Answer:
Step-by-step explanation:
Use the formula for calculate the distance between two points:
Calculate the distance AB. Substitute the coordinates into the formula. Then:
Calculate the distance A'B'. Substitute the coordinates into the formula. Then:
As you can see, the distance A'B' is the distance AB multiplied by 1/2. Therefore, this is the scale factor.
Answer:
2
Step-by-step explanation:
greatest common factor means the greatest number we can divide by for each of the number and still get a whole number
14 and 22. they are both even so one factor is 2
if we check, 14 & 22 aren't both divisible by 3,4,5,6,7,8,9,10,11,12,13,14 so the gcf is 2
Answer:
-25
Step-by-step explanation:
2a² - 5a + 4, for f(-3)
2(-3)² -5(-3)+4
2*(-27)+15+4
-54+19
= -25
Answer:
2x+y -3 =0
Step-by-step explanation:
0 = Ax + By + C is the general form of a line
2x+4y +2 = 3y +5
Subtract 3y from each side
2x+4y-3y +2 =3y+5-2y
2x+y +2 = 5
Subtract 5 from each side
2x+y +2-5 = 5-5
2x+y -3 =0
