

En cm;

1 m = 100 cm

2,25 metros = x

x = 100 * 2,25

x = 225 cm

Select the correct answer. Shape 1 and shape 2 are plotted on a coordinate plane. Which statement about the shapes is true? A. S
IceJOKER [234]

Answer:

Since I cant say which answer due to no graph, I'll tell you How to do so.

Step-by-step explanation:

if it is A, then the there is at least one angle or line length that is not the same. To find the area of a grided shape, use the traingle theorm of a^2+b^2=c^2.

if it is B, that meants moving the shape to the other will result in a perfect fit. Be sure to find if all side lengths are the same as that means that the shape IS congrouent, as equal side length means equal angles. However, it will not be this choice if the shape is mirrored to the other

A rotation and tranlastion means it is flipped either upside down or up and moved to the shape.

D, a reflection, which means its the opposite. Like a mirrored shape. Then you move it.

faust18 [17]

Answer: I’m pretty sure it’s 4.50%

Step-by-step explanation:

Well when you divide the number (1.045) by 100 you get 4.5 and so 4.5 of 1500 would give you the balance.

devlian [24]
<span>Let the height of tree be denoted as AB and the shadow cast by the tree be BE. ABE is the triangle formed the tree, rays and the ground. Let the height of the person be CD and the length of his shadow be DE. CDE is the triangle formed by the person, rays and the ground. We have two triangles. Both the person and the tree stand vertically over the horizontal ground, therefore they make 90 degrees with the ground. The angle formed at the ground is the same for the both the triangles. Therefore, by AA similarity the two triangles are similar. We know that if two triangles are similar, then their sides are proportional. Therefore, AB/CD =BE/DE AB/6 = 143/11 AB= (143/11) *6 AB = 78 ft.</span>
