The center is (0,0)
You are looking for a scale factor of 4..
Point a is found at (-3,1)
Point B (4,-3)
Point C (2,3)
Point D (-1,4)
Multiply each value by the scale factor of 4..
x:
Point A = -3 * 4 = -12
Point B = 4*4=16
Point C= 2*4=8
Point D=-1*4=-4
y:
Point A= 1*4=4
Point B= -3*4=-12
Point C= 3*4=12
Point D= 4*4=16
Your dilated points are:
A : (-12,4)
B : (16,-12)
C : (8,12)
D : (-4,16)
Hope this helps!
If the ratio of the width to the length is 1 : 2 then, we can represent their respective lengths using x and 2x.
Width = x
Length = 2x
2(x) + 2(2x) = 324
2x + 4x = 324
6x = 324
x = 54
2x = 108
The width is 54 ft. and the length is 108 feet. Hope this helps!
1.50 of 2.50 expressed as a percentage is 60%
Answer: B
Explanation:
Given, f(x) = 3 • 2x
So , f(-2)=> x= -2
f(-2)= 3 • 2(-2)
f(-2)= 3 •(-4)
f(-2)= -12
