Answer:

(4,-2)

Step by Step Explanation:

Given equations are

y=x-6 eq(1)

3x+2y=8 eq(2)

Subtitute eq(1) into eq(2) we get

3x+2(x-6)=8

3x+2x-12=8

5x-12=8

Adding 12 on both side of equation we get

5x-12+12=8+12

5x=20

Dividing by 5 on both sides of equation we get

5x/5=20/5

x=4

Putting the value of in eq(1) we get

y=4-6

y=-2

The solution is (4,-2).

Answer:

The answer is (4,-2)

Step-by-step explanation:

y=x-6

3x+2y=8

3x+2(x-6)=8

3x+2x-12=8 Combine like terms

3x+2x-12+12=8+12 add 12 to both sides then combine

5x=20→ x=4

then plug it in to y=x-6→y=4-6→y=-2

Researchers recorded that a certain bacteria population declined from 200,000 to 900 in 18 hours. At this rate of decay,

salantis [7]

Answer:

9,942 bacteria were there at 10 hours.

Step-by-step explanation:

Equation for population decay:

The equation for population decay, after t hours, is given by:

$P(t) = P(0)(1-r)^t$

In which P(0) is the initial population and r is the decay rate, as a decimal.

Researchers recorded that a certain bacteria population declined from 200,000 to 900 in 18 hours.

This means that $P(0) = 200000$ and that when $t = 18, P(t) = 900$ . So we use this to find r.

$P(t) = P(0)(1-r)^t$

$900 = 200000(1-r)^{18}$

$(1-r)^{18} = \frac{900}{200000}$

$\sqrt[18]{(1-r)^{18}} = \sqrt[18]{\frac{900}{200000}}$

$1 - r = (\frac{900}{200000})^{\frac{1}{18}}$

$1 - r = 0.7407$

$P(t) = P(0)(1-r)^t$

$P(t) = 200000(0.7407)^t$

At this rate of decay, how many bacteria was there at 10 hours?

This is P(10). So

$P(10) = 200000(0.7407)^{10} = 9941.5$

Rounding to the nearest whole number:

9,942 bacteria were there at 10 hours.
