Graph triangle RST with vertices R(3, 7), S(-5, -2), and T(3, -5) and its image after a reflection over x = -3.​
kirill115 [55]

Given:

The vertices of a triangle are R(3, 7), S(-5, -2), and T(3, -5).

To find:

The vertices of the triangle after a reflection over x = -3 and plot the triangle and its image on the graph.

Solution:

If a figure reflected across the line x=a, then

(x,y)\to (-(x-a)+a,y)

(x,y)\to (-x+a+a,y)

(x,y)\to (2a-x,y)

The triangle after a reflection over x = -3. So, the rule of reflection is

(x,y)\to (2(-3)-x,y)

(x,y)\to (-6-x,y)

The vertices of triangle after reflection are

R(3,7)\to R'(-6-3,7)

R(3,7)\to R'(-9,7)

Similarly,

S(-5,-2)\to S'(-6-(-5),-2)

S(-5,-2)\to S'(-6+5,-2)

S(-5,-2)\to S'(-1,-2)

And,

T(3,-5)\to T'(-6-3,-5)

T(3,-5)\to T'(-9,-5)

Therefore, the vertices of triangle after reflection over x=-3 are R'(-9,7), S'(-1,-2) and T'(-3,-5).

The length of the tunnel is 460miles. If 1 inch represents 60 miles what is the length of the tunnel?
kotegsom [21]

Answer:

The length of the tunnel is 7.66667 inch

Step-by-step explanation:

We are given

1 inch =60 miles

now, we can find for 1 mile

so,

60 miles = 1 inch

we get

1mile=\frac{1}{60}inch

we are given

total length is 460 miles

so, we can multiply both sides by 460

460\times 1mile=460\times\frac{1}{60}inch

now, we can simplify it

460miles=7.66667inch

So,

The length of the tunnel is 7.66667 inch
