balance the equation show all 6 steps. 6+a=20

Answer:

The data can be modeled using linear equatins, because there's the same amount of population for fish A (+20 per year) and fish B (+30 per year) every year.

Step-by-step explanation:

step 1. the x intercepts (called zeros) are where y = 0 or where the graph is on the x axis

step 2. the zeros are -3, 0, 2, 5.

step 3. therefore there are 5 intervals

step 4. ( ,-3) - f(x) = "-"

step 5. (-3, 0) - f(x) = "+"

step 6. (0, 2) - f(x) = "+"

step 7. (2, 5) - f(x) = "-"

step 8. (5, ) - f(x) = "+".

A function assigns the values. The x-intercept for the given function is -3, 0, 2, and 5.

A function assigns the value of each element of one set to the other specific element of another set.

The given function can be rewritten as,

f(x) = x²(x-5)(x+3)³(x-2)

f(x) = (x-0)² (x-5) (x+3)³ (x-2)

Now, the value of x in the given function, or the x-intercept can be found by substituting the value of the factors of function as 0.

0 = (x-0)² (x-5) (x+3)³ (x-2)

(x-0)² = 0

x = 0

x-5 = 0

x = 5

x+3 = 0

x = -3

x - 2 = 0

x = 2

x = -3, 0, 2, 5

Hence, the x-intercept for the given function is -3, 0, 2, and 5.

Answer:

x = -8

Step-by-step explanation:

4x - (9 - 3x) = 8x - 1

remove parenthesis

4x - 9 + 3x = 8x - 1

add 9 to both sides

4x + 3x = 8x + 8

subtract 8x from both sides

-x = 8

x = -8

The solution to the equation 4x - (9 - 3x) = 8x -1​ is x = -8

From the question, we have the following parameters that can be used in our computation:

4x - (9 - 3x) = 8x -1​

Open the brackets

So, we have

4x - 9 + 3x = 8x - 1

Evaluate the like terms

So, we have the following representation

7x - 9 = 8x - 1

Next, we have

8x - 7x = 1 - 9

So, we have

x = -8

Hence, the solution is x = -8

Hello there! :)

Perpendicular lines have slopes that are opposite reciprocals. It means that if we have a number, we flop it over and make it negative.

We have 1/6.

Answer: No, I wouldn't because he didn't do what he was told.

Step-by-step explanation: Using Matt's survey we draw a Venn Diagram.

Venn Diagram is a diagram used to show the logical relationship between two or more set of items.

The survey Matt did is represented below.

To construct the diagram:

1) Create 3 sets of data (represented by the circles) intersecting each other;

2) The space where the three intersect is the number of people surveyed that preferred all types. So, we write 7 in the space;

3) According to the research, 19 preferred comedies and variety. But there are already 7 in the intersect, so, 12 has those preferences;

4) Following the same logic, 14 preferred variety and drama. Then, 7 has those preferences;

5) And, 8 preferred comedy and drama;

6) Now, to determine how many of them has an exclusive preference, we take the data and subtract the already known values:

7) 5 don't like any of the types, so it is represented outside the three circles;

After creating the Diagram, we can determine how many people answered the poll:

total = 31 + 12 + 12 + 8 + 7 + 7 + 22 + 5

total = 104

Therefore, as a personnel manager, I wouldn't hire Mr. Matic because he was supposed to poll 100 people but he polled 104 people.

create a proportion 72/348 = 32/x

Step-by-step explanation:

x = 1682

1682 ÷ 12 = 140.1

The length of the tree’s shadow that will allow the tree to be cut down will be 150.5 inches.

What are ratio and proportion?

A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.

A lumber mill needs one more tree cut down that is at least 29 feet long. The person cutting down the tree is 6 feet 2 inches tall.

            29 feet = 348 inches

6 feet 2 inches = 74 inches

Using shadows to determine whether a tree is tall enough, the person stands next to the tree and measures the length of his shadow as 32 inches.

Then the length of the tree’s shadow that will allow the tree to be cut down will be

Let x be the tree’s shadow. Then we have

x / 348 = 32 / 74

x = 150.486

x ≅ 150.5 inches

The answer is C.

A is incorrect, because if you solve it, you would have [tex]x^2-121[/tex]

B is incorrect, because if you solve it, you would have [tex]121x-x^2[/tex]

5x-2x

Step-by-step explanation:

4x-x = 3x

so,

5x-2x = 3x

The equivalent expression would be; 5x-2x

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

We are given that the expression as; 4x - x

We need to find an equivalent expression.

Therefore, solving further;

4x-x = 3x

Thus, we can also create one expression as;

5x-2x = 3x

Answer:

1) 202.52

2) P107089

Step-by-step explanation:

Compound interest is calculated as

A = P (1 + r/n)^(nt), where

A = compounded interest

P = present value

r = interest

n = number of times interest applied

t = time taken

A = 200 (1 + 0.25%/30)^(30 * 5)

A = 200 (1 + 8.3*10^-5)^150

A = 200 * 1.0126

A = 202.52

Present Value Annuity Due is usually given by the formula

P = c*((1-(1+ i)^(-n))/i)*(1 + i ), where

P is the present value

C is the Cash flow per period

i is the interest rate and

n is the number of payments

P = 10000*((1-(1+ 12/1200)^(-1*12))/(12/1200))*(1+12/1200)

P = 113676

Also, it's worthy of note that

Effective Annual Rate = [(1 +stated rate/no. of compounding periods) ^no of compounding periods - 1]* 100

EAR = ((1+12/(12*100))^12-1)*100

EAR = 12.68%

And lastly, the

Future value = present value*(1+ rate)^time

113676 = Present value*(1+0.1268)^0.5

Present Value = 113676 / 1.1268^0.5

Present Value = 113676 / 1.0615

Present value = 107089
