The coordinates of A in the pre-image is (-1,2).
D0, 3(x,y) means (x,y) → (3x,3y)
A'(-3,6)
B'(-0.5, 8)
C'(2,6)
D'(1,3)
E'(-2,3)
The coordinates of the pre-image are multiplied by 3 resulting to the coordinates of the given image. So, we simply divide each value of x and y by 3 to get the coordinates of the pre-image.
A'(-3,6) → -3/3 = -1 ; 6/3 = 2 → A(-1,2)
Answer:
2
Step-by-step explanation:
Write out all the factors for 14
Then write out the multiples of 7
Compare the numbers then find the greatest number in 14's factors that isn't in 7's multiples
First :<span>Graph the solution set of the inequality
and interpret it in the context of the problem. For example: As a
salesperson, you are paid $50 per week plus $3 per sale. This week you
want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions.
second:</span>
<span> Simplify using the inverse of addition or subtraction. Simplify further by using the inverse of multiplication or division.
then find what you want to use!
