Answer:

Step-by-step explanation:
A dilation is an enlargement or reduction of an object by a scale factor and with a center of dilation. The scale factor refers to the change in size. The center of dilation is a point about which we are dilating an object.
The dilation with the center of dilation at the origin and a scale factor of k has the rule

This means that the image of the point with coordinates (x,y) after the dilation by a scale factor of k with center of dilation at origin will have coordinates (kx,ky).
Answer:
The range is 40.
Step-by-step explanation:
Range is just the largest number minus the smallest.
70 - 30 = 40
Answer:
Therefore, ( 1 , 1 ) is the Solution to the Given Equations
Step-by-step explanation:
Given:
..............Equation ( 1 )
..............Equation ( 2 )
To Find:
x = ?
y = ?
Solution:
..............Equation ( 1 )
..............Equation ( 2 )
Substituting equation 1 in equation 2 we get

Substituting 'x' in Equation ( 1 ) we get

Therefore, ( 1 , 1 ) is the Solution to the Given Equations
The format for a standard form is ax+by=c.
So, we need to get rid of fractions in the equation first.
To do this, multiply both sides by the "LCM" of the fraction denominators..
The LCM of 4 and 2 is 4. So, multiply both sides by 4:
4y = 3x - 10
Now, change it to standard form by subtracting 3x from both sides:
-3x + 4y = -10
This doesn't match any of the choices. Am I wrong or is the choices wrong? idk
