I still dont understand slope can someone help?

Answer:

  1) 2^9 = 512

  2) 2^(3t) = 2^6 for t=2

Step-by-step explanation:

1) An exponent is used to signify repeated multiplication. Here, the factor 2 is repeated 9 times, so the expression can be written using an exponent as ...

  2^9

Using any of a variety of means, the value of this expression can be found to be ...

  2^9 = 512

__

2) Assuming the bacteria reproduce by multiplying by some factor in a given time, we can divide the original expression into 3 parts:

  (2×2×2) × (2×2×2) × (2×2×2)

If this represents the number after 3 hours, then the number after 2 hours is expected to be ...

  (2×2×2) × (2×2×2) = 2^6

That is, there will be (2 h)/(3 h) = 2/3 times as many multiplications by a factor of 2. (2/3)(9) = 6 will be the exponent for the number after 2 hours.

Step-by-step explanation:

Let the athletes be 3x and 2x.

Now, By the question we get,

(3x-12)/(2x+12) = 5/4

or, 12x-48= 10x+60

or, 2x = 108

so, x = 54

now

3x= 3×54= 162

2x = 2×54=108

The number of athletes were 162 in first team and 108 in second team originally.

x is the number of athletes on first team originally ( x > 12, x ∈ Nˣ )

y ----------------------------------------second------------------( y ∈ Nˣ )

The ratio of athletes in the two teams is 3:2

⇒      [tex]\frac{x}{y} =\frac{3}{2}[/tex]              (1)

After 12 athletes move from first team to second, the ratio is 5:4

⇒      [tex]\frac{x-12}{y+12} =\frac{5}{4}[/tex]         (2)

(1),(2)  ⇒ [tex]\left \{ {{\frac{x}{y} =\frac{3}{2}} \atop {\frac{x-12}{y+12} =\frac{5}{4}} \right. <=>\left \{ {{x=162} \atop {y=108}} \right.[/tex]

So: The first team originally has 162 numbers and the second team originally has 108 numbers

ok done. Thank to me :>

Answer:

domain is the values in x axis and the range is the value in y axis

Answer: the answer is x= 1

Step-by-step explanation:

So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50

our first step is Simplify both sides of the equation so:

11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:

(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)

**we know 11.5 + -11.5 will cancel each other since they are opposite**

so it will be 1.15x= 1.15

now the very last step is to divide 1.15x on both sides which gives us 1

The combine equation that represents the information in this problem is as follows;

n + d = 11

5n + 10d = 70

He has only nickel and dimes in his pocket. The total number of coins is 11 coins. The total cost is 70 cents.

let

n = number of nickels in his pocket

d = number of dimes in his pocket

1 nickel = 5 cents

1 dime = 10 cents

Therefore,

Therefore, the combine equation is as follows:

n + d = 11

5n + 10d = 70

Answer:

2.5x > 25

Step-by-step explanation:

1. 10 + 2.5x > 35

2. 10 + 2.5x - 10 > 35 - 10 (Subtracting 10 from both sides)

3. 2.5x +10 - 10 > 35 - 10 (Group like terms)

4. 2.5x > 35 - 10 (Simplify the arithmetic)

5. 2.5x > 25

Answer:

1.5 m

Step-by-step explanation:

Area = length * width

or we can say

Area = side1*side2

since they are the same we can say

Area = side * side

which also means area = side^2

so we have the area and we want the side, we need the inverse operation for squaring something. the inverse of squaring something is square rooting

so

sqrt(Area) = side

so

side = sqrt(2.25)

= 1.5 m

Answer:

1029.06

Step-by-step explanation:

You need to change 6% to a decimal

6% = .06

Then multiply .06 by 17,151

0.6 times 17,151 = 1029.06

To Check:

1029.06 out of 17,151

That's pretty much equal to 1/17

As a percentage, 1/17 is 6%
