You would multiply everything by 2. A dilation of 2 is an enlargement, or an increase in shape. If it was -2, it would be a reduction.
Multiply everything by 2:
(-2,3) = (-4,6) (3,4)= (6,8) (4,-1)= (8,-2)
I hope this helps you!

1. Divide the first term of the numerator by the first term of the denominator, and put that in the answer.
2. Multiply the denominator by that answer, put that below the numerator.
3. Subtract to create a new polynomial.
Answer:
1. yes
2. yes
3. no
4. no
Step-by-step explanation:
Replace x by each value of x.
1. yes
2. yes
3. no
4. no (this is not a solution because the value must be greater than 44 not equal to)
The description expresses three points which can be used for a standard form equation. The vertex is stated to be (0,0) and is a maximum; two other points are (-21,-74) and (21,-74)
The equation for vertex form of a parabola:
y=a(x-h)^2+k
vertex (h,k)
thus our equation will be:
y=a(x-0)^2+0
thus
y=ax^2
using one of the points, the value of a will be:
-74=a(21)^2
a=-74/441
thus the equation will be:
y=-74/441x²
Answer:
20 miles away
Step-by-step explanation:
40*2 = 80
30*2=60
80-60=20
