Answer:
x = -11
Step-by-step explanation:
Convert fraction into negative exponential form: ![(36^-^1)^x^-^4=(216^-^1)^x^+^1\\](https://tex.z-dn.net/?f=%2836%5E-%5E1%29%5Ex%5E-%5E4%3D%28216%5E-%5E1%29%5Ex%5E%2B%5E1%5C%5C)
Simplify using exponent power rule: ![(a^n)^m=a^n^m:36^-^x^+^4=216^-^x^-^1](https://tex.z-dn.net/?f=%28a%5En%29%5Em%3Da%5En%5Em%3A36%5E-%5Ex%5E%2B%5E4%3D216%5E-%5Ex%5E-%5E1)
Convert both sides of the equation into terms with same base:![(6^2)^-^x^+^4=(6^3)^-^x^-^1](https://tex.z-dn.net/?f=%286%5E2%29%5E-%5Ex%5E%2B%5E4%3D%286%5E3%29%5E-%5Ex%5E-%5E1)
Simplify using exponent power rule:
![(a^n)^m=a^n^m:6^-^2^x^+^8=6^-^3^x^-^3](https://tex.z-dn.net/?f=%28a%5En%29%5Em%3Da%5En%5Em%3A6%5E-%5E2%5Ex%5E%2B%5E8%3D6%5E-%5E3%5Ex%5E-%5E3)
Based on the given conditions, corresponding exponents are equal:
![-2x=8=-3x-3](https://tex.z-dn.net/?f=-2x%3D8%3D-3x-3)
Rearrange unknown terms to the left side of the equation:
![-2x+3x=-3-8](https://tex.z-dn.net/?f=-2x%2B3x%3D-3-8)
Combine like terms: ![x=-3-8](https://tex.z-dn.net/?f=x%3D-3-8)
Calculate the sum or difference: ![x = -11](https://tex.z-dn.net/?f=x%20%3D%20-11)
Thurs, x = -11

The quotenet is -5 because if you divide 10 by a negitive the quotent will be negitive.
Answer:
A_16x20=320
Step-by-step explanation:
Esto se puede hacer fácilmente de 2 formas.
1) 20 se puede dividir en un múltiplo de 10 y luego multiplicar
16 x 20 =16 x 10 x 2 = 160 x 2 = 320
2) Uso de cero.
Cualquier cosa multiplicada por cero da un cero y luego multiplicar el otro número da el resultado.
16 x 20 = (16 x 2) * 10 = (32) 10 = 320
Así que separamos el cero añadiéndole un 1, lo que lo convierte en 10 y obtenemos el mismo resultado.
This can be easily done in 2 ways .
1) 20 can be broken into a multiple of 10 and then multiplied
16 x 20 =16 x10 x 2=160x 2= 320
2) Use of zero.
Anything multiplied with zero gives a zero and then multiplying the other number gives the result.
16 x 20 = (16x 2) *10= (32)10= 320
So we separated the zero by adding a 1 to it thus making it 10 and we get the same result.
In order to find this answer, you need to know how much miles he drives on one hour.
The steps are down below
1. Find how much he drives in one hour
754/ 13=58
he drives 58 miles every hour
now you do 464/ 58 which you get 8.
Thefore the answer is 8.
I hope this helped.
If it is wrong, blame me i have not done them in a long time.
Answer:
14
Step-by-step explanation:
In point-slope form, the equation with slope -7 through point (3, 0) can be written ...
y = -7(x -3) +0
y = -7x +21 . . . . . eliminate parentheses
Here, we can see m=-7 and b=21, so ...
m+b = -7+21 = 14
