Mumz [18]

Answer:

(-6,-4)

Step-by-step explanation:

So there actually is really easy way to solve this problem(that many people will never teach you for some weird reason).

Find difference between two points first in x and y direction.

X difference = (-3 - (-8)) = 5

Y difference = (-1 - (-6))  = 5

Multiply 2/5 to each difference

X difference 5 * 2/5 = 2

y difference 5* 2/5 = 2

just add the two number to First point(point A)

-8 + 2 = -6

-6 + 2 = -4

(-6,-4)

This person did something wrong and I do not know what it is :( Please help this is for points!
Arlecino [84]

Answer:

0.4 cm

Step-by-step explanation:

The magnifying glass basically zooms into smaller objects. If the insect appears to be 2cm, then it is actually smaller than this. It cannot be 10 cm.

If the scale factor is 5, then this means that the insect is zoomed in 5 times through the magnifying glass. Use the following ratio:

\frac{2}{5}

This fraction can also be seen as division, so:

2÷5=0.4

The insect is actually 0.4 cm long.

(or 4 millimeters)
