This scale drawing shows an enlargement in a figure.What is the value of x? Enter your answer as a decimal in the box.

1 answer:

8 0

Let’s find the scale factor (the number each number on the left has been multiplied by)
14/10 = 1.4
The scale factor is 1.4 so 10 has been multiplied by 1.4 to get 14

so you are now going to do 1.4 * 4 = 5.6

5.6 is your answer!!

emmainna [20.7K]

ANSWER

T(-2,1)

EXPLANATION

Let T(a,b) be the coordinates.

When this point is rotated 90° counterclockwise about the origin,

Then,

$T(a,b)\to \: T'( - b,a)$

If this point is then translated using the rule;

$(x,y)\to (x-1,y+7)$

then,

$T(a,b)\to \: T'( - b,a) \to T"( - b - 1,a + 7)$

It was given that, T"(-2,5)

This implies that,

-b-1=-2

-b=-2+1

-b=-1

b=1

a+7=5

a=5-7

a=-2

Therefore the coordinates of T are:

(-2,1)
