Answer:

x = 4

y = 6

Step-by-step explanation:

3x + 4y = 36

3x + 4(-1/2x + 8) = 36

3x - 2x + 32 = 36

x + 32 = 36

x + 32 - 32 = 36 - 32

x = 4

y = -1/2x + 8

y = -1/2(4) + 8

y = -2 + 8

y = 6

Micheal is building an iron man from junk in his dad's yard: he starts with a prototype of 1.8m high:he wants to make it 120m hi
finlep [7]
Ok, so the first thing you need is how much taller the second model is than the first model the way we do that is we take the second model height and divide that by the first model height 120/1.8=66.667 or 66 2/3 Second now we need to multiply the length of the middle finger by 66.667
6*66.667=400 cm now we just need to convert 400 cm to meters and since there are 100 cm in a meter we can do this 400/100=4 me so the answer is the little finger needs to be 4 meters long.

Find the particular solution of the differential equation dy + 7y = 6 satisfying the initial condition y(0) = 0. Answer: y= Your
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

We have the equation y'+7y=6 with the initial condition y(0)=0. It is not difficult to notice that this is a linear equation, which has the general expression

y'+P(x)y=Q(x).

The solution of this equation is expressed by a general formula:

y(x) = \exp\left(-\int P(x)dx\right)\left(\int Q(x)\exp\left(-\int P(x)dx\right) +C\right).

In the particular case of our equation, we have

P(x)=7

Q(x)=6.

Then, we must calculate the integrals

\int 7dx = 7x that implies

\exp\left(-\int P(x)dx\right) = e^{-7x},

and

\int 6e^{7x}dx = \frac{6}{7}e^{7x}

Then,

y(x) = e^{-7x}\left(\frac{6}{7}e^{7x} +C\right) = \frac{6}{7} + Ce^{-7x}.

In order to obtain the value of the constant we substitute the initial condition

0=y(0) = \frac{6}{7} + C that implies C=-\frac{6}{7}

Therefore,

y(x) = \frac{6}{7}-\frac{6}{7}e^{-7x}.
