First you have to isolate one of the equations for y=mx+b.
Then substitute the equation is made into the first equation
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!
Brainliest answer is always appreciated!<span />
If you take the square root of integers 1-100, the only rational numbers will be the perfect squares, hence the square root. Count how many squares there are between 1 and 100, inclusive, and subtract that number from 100 to get the number of rational and irrational numbers.
Answer:
Step-by-step explanation:
Yes 8-3=-4+9. 8-3=5. -4+9=5
