Answer:
x = -9
Step-by-step explanation:
6 - 2/9x = 8
Subtract 6 from each side
6-6 - 2/9x = 8-6
-2/9 x = 2
Multiply each side by -9/2 to isolate x
-9/2 * -2/9x = 2*-9/2
x = -9
Answer:
![3x^{2} +38x+80](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B38x%2B80)
Step-by-step explanation:
Hello!
A trinomial is a expression consisting of three different terms
To turn this into a trinomial we multiply everything to each other
<u> 3x </u>
3x * x = ![3x^{2}](https://tex.z-dn.net/?f=3x%5E%7B2%7D)
3x * 10 = 30x
<u> 8 </u>
8 * x = 8x
8 * 10 = 80
Now we put them all together in an equation
![3x^{2} +30x+8x+80](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B30x%2B8x%2B80)
Combine like terms
![3x^{2} +38x+80](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B38x%2B80)
The answer is ![3x^{2} +38x+80](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B38x%2B80)
Hope this helps!
Answer:
4/10 or 2/5
Step-by-step explanation:
probability of each letter:
J = 0/10
U = 2/10
M = 1/10
P = 1/10
The problem is: d=rt
you are solving for r
d=rt
-- --
t t
you divide both sides by r, so your answer is:
d/t=r or r=d/t
I hope this helped! :))

Explanation:
Factorizing your equation we get
cot
(
x
)
=
0
so
cos
(
x
)
=
0
we get the following Solutions in the given interval
x
=
π
72
or
x
=
3
π
2
for the second case we get
cot
(
x
)
=
−
1
so
cos
(
x
)
=
−
sin
(
x
)
and we get
x
=
3
π
4
or
x
=
7
π
4
Hint:
To get the Solutions of the last equation you can use
√
sin
(
x
+
π
4
)
=
0
