Answer:
490
Step-by-step explanation:
Let us first count the handshakes between two gremlins. There are 20 gremlins, so there must be 20*19/2=190 handshakes between two gremlins, making sure to divide by two to avoid over-counting.
There are 15 imps that shake hands with each of the 20 gremlins, which makes 15* 20 = 300 handshakes between imps and gremlins.
Adding these up, you have $300 + 190 = 490 total handshakes.
Hope this helps!
Answer:
y = -2/3x-9
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -2/3x+b
We have a point we can substitute into the line
-5 = -2/3(-6)+b
Subtract 4 from each side
-5-4 =4+b-4
-9 =b
y = -2/3x-9
Answer:
Her mistake was to change the inequality sign from ≥ to ≤.
The sign only changes when you multiply or divide both sides of an inequality by a negative number.
