Answer:
<h2>y-7=(x-5)</h2>
Step-by-step explanation:
<h3>to understand the solving steps</h3><h3>you need to know about</h3>
- linear equation i.g point-slope
- PEMDAS
<h3>given:</h3>
- m=1
- (x1,y1)=(5,7)
<h3>let's solve:</h3>
point-slope form is y-y1=m(x-x1)
so the point-slope equation is
<h3>y-7=1(x-5)</h3><h2>=y-7=(x-5)</h2>
Answer: B
Step-by-step explanation:
The ratio of the areas of similar figures is the square of the scale factor.
- Scale factor = image/preimage = 48/12 = 4.
So, the ratio of the areas is 16, and thus the area of DEF is (16)(90)=1440
