Step-by-step explanation:

The picture of the question in the attached figure

we know that

A translation and a reflection are rigid transformations, that produce congruent figures'

Remember that

Two figures are congruent if their corresponding sides and their corresponding angles are congruent

In this problem

Triangle JKL and Triangle J'K'L' are congruent

so

JL=J'L'

substitute the given values

8=2x-4

solve for x

Pam and Erin are both planting gardens for their backyards. They want their gardens to be proportional. If pams garden has a len
Simora [160]

Step-by-step explanation:

Pam and Erin want the gardens to be proportional.

<em>proprtional</em><em>-</em><em> </em><em>equal</em><em> </em>

Pams garden has a length of 16 and width of 12. To find the area of Pam's garden multiply the length by the width.

<em>16</em><em>×</em><em>12</em><em>=</em><em> </em><em>192</em><em> </em>

Now that we know the area of Pam's garden, we can set up and equation for Erin's garden. Since they have to be equal we know that Erin's garden should equal 192. Thus we solve for the length by dividing the width from the total.

<em>192</em><em>÷</em><em>21</em><em>=</em><em>9.14</em>

Find the equation using the y=mx+c method
lesya [120]

Answer:

<h2>y=2x+0 (y=2x)</h2>

Step-by-step explanation:

so we know that y=mx+c

c is the point where the line crosses the y-axis

y=mx+0

m is the gradient

the gradient is rise/run

pick any two points

so it is 2/1

2/1 is 2

therefore it is

y=2x+0
