Answer:

C. Yes, by distributive property

Step-by-step explanation:

Distributive property states that 3 can be distributed to all of the terms inside of the parentheses, namely x and -2. 3x + 3(-2) = 3x-6

Answer:

multicellular organisms  = 14

Step-by-step explanation:

given data

multicellular organism = 625 sq feet

total = 8750 sq feet

solution

we will gethere

as we know that 1 multicellular organism  =  625 sq feet  

so

we get here  multicellular organisms that is

multicellular organisms = ( 8750 ×1 ) ÷ 625

multicellular organisms  = 14

Answer:

y=2x is it I think because the y intercept is the origin

Answer: 153

Step-by-step explanation:

When we have a group of N elements, the total number of combinations of K elements ( K ≤ N) is:

[tex]C (N, K) = \frac{N!}{(N-k)!*K!}[/tex]

Where N! = N*(N - 1)*(N - 2)*...*2*1

In this case, we have a group of 18 people (then N = 18) and we want to see how many different combinations of 2 we can make (K = 2).

Using the above equation we get:

[tex]C(18, 2) = \frac{18!}{(18 - 2)!*2!} = \frac{18!}{16!*2!} = \frac{18*17}{2} = 9*17 = 153[/tex]

There are 153 different ways in which the manager can do this.

Answer:

124.1 m

Step-by-step explanation:

Given that:

Depth of mammoth cave = - 124.1 meters

To travel to the bottom of the cave, hence, the hiker is at the maximum depth.

Since the depth of the cave is - 124.1 m and the hiker has traveled down tonthe bottom and hence covered the total depth. Then thebhiker must have descended by the same value corresponding to the depthnifnthe cave = 124.1 meters

Answer:

  reasonable range: 0 ≤ y ≤ 5.5

Step-by-step explanation:

Unless the balloons are being launched from a building or the edge of a cliff, we generally expect f(x) ≥ 0. This limits the "reasonable range" to ...

  0 ≤ y ≤ 5.5

Answer:

40! Seconds

Step-by-step explanation:

Calculation for After how many seconds will the two fish tanks have the same amount of water

First step

Based on the information given let the equation be :

150-1/2x=120+1/4x

Second step

Now let solve for x which means that x will be the number of second by multiplying both side by 4

4(150-1/2x)=4(120+1/4x)

=600-2x=480+x

Third step

Let Add 2x on both side

600=480+3x

Third step

Let Subtract 480 on both side

600-480=480-480+3x

120=3x

Last step is to divide both side by 3

120/3=3x/3

40=x

Hence:

x=40 seconds

Therefore After 40 seconds the two fish tanks will have the same amount of water.

Answer:

in y=mx + b, b is the y intercept. Sp answer choice d.

Answer:

B and E

Step-by-step explanation:

They have different slopes so of course they will have to intersect at least 1 time. And if they were curved, it would be more than 1. But these are lines so it would be just 1 intersection. So B is one of the answers.

The solutions of the system are x = 0 and y = 2

I hope this helped, please mark me brainliest!

Step-by-step explanation:

y = 2x + 2 and y = 6x + 2

=> 2x + 2 = 6x + 2

=> 2x = 6x

=> 4x = 0, x = 0.

Therefore y = 2(0) + 2 = 2.

The point of intersection is (0, 2).

Hence there is exactly 1 point of intersection and exactly 1 real solution. (B and E)

Answer:

  3.88%

Step-by-step explanation:

The probability that 1 is defective and 3 are not (out of four) is ...

  P(1 of 4) = 4(0.01)(0.99)^3 ≈ 0.0388 = 3.88%

__

The multiplier of 4 comes from the number of ways that 1 can be chosen from 4.

Answer:

x<±1 and x< -3

Step-by-step explanation:

Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality

x^2-1/3x+9<0

x^2-1/3x+9 (3x+9)²<0*  (3x+9)²

(x^2-1)(3x+9) < 0

x²-1 < 0 and 3x + 9 <0

x²-1 < 0

x²<1

x<±√1

x<±1

Also 3x + 9 <0

3x < -9

x < -9/3

x < -3

Hence the required values of x are x<±1 and x< -3

Answer:

0.667

Step-by-step explanation:

Answer:  2 vertices

The two vertices in question are (2,0) and (5,0). These are points A and D. These two points are on the x axis, which is the line of reflection. Any point on a line of reflection does not move.

The points (0,-3) and (3,-3) are not on the line of reflection, so they do move and are reflected to another location. Refer to the diagram below.

Step-by-step explanation:

Answer:

Each bottle of juice costs $1.34.

Step-by-step explanation:

From the information given, the equation would indicate that the total cost is equal to the price per bag of popcorn for the number of bags plus the price per pack of juice bottles for the number of packs.

Total cost=(1.68*1)+15x

Total cost=1.68+15x

Now, you can replace the total cost with $21.78 and solve for x:

21.78=1.68+15x

21.78-1.68=15x

20.1=15x

x=20.1/15

x=1.34

According to this, the answer is that each bottle of juice costs $1.34.
