For the positive answer i got x=2
Answer:
Both F and Z have symmetry.
Hi there!
Okay, so I was a bit confused by your question, but I tried to make it a bit easier and work out.
There was two ways I did this because I didn't want to NOT answer your question!
What about this:
3.2/15 cannot be simplified lower than what it is. Decimal form is 0.2133333 (repeating). I answered this part because I didn't know what 3. was (I at first thought it was part of the numerator. But now that I look at it again it may have been a question number. But just in case, I answered it like this anyway.)
Next!
I solved 2/15, which also cannot be simplified down lower than what it is. It's decimal form is 0.133333 (another repeating decimal.)
And so as you can see I answered two problems for you. If these are incorrect, let me know!
Hope this helps!
Answer:
(26/9 , -7/9)
Step-by-step explanation:
Here,
let the points be
X(-1,7) = (x1, y1)
Y(4,-3) = (x2,y2)
and let the ratio be...
m:n = 7:2
and.. let the point that divides the line be
P(x,y)
now using the section formula for internal division..
P(x,y) = ( m.x2 + nx.1 / m+ n , my2+ny2/m+n )
= ( 7.4+2.-1 / 7+2 , 7.-3 + 2.7/7+2 )
= ( 26/9 , -7/9 )
Answer:
x = 4
y = 8
Step-by-step explanation:
this is a 30-60-90 triangle and the sides have a constant ratio
the side across from the 30°∡ is 1
the side across from the 60°∡ is √3
the side across from the 90°∡ is 2
In this problem we can find 'x' by setting up this proportion:
x/12 = /1
cross-multiply:
x = 12
x = 12/
since we don't like to leave radicals in the denominator, we can multiply both numerator and denominator by to get:
12 ÷ · (· = , which equals 3)
so we have 12/3, which is 4
The 'y' value will be twice the 30° side, so 8
