Upon formation of an equation from a given pattern, we know how the variables in the patter are related. Using the equation, we can find the value of one of the missing variables if the rest are known and also predict the values of the pattern at given conditions.
An example:
y = 2x + 5
if we are to predict the value of y at x = 3, we simply substitute 3 into x
y = 2(3) + 5
= 11
The correct answer is the first choice: (-3/2 , 9/2),
To find the new points, you have to perform both of the transformations listed. First is a dilation by 3/2. Then, a second dilation must be performed by 1/2.
This means you multiply the values by 3/2, then 1/2.
The points changes from (-2, 6) to (-3, 9) to (-3/2, 9/2).
Answer:
Step-by-step explanation:
i dont know sorry
Multiply out the brackets first.
So 2(-4y-9)-5y becomes -8y-18-5y [2 times -4y and 2 times -9]
Then simplify -8y-5y-18 to the answer ......-13y-18 or -(13y+18)
4+h+-8+-h
(h+-h)+(4+-8)
Answer is =-4
