Answer:
Option A
Step-by-step explanation:
We are given that
Scale factor=2
Center of dilation=(0,0)
Point A(0,2) and point B (2,0).
Slope of line f=
Substitute the values
Slope of line f=
Distance between A and Origin (0,0) is given by
Using distance formula
OB=
Length of OA'=2OA=2(2)=4 units
Length of OB'=2(OB)=2(2)=4 units
x-intercept of line f' at x=4
y-intercept of line f' at y=4
Therefore, the points A' and B' are given by
(0,4) and (4,0)
Slope of line f'=
Slope of line f and f' are equal.Therefore, lines f and f' are parallel.
Option A is true.
Answer:
Linear relationship
Step-by-step explanation:
This is a linear relationship as it is expressed in the form y= mx+b
Here y= n b = -6 and x= m
A linear equation corresponds to a straight line hence it shows a linear relationship.
There is a correspondence between algebra and geometry through co ordinate system. We can convert a point into a pair of numbers and vice versa.
If we are given the value of y we can determine x and vice versa.
n = 4m – 6
In the given equation suppose x = 5 so y will be 14
n= 4(5)- 6
n= 20-6= 14
Also if we have y= 18 x will be 6
n = 4m – 6
18 + 6= 4m
24/4= m
m= 6
The answer would be D.
Randall should choose the rebate offer because the shoes will be $2.40 less than if he chooses the sale price.
88 - 20% = 70.4
88 - 20 = 68
70.4 - 68 = 2.4 (2.40)

Answer: 14cm
Step-by-step explanation:
The diameter of a circle is twice the radius.
Therefore, the diameter = 2*7 cm = 14cm
