The system of equations has no solution:<br> y=2/3x-5<br> 4x - 6y = 30<br> true or false?
Serjik [45]

1. y = 2/3x - 5

2. 4x - 6y = 30

Divide 2. by 2

3. 2x - 3y = 15

Substitute 1. into 3.

4. 2x - 3(2/3x - 5) = 15

5. 2x - 2x + 15 = 15

6. 15 = 15

False. There are an infinite number of solutions.

AB =2DC

So, DC=AB/2

Now, AB/AC=DE/DC

AB/28=13/(AB/2)

AB²=13×28×2

AB=√728

AB=26.98

now, DC=AB/2

=13.4

If a tank holds 4500 gallons of water, which drains from the bottom of the tank in 50 minutes, then Toricelli's Law gives the vo
disa [49]

Answer:

The response to this question can be defined as follows:

Step-by-step explanation:

v =4500 (1-\frac{t}{50})^2\\\\\to \frac{dV}{dt}= 9000 (1- \frac{t}{50})(\frac{1}{50})\\\\

          = 180 (\frac{50-t}{50})\\\\= 3.6(50-t)\\\\

For point a:

t=5\\\\V'=3.6\times 45 = 162\\\\ans= - 162\ \frac{gal}{min}\\\\

For point b:

t=10\\\\V'=3.6\times 40 = 144\\\\ans= - 144 \ \frac{gal}{min}\\\\

For point c:

t=20\\\\V'=3.6\times 30 = 108\\\\ans= - 108 \ \frac{gal}{min}\\\\

For point d:

t=50\\\\V'=3.6\times 0 = 0\\\\ans= 0 \ \frac{gal}{min}\\\\
