Answer:

5

Step-by-step explanation:

We need to isolate the variable, aka make y on one side. So, if we divide 8 on both sides, it will be

y8=40

y8/8=40/8

y=5

​If \left| OA\right| =5∣OA∣=5 and \left| OA'\right| =7.5∣OA ′ ∣=7.5, what is the scale factor, rr, of this dilation?
Igoryamba

Answer:

The scale factor is 1.5

Step-by-step explanation:

Given

\left| OA\right| =5

\left| OA'\right| =7.5

Required

Determine the scale factor

The scale factor (k) is calculated using:

k = \frac{\left| OA'\right|}{\left| OA\right|}

Substitute values for OA and OA'

k = \frac{7.5}{5}

k = 1.5

<em>The scale factor is 1.5</em>

Helpppppppppppppppppppp pleaseeeeeeeeeee
Umnica [9.8K]

Answer:

FG = 16

Step-by-step explanation:

if df bisects <edg then  triangles DFE and DFG are similar AAA

since DF is the same in both triangles triangles DFE and DFG are congruent

therefore FE = FG

n+5 = 2n-6

subtract n from each side

n-n+5 = 2n-6-n

5 = n-6

add 6 to each side

5+6 = n

n=11

FG  = 2n-6

      =2*11 -6

    = 22-6

   = 16
