What is the answer to this

Mathematics
1 answer:
lukranit [14]3 years ago
8 0

Answer:

B.

Step-by-step explanation:

5x + y = 3

10x + 2y = - 3

y = - 5x + 3

2y = - 10x - 3

y = - 5x + 3

y = - 5x - 3/2

These lines have the same slope, but different y-intercept, so they are parallel.

The population of a bee hive is growing with a monthly percentage rate compounded continuously. The population doubles in 3 mont
agasfer [191]

Answer:

r = \frac{\ln{2}}{3}

Step-by-step explanation:

The exponential growth function is:

P(t) = P(0)e^{rt}

In which P(t) is the population after t months, P(0) is the initial population and r is the monthly percentage rate.

The population doubles in 3 months.

This means that P(3) = 2P(0)

We use this to find r.

P(t) = P(0)e^{rt}

2P(0) = P(0)e^{3r}

e^{3r} = 2

\ln{e^{3r}} = \ln{2}

3r = \ln{2}

r = \frac{\ln{2}}{3}

Slope intercept form of 12x-y=4
Nata [24]

Hey there! :)

Please keep in mind that slope-intercept form is : y=mx+b ; where m=slope, b=y-intercept

Using this, we can isolate y in our original given equation.

12x - y = 4

Start off by subtracting 12x from both sides.

-y = -12x + 4

Divide both sides by -1.

-y ÷ -1 = (-12x + 4) ÷ -1

Simplify!

y = 12x - 4

Therefore, using the slope-intercept form, we can come to the conclusion that because 12 is located in the "m" slot and "m=slope" then 12 is our slope. In addition, -4 is our y-intercept because it is located on the y position.

Slope = 12

Y-intercept = -4

<em>Hope I helped! :) </em>
