Answer:

x = 1, y = 6

Step-by-step explanation:

y = 6x

2x + 3y = 20

Plug y as 6x in the second equation and solve for x.

2x + 3(6x) = 20

2x + 18x = 20

20x = 20

$\frac{20x}{20}= \frac{20}{20}$

x = 1

Plug x as 1 in the first equation and solve for y.

y = 6(1)

y = 6

Answer:

y=6 , x=1

Step-by-step explanation:

y=6x

2x+3y=20

Substitute 6x into y because y=6x.

2x+3(6x)=20

2x+18x=20

20x=20

Then subsitiute 1 into the first equation in x value

y=6(1)

(02.02 MC) Triangle ABC is shown. A is at negative 2, 1. B is at negative 1, 4. C is at negative 4, 5. If triangle ABC is reflec

Bezzdna [24]

Given:

The vertices of a triangle ABC are A(-2,1), B(-1,4) and C(-4,5).

Triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees.

To find:

The point B'.

Solution:

If a figure reflected over x-axis, then

$(x,y)\to (x,-y)$

$B(-1,4)\to B_1(-1,-4)$

If a figure reflected over y-axis, then

$(x,y)\to (-x,y)$

$B_1(-1,-4)\to B_2(-(-1),-4)$

$B_1(-1,-4)\to B_2(1,-4)$

If a figure rotated 180 degrees about the origin, then

$(x,y)\to (-x,-y)$

$B_2(1,-4)\to B'(-(1),-(-4))$

$B_2(1,-4)\to B'(-1,4)$

So, the coordinate of point B' are (-1,4).

Therefore, the correct option is A.
