Answer:
90
Step-by-step explanation:
10!/(10-2)!
n!=n(n-1)!
10•9•8!/(10-2)!
10•9•8!/8!
The 8! cancels out and you're left with 10•9
So, your answer is 90
Answer:
x = 10.9
Step-by-step explanation:
Since the triangle is right, use the tangent ratio to find the value of x
tan36° = 
= 
= 
Multiply both sides by 15
15 × tan36° = x
⇒ x = 10.9 ( to nearest tenth )
No, because (2,0) is a coordinate. x=2 and y=0. So just plug in the numbers where there's x or y with the appropriate number, (2 or 0). So in the first equation, x-2y=0, when you pug in the numbers, 2-2(0)=0, you know it's wrong because 2-0=0 isn't correct. So no. the point (2,0) is not a solution to the first equation. Now plug in the numbers for the second coordinate. You get 2(2)-3(0)=1. So 4-0=1. This is once again false no no. (2,0) satisfies neither equations.
Answer:
please what is the question
Answer: B.no
Step-by-step explanation:
To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer
