= –5x + 30 x = 10 What is the solution to the system of equations? (–20, 10) (10, –20) (10, 4) (4, 10)

Answer:

The final value of the stock is $3,996.66

Step-by-step explanation:

Percentage Change

The x% of a number N is calculated as x*N/100. If there is an increase, that number is added to the original value, then the new value is:

N'=N+x*N/100

Operating:

N'=N(1+x/100)

That formula makes it easier to find the new values of increasing quantities. When the percentage is for decreasing, then the formula becomes:

N'=N(1-x/100)

The original value of the stock is N1=3,789. The first change is an increase of 6%, then the new value is:

N2=3,789(1+6/100)=3,789*1.06=$4,016.34

The stock value now decreases by 7%:

N3=4,016.34(1-7/100)=4,016.34*0.93=$3,735.20

Finally, the value increases again by 7%:

N4=3,735.20(1+7/100)=3,735.20*1.07=$3,996.66

The final value of the stock is $3,996.66

Answer:

x=4

Step-by-step explanation:

If price  of a sweater was reduced from $20 to $12 then the percentage was the price of the sweater reduced is 40%.

percentage, a relative value indicating hundredth parts of any quantity.

Given that the price of a sweater was reduced from $20 to $12.

Original price is 20.

new price is 12.

We have to find the how much  percentage was the price of the sweater reduced.

To do this we have to find the difference between prices over the original price and multiply with 100.

Percentage = 20-12/20×100

=8/20×100

=40%

Hence, if price  of a sweater was reduced from $20 to $12 then the percentage was the price of the sweater reduced is 40%.

Step-by-step explanation:

Im sorry if its wrong, if its right can you mark me brainliest?

Let, number of games played is n and sum of their points are x.

So, [tex]177=\dfrac{x}{n}[/tex]    

Now, In his next game he obtained a score of 199, which caused his average to increase to 178.

[tex]178=\dfrac{x+199}{n+1}[/tex]

Now equations are :

x = 177n    ...1)

x + 199 = 178( n + 1 )

x = 178n - 21  ...2)

Solving eq 1 and 2 , we get :

x = 3717 and n = 21 .

Now, new average is 183.

Let, point scored in last game is y.

So,

[tex]183 =\dfrac{x+y}{n+1+1}\\\\183 = \dfrac{3717+y}{23}\\\\y = 183\times 23 - 3717\\\\y=492[/tex]

He required 492 points which is greater than the maximum i.e 300.

Therefore, it is not possible for Fred.

Hence, this is the required solution.

Step-by-step explanation:

one possible way to do this is to simply observe that 12*2 =24, so 5 shares must also be multiplied by 2

another way is to set up a proportion, 5/12=x/24, cross multiply, 5*24=12x, solve for x, x=(5*24)/12=10

Answer:

[tex]a_n=112\left(-\frac{1}{4}\right)^{n-1}[/tex]

Step-by-step explanation:

Geometric Sequences

There are two basic types of sequences: arithmetic and geometric. The arithmetic sequences can be recognized because each term is found as the previous term plus a fixed number called the common difference.

In the geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

We are given the sequence:

112, -28, 7, ...

It's easy to find out this is a geometric sequence because the signs of the terms are alternating. If it was an arithmetic sequence, the third term should be negative like the second term.

Let's find the common ratio by dividing each term by the previous term:

[tex]\displaystyle r=\frac{-28}{112}=-\frac{1}{4}[/tex]

Testing with the third term:

[tex]\displaystyle -28*-\frac{1}{4}=7[/tex]

Now we're sure it's a geometric sequence with r=-1/4, we use the general equation for the nth term:

[tex]a_n=a_1*r^{n-1}[/tex]

[tex]a_n=112\left(-\frac{1}{4}\right)^{n-1}[/tex]

Answer:

a) after 12.59 days the revenue will be equal

b) u just have to graph it

the second one is

a) the two solutions are x=4 and x=-4

b) x=-4 is not reasonable because time can’t be negative

c) after four seconds, the heights will be equal

Step-by-step explanation:

After 12.59 days the revenue for each game is the same. The two solutions of the system equation b(t) and p(t) are 4 and -4, and -4 is not a reasonable solution because time never be negative and after 4 seconds the rocket and the ball reach the same height.

1)

Given :

Math Game --   [tex]\rm M(d) = x^2-9x-10[/tex]

Reading Game --   R(d) = 2x + 10

It is given that after 'x' number of days the revenue for each game is the same, that is:

[tex]\rm x^2 -9x-10=2x+10[/tex]

[tex]\rm x^2 -11x-20=0[/tex]

Simplify the above quadratic equation.

[tex]\rm x = \dfrac{11\pm \sqrt{11^2-(4\times -20)} }{2}[/tex]

[tex]\rm x = \dfrac{11\pm \sqrt{201} }{2}[/tex]

x = 12.59 days

So, after 12.59 days the revenue for each game is the same.

The graph of both the revenue function is attached below.

2)

Given :

[tex]\rm b(t) =- t^2-2t+36[/tex]

p(t) = -2t + 20

The solution of this system can be determined by equating both the above function.

[tex]\rm -t^2 - 2t +36 = -2t +20[/tex]

Simplify the above equation.

[tex]\rm t^2 =16[/tex]

t = 4 and -4

a) The two solutions of the system are 4 and -4.

b) -4 is the solution is not a reasonable solution because time never be negative.

c) After 4 seconds the rocket and the ball reach the same height.

Answer:

1/3

Step-by-step explanation:

If you want to write the fraction in its lowest terms, all you have to do is simplify!! Simplifying is easy; all you have to do is divide on the top and bottom of the fraction by the same number.

So, to simplify 6/18, figure out what the highest number is that can go into both numbers in the fraction. For this problem, the highest number is 6.

6 divided by 6 is 1.

18 divided by 6 is 3.

The simplified answer comes out as 1/3...you can also check it by multiplying 1 and 3 by 6.

1 multiplied by 6 is 6.

3 multiplied by 6 is 18.

So, 6/18 in lowest terms is 1/3!!

I hope you understood...have a great day :)
