Answer:

Step-by-step explanation:

y = 3x + 2

6x – 2y = 10

Ryan’s answer:

I solved by adding the equations. The solution is .

y = 3x + 2 → 3x + y = 2

6x – 2y = 10 → 3x – y = 5

6x = 7

x =

6x – 2y = 10 → 6 – 2y = 10

7 – 2y = 10

–2y = –3

y = -

Jesse’s answer:

I used matrices. The solution is .

Mark’s answer:

I graphed the equations. The lines are parallel and do not intersect, so there is no solution.

Answer:

3125 bacteria.

Step-by-step explanation:

We can write an exponential function to represent the situation.

We know that the current population is 100,000.

The population doubles each day.

The standard exponential function is given by:

[tex]P(t)=a(r)^t[/tex]

Since our current population is 100,000, a = 100000.

Since our rate is doubling, r = 2.

So:

[tex]P(t)=100000(2)^t[/tex]

We want to find the population five days ago.

So, we can say that t = -5. The negative represent the number of days that has passed.

Therefore:

[tex]\displaystyle P(-5)=100000(2)^{-5} = 100000 \Big( \frac{1}{32}\Big) = 3125 \text{ bacteria}[/tex]

However, we dealing within this context, we really can't have negative days. Although it works in this case, it can cause some confusion. So, let's write a function based on the original population.

We know that the bacterial population had been doubling for 5 days. Let A represent the initial population. So, our function is:

[tex]P(t)=A(2)^t[/tex]

After 5 days, we reach the 100,000 population. So, when t = 5, P(t) = 100000:

[tex]100000=A(2)^5[/tex]

And solving for A, we acquire:

[tex]\displaystyle A=\frac{100000}{2^5}=3125[/tex]

So, our function in terms of the original day is:

[tex]P (t) = 3125 (2)^t[/tex]

So, it becomes apparent that the initial population (or the population 5 days ago) is 3125 bacteria.

Answer:

We can express the question in a exponential function

The current population is 100,000.

The population doubles each day.

The exponential function is given by: P(t)=a(r)^t

The current population is 100,000, a = 100000.

The rate is doubling, r = 2.

P(t)=100000(2)^t

As we know that the bacterial population had been doubling for 5 days. Let A represent the initial population. So, the function is:

P(t)=A(2)^t

After 5 days, the population reaches 100,000. So, when t = 5, P(t) = 100000:

100000=A(2)⁵

Now solving for A, we get

A=(100000)/(2⁵)=3125

So, the function in terms of the original day is:

P (t) = 3125 (2)^t

Hence, the initial population is 3125 bacteria.

Answer:

I'm pretty sure A is the correct answer :)

(x-2)(x^4+3) is a polynomial

Answer:

1. 4x(x^2+5x+4)

2. 2x^2(6x^2+13x-8)

3. 2(5x^2+24x-5)

Step-by-step explanation:

1.

The common factor between all the monomials is 4x, so we divide each by 4x.

2.

The common factor between all the monomials is 2x^2, so we divide each by 2x^2.

3.

The common factor between all the monomials is 2, so we divide each by 2.

Answer:

x=5

Step-by-step explanation:

So first simplify the equation

√5x-6=-1

Add 6 on both sides

√5x=5

now since it being squared with btoh numbers having a 5, x is 5

Answer:

Step-by-step explanation:

[tex] \sqrt{5x} - 6 = - 1[/tex]

[tex] \sqrt{5x} = 5[/tex]

[tex]5x = 25[/tex]

[tex]x = 5[/tex]

Answer:

-3,-6

-2,-3

3,12

4,15

5,18

Step-by-step explanation:

To find each output {f(x)}, multiply each input (x) by 3, then add 3 to the product.

Answer:

in order from top to bottom, the answers are -6. -3. 12. 15. and 18

step by step explanation:

to do this you take the equation f(x)=3x+3 and take substitute the number in the x column where it says x.

example: f(x)=3(-3)+3

after that you solve the equation. -3×3 is -9 and then -9+3= -6

1. Chlorophyll is the pigment in plats that absorbs light. If plants were not able to absorb light they would not be able to do photosynthesis and they would not be able to survive. Plants are green because green light is the only wavelength not absorbed by the chlorophyll in plants so this is the color o light that gets reflected back to our eyes.

2.Plants are essential to life on Earth because they convert energy from the sun into stored energy which can be used by animals. They are also essential because one of the outputs of photosynthesis is oxygen which is necessary for breathing and sustaining life. Animals need plants because plants produce oxygen and because animals are unable to convert solar energy into usable energy themselves so they need plants to convert solar energy into chemical energy, which is done through the process of photosynthesis. Animals need this so that animals can use the stored energy that is produced by the plants.

Answer:

The measure of angle DPA is 39°

Step-by-step explanation:

step 1

Find the value of x  we know that  arc AB+arc BC+arc CD+arc DA=360°

substitute the values

(5x+10)°+(x+1)°+3x°+(3x+25)°=360°

Solve for x

(12x+36)°=360°

12x=360°-36°

x=324°/12=27°

step 2  Find the measure of angle DPA

we know that  The measurement of the external angle is the semi-difference of the arcs which comprises

m∠DPA=(1/2)[arc DA-arc BC]

arc DA=3(27)+25=106°

arc BC=27+1=28°

substitute the values

m∠DPA=(1/2)[106°-28°]=39°

Answer:

BC = 50

Step-by-step explanation:

AB and AD are congruent, thus

AB = AD, that is

5x + 10 = 3x + 18 ( subtract 3x from both sides )

2x + 10 = 18 ( subtract 10 from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Thus

BC = 12x + 2 = 12(4) + 2 = 48 + 2 = 50

[tex]\theta=54.2^\circ[/tex]

Step-by-step explanation:

Right Triangles

The ratios of the sides of a right triangle are called trigonometric ratios.  Each acute angle has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

The tangent ratio is defined as:

[tex]\displaystyle \tan\theta=\frac{\text{opposite side}}{\text{adjacent side}}[/tex]

The opposite side is 25 and the adjacent side is 18, thus:

[tex]\displaystyle \tan\theta=\frac{25}{18}=1.389[/tex]

The angle is calculated by using the inverse tangent function:

[tex]\theta=\arctan 1.389[/tex]

[tex]\boxed{\theta=54.2^\circ}[/tex]

Answer:

The unit cost is: 0.02 $ per sticker

Step-by-step explanation:

Given

Total stickers = 75

The cost of 75 stickers = 1.50 (let say in $)

To determine

The unit cost per sticker

The unit cost per sticker can be calculated by dividing the total cost by the number of total stickers, so

Unit cost = 1.50 / 75

                = 0.02 $ per sticker

Therefore, the unit cost is: 0.02 $ per sticker

Answer:

g(x) = [tex]\frac{x+3}{x-3}[/tex]

Step-by-step explanation:

From the picture attached,

Given function is,

f(x) = x + 1

We have to find the value of g(x) if the composite function has been given as,

f[g(x)] = g(x) + 1 = [tex]\frac{2x}{(x-3)}[/tex]

g(x) = [tex]\frac{2x}{(x-3)}-1[/tex]

      = [tex]\frac{2x-(x-3)}{(x-3)}[/tex]

      = [tex]\frac{(x+3)}{(x-3)}[/tex]

Therefore, g(x) = [tex]\frac{x+3}{x-3}[/tex] will be the answer.
