Answer:
-4/5
Step-by-step explanation:
use point slope form, which is y2-y1/x2-x1
plug in the numbers to get 10 -(-2)/-7-8. double negatives make a positive, so -2 turns into a positive. so adding them together makes 12/-15. simplify it to get -4/5.
Step-by-step explanation:
it's late but I hope it helps :)
imagine that the > symbol is just an equal sign
so for example
x+2>4
will look like
x+2=4
and you solve normally
×=2
now we bring the symbol back
x>2
but if you multiple or divide by a negative the sign flips
so say you have
-2x>4
make it into
-2x=4
solve
x=-2
but instead of >
you put
x < -2
Step-by-step explanation:
Number of areangements = 10C4
= 10 * 9 * 8 * 7 / (1 * 2 * 3 * 4) = 210.
Answer:
Let the number be x
According to Question ,
2x + 3x = 40
5x = 40
x = 8
therefore , the number is 8
