Someone help me out. I dont know how to do this

Fittoniya [83]

Answer:

$\huge\boxed{r_{x-axis}(x,\ y)\to(x,\ -y)}$

Step-by-step explanation:

Read the coordinates of the points:

A(-1, 0) → A'(-1, 0)

B(0, 2) → B'(0, -2)

C(3, 2) → C'(3, -2)

D(4, 0) → D'(4, 0)

(x, y) → (x, -y)

Check:

A → A': (-1, 0) → (-1, -0) = (-1, 0) CORRECT

B → B': (0, 2) → (0, -2) CORRECT

C → C': (3, 2) → (3, -2) CORRECT

D → D': (4, 0) → (4, -0) = (4, 0) CORRECT

What would a solution to the equation 100=(8+2x)(10+2x) mean in this situation

alexandr402 [8]

Step-by-step explanation:

100 = ( 8 + 2x) ( 10 + 2x )

100 = 80 + 36x + 4x ^2 ( binomial product )

80 + 36x + 4x^2 = 100

80 + 36x + 4×^2 - 100 = 100 - 100

4x^2 + 36x - 20 = 0

I am not able to write the next steps but you can use symbolab to find out the answer and for the clear understanding

Point B has coordinates (1,2). The x-coordinate of point A is negative 8. The distance between point A and point B is 15 uni

olchik [2.2K]

Answer:

The point A will be (-8,14) or (-8,-10).

Step-by-step explanation:

Point B has coordinates (1,2) and the x-coordinate of point A is - 8.

Let us assume that the coordinates of point A are (-8,k).

Now, given that the point A is 15 units apart from point B.

Therefore, from the distance formula, we can write that

$\sqrt{(1 - ( -8))^{2} + (2 - k)^{2}} = 15$

Now,squaring both sides, we get

$(1 - ( -8))^{2} + (2 - k)^{2} = 225$

⇒ $(2 - k)^{2} = 225 - 9^{2} = 144$

⇒ 2 - k = ± 12

⇒ k = 14 or -10.

Therefore, the point A will be (-8,14) or (-8,-10). (Answer)

We know that the distance between two points on the coordinate plane ( $x_{1}, y_{1}$ ) and ( $x_{2}, y_{2}$ ) is given by

$\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2}}$ .
