Yes. 6x8 equals 48. 48x3 equals 144.

PLEASE ANSWER REALLY FAST I WILL MARK BRAINLIEST IF ANSWERED IN 2 MINUTES What is 15 x minus 3 y = 0 written in slope-intercept

Klio2033 [76]

Answer:

15x + 3y = 10.

Step-by-step explanation:

you have to solve for y.

isolate the variable.

15x + 3y = 10

start by subtracting 15x on both sides.

3y = -15x +10

then divide both sides by 3

y = -15/3x + 10/3

simplify.

y = -5x + 10/3

10/3 can be written as 3.33

or 3 and 1/3

Kim drives 156 miles from Rotherham to London.

masya89 [10]

No. See, you can take 60 out of 156 twice and you are left with 36. This means the drive would take about 2 hours and 36 minuets. 7+2=9 30+36=66 so then you add an our the time and you get that she would arrive a few minuets afterwards. (I'm sorry if I didn't explain this very well)

Use induction to prove: For every integer n > 1, the number n5 - n is a multiple of 5.

nignag [31]

Answer:

we need to prove : for every integer n>1, the number $n^{5}-n$ is a multiple of 5.

1) check divisibility for n=1, $f(1)=(1)^{5}-1=0$ (divisible)

2) Assume that $f(k)$ is divisible by 5, $f(k)=(k)^{5}-k$

3) Induction,

$f(k+1)=(k+1)^{5}-(k+1)$

$=(k^{5}+5k^{4}+10k^{3}+10k^{2}+5k+1)-k-1$

$=k^{5}+5k^{4}+10k^{3}+10k^{2}+4k$

Now, $f(k+1)-f(k)$

$f(k+1)-f(k)=k^{5}+5k^{4}+10k^{3}+10k^{2}+4k-(k^{5}-k)$

$f(k+1)-f(k)=k^{5}+5k^{4}+10k^{3}+10k^{2}+4k-k^{5}+k$

$f(k+1)-f(k)=5k^{4}+10k^{3}+10k^{2}+5k$

Take out the common factor,

$f(k+1)-f(k)=5(k^{4}+2k^{3}+2k^{2}+k)$ (divisible by 5)

add both the sides by f(k)

$f(k+1)=f(k)+5(k^{4}+2k^{3}+2k^{2}+k)$

We have proved that difference between $f(k+1)$ and $f(k)$ is divisible by 5.

so, our assumption in step 2 is correct.

Since $f(k)$ is divisible by 5, then $f(k+1)$ must be divisible by 5 since we are taking the sum of 2 terms that are divisible by 5.

Therefore, for every integer n>1, the number $n^{5}-n$ is a multiple of 5.

Liula [17]

Answer:

True

Step-by-step explanation:

Quasi-dynamic is a framework which accounts for inertial effects. In this we determine the long term behavior of state. It can be used to identify industry analysis where the industry is in a static state. Quasi static is a thermo-dynamic process that remains in internal equilibrium.
