I need help it says what could I change in this polynomial to make them like terms.
[tex] {2x}^{2} + 5x - 6y + 2y - 7[/tex]
​

Answer:

y= 9 ( 5 dollars bill)

x=10 ( one dollar bill)

Step-by-step explanation:

let x be the one dollar bill and y the 5 dollar bill

x+y=19 ⇒ x=19-y

x+5y=55 ( solve by substitute x=19-y)

19-y+5y=55

4y=55-19

4y=36 ⇒ y=36/4

y= 9 ( 5 dollars bill)

x+y=19

x+9=19

x=19-9

x=10 ( one dollar bill)

check :

x+5y=55

10+5(9)=

10+45 = 55 dollars

[tex]\text {Simplify the Equation:}[/tex]

Hey there!

[tex]2(x+8)>18+x-4[/tex]

In our first step, we will need to simplify the inequality.

[tex]2x+16>x+14[/tex]

Now we have to subtract x from both sides of the inequality.

[tex]2x+16-x>x+14-x=x+16>14\\x+16>14[/tex]

In our last step, we will need to subtract 16 from both sides of the inequality.

[tex]x+16-16>14-16=x>-2\\x>-2\text{(ANSWER)}[/tex]

Answer:

1*3*3*3*3*3*3=729. For each term you multiply the previous term by three.

Answer:

2187

Step-by-step explanation:

To find the 8th term, we can find and use the explicit formula.

The standard form of the explicit formula for a geometric sequence is:

[tex]x_n=a(r)^{n-1}[/tex]

Where a is the initial term, r is the common ratio, and n is the nth term.

From the sequence, we can see that the first term is 1, and each term is 3 times the previous term. Thus, the common ratio is 3.

Substituting these into our equation, we will have:

[tex]x_n=1(3)^{n-1}\\x_n=(3)^{n-1}[/tex]

So, to find the 8th term, substitute 8 for n:

[tex]x_8=(3)^{8-1}[/tex]

Subtract:

[tex]x_8=(3)^7[/tex]

Evaluate:

[tex]x_8=2187[/tex]

So, the 8th term is 2187.

And we're done!

The approximate monthly decrease in value is $255.2

A percentage is a number or ratio expressed as a fraction of 100.

Given,

Value of the car = $22000

Loss percentage of value per year = 13.9%

Loss percentage of value per month =[tex]\frac{13.9}{12}[/tex] =1.16%

Decrease in value per month = [tex]22000(\frac{1.16}{100})[/tex]= $255.2

Hence, the approximate monthly decrease in value is $255.2

Given :

Number of paintings Adrian created each month for the last year are :

4, 5, 2, 1, 0, 3, 2, 4, 3, 2, 7, 5 .

To Find :

The median of the set of data .

Solution :

To find the median we should arrange the numbers in ascending order .

So , 0, 1, 2, 2, 2, 3, 3, 4, 4, 5, 5, 7 .

Now , median for odd is the middle term but for even numbers it is the average of middle two terms .

So ,

[tex]Median =\dfrac{3+3}{2}\\\\Median =3[/tex]

Therefore , the median of the set of data is 3 .

Hence , this is the required solution .

Answer:

28.26 miles

Step-by-step explanation:

Area= pi times radius squared

diameter is twice the radius so 6÷2=3miles

3 miles is the radius

So A= 3.14 × 3²

= 28.26

Formula: A = πr²

Divide to find the radius.

6 / 2 = 3

Solve using the values we are given and solved for.

A = π(3)²

A = 9π

A ≈ 28.26

The question is not clearly stated, below is the clearly stated question and answer:

A customer wants you to enlarge a photo to 2 3/4 its current height. The photo’s current height is 3 1/4 inches. What should its enlarged height be, in inches?

Answer:

[tex]Enlarged\ height = 8\frac{15}{16}\ inches[/tex]

Step-by-step explanation:

[tex]current\ height\ =\ 3\frac{1}{4} = \frac{13}{4} \\ magnification\ factor = 2\frac{3}{4} = \frac{11}{4} \\Magnification (enlargement)\ =\ (magnification\ factor) \times (current\ height)\\Magnification\ =\ \frac{11}{4} \times \frac{13}{4}\\ Magnification\ =\ \frac{143}{16}[/tex]

Next, we will concert from the improper fraction to a mixed fraction:

when 143 is divided by 16, there will be 8 whole numbers and a remainder of 15, hence, the mixed fraction is:

[tex]\frac{143}{16} = 8\frac{15}{16}[/tex] (Alternatively, a scientific calculator can be used)

Therefore, enlarged height [tex]= 8\frac{15}{16}\ inches[/tex]

y = -1.50x + 15, Domain is from 0 to 10

Step-by-step explanation:

First, look at the question carefully and highlight all the words that are important. We know that the 15 dollar giftcard is important, and we know that each song costs 1 dollar and 50 cents is important. We will make an equation out of this information. Since she is spending money, the value of X will be negated. She starts out with 15 dollars, so that will be our y-intercept. From this, the equation is y = -1.50x + 15. Next, let's look at the domain. We can see that the question asks for a suitable domain, not the domain of the function. Since she didn't have more than 15 dollars from her gift card, any domain from negative infinity until 0 will be crossed out. The x-intercept of this equation is 10, so any value above 10 will be crossed out since you cannot spend more money than you were given. The domain would now be from 1 to 10.

Answer:

D

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Domain is the furthest X value while Range is the furthest Y value.

Step-by-step explanation:

The original amount of dimes Marcy had before sharing with Jaunita is 52.

Let's break down the given information step by step to determine the original number of dimes Marcy had.

Marcy gave Juanita as many dimes as Juanita had.

After this transaction, Juanita now has 26 dimes, and Marcy has x - 26 dimes, where x is the original number of dimes Marcy had.

Juanita gave Marcy as many dimes as Marcy had left.

After this transaction, Marcy now has 20 dimes, and Juanita has 26 - 20 = 6 dimes remaining.

From the above information, we can set up the following equation:

x - 26 = 20 + 6

Simplifying the equation:

x - 26 = 26

Adding 26 to both sides:

x = 52

Therefore, the original amount of dimes Marcy had is 52 dimes.
