So.. checking the picture below
we can say y = y, or just do a substitution and end up with
once you know, how long is "x", then you can simply use the cosine of 72° to get "r"
thus
If the equation is
that's true for all s, since 3/2+1=5/2
So all of them result in true statements
Answer: All of the above
Let's just do one for yuks, s=5.
(5/2) s = 25/2
(3/2)s + s = 15/2 + 5 = 15/2 + 10/2 = 25/2
That checks.
(x-4)^2=36
take square roots,
± (x-4) =6
=>
x-4=6 => x=10
-(x-4)=6 => x-4 = -6 => x=-2
Answer:
114 red marbles
Step-by-step explanation:
if there is one black marble per 19 red marbles, it is 1:19 ratio of black to red. Multiply your ratio by 6 and you get 6:114 black to red marbles.
Answer:
9/2
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -4 -5)/( 0 -2)
= -9/-2
= 9/2
