The last one, as the the scale factor is 3. If we divide each side of the first triangle by their corresponding sides, such as (21/7, or 6/2), we get the same result, which is 3. All others are wrong because in the first one we are not giving all sides, and the second one doesn’t have the same scale factor for its sides. Hope this helps.
Answer:
There are 90 ways.
Step-by-step explanation:
We have ten people and we have to chose 2 of those people to be the president and vice president. So first we can chose a president, we have 10 choices for president as there are 10 people.
Now we can chose vice president but this time we only have 9 choices because we already chose a president which gives us 9 other people to chose who the vice president is.
Now we need to multiply 10 and 9 together which gives us the total amount of possible combinations for president and vice president if there are 10 people to chose from.
10*9 multiplying
= 90.
Therefore there are 90 ways for a president and a vice president to be chosen for a sorority from ten people.
Answer:
y = 4x - 3
Step-by-step explanation:
Find two point of the line
(0,-3) ; (1,1)
Use this formula
(y - y1)/(y2-y1) = (x-x1)/(x2-x1)
(y-(-3)/(1-(-3) = (x-0)/(1-0)
(y+3)/4 = x
y+3 = 4x
y = 4x -3
