Answer:

2x+y

Step-by-step explanation:

They have 2 bags containing "x" counters and 1 containing "y" counters. So 2 multiply the number of x since there are 2 bags + y because y also contains counters we need to add. (I'm pretty sure)

The percent increase from 200 to 460 is 130% increase

The numbers are given as

200 and 460.

460 is greater than 200

So, the percentage is an increment

The percentage increment is then calculated as

Percentage = (Final value - Initial value)/Initial value * 100%

Substitute the known values in the above equation

Percentage = (460 - 200)/200 * 100%

Evaluate the difference

So, we have

Percentage = 260/200 * 100%

Evaluate the quotient

So, we have

Percentage = 1.3 * 100%

Evaluate the product

So, we have

Percentage = 130%

Hence, the percent increase from 200 to 460 is 130% increase

Answer: B

Step-by-step explanation:

The two inequalities are:

y = 20x when x ≤ 6  and y = 15x when x > 6

The scenario given here is of a chicken that is being roasted. To solve this problem, we will take y as the time required to roast the chicken and x as the lbs of the chicken. (weight)

Now two different conditions are applied depending upon the lbs of the chicken the taken to roast the chicken will vary,

20min/lb for a chicken weighs as much as 6lb.

y = 20x when x ≤ 6

15 min/lb for a chicken weighs more than 6lb.

y = 15x when x > 6

The above two equations are the two inequalities that represent time needed to roast both the chicken.

The number of miles in a day at which the rental costs for Company A and Company B are the same will be 200 miles.

We are given that:

For Company A:

Fixed cost = $ 110

Variable cost = $ 0.20 per mile

For Company B:

Fixed cost = $ 70

Variables cost = $ 0.40 per mile

Let the number of miles in a day be x.

So, the equation for rental cost for company A will be:

Rental cost = 110 + 0.20 x

The equation for rental cost for company B will be:

rental cost = 70 + 0.40 x

Now, put both rental cost equal.

110 + 0.20 x = 70 + 0.40 x

0.40 x - 0.20 x = 110 - 70

0.20 x = 40

x = 40 / 0.20

x = 200 miles.

Therefore, the number of miles in a day at which the rental costs for Company A and Company B are the same will be 200 miles.

The inverse of the function is y = ( 1/5 )x - 6.

An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Consider the function,

y = 5x + 30

To find the inverse of the function we interchange x and y then find the equation for y.

Therefore, after interchanging x and y:

x = 5y + 30

Subtracting 30 from each side of the equation.

x - 30 = 5y + 30 - 30

x - 30 = 5y

Now, dividing the whole equation by 5

( x - 30 ) / 5 = 5y / 5

y = ( 1/5 )x - 30/ 5

y = ( 1/5 )x - 6

Therefore, the inverse of the function y = 5x + 30 is y = ( 1/5 )x - 6.

(-4x2-3x+6) + (6x2 - 2x + 1) = 2x2-5x + 7, the opposite of 2x2 + x-7 is -2x2 - X+ 7 and (-4x2+2x-1) - (-2x2 + 3x+6) = -2x-x - 7

1. (-4x2-3x+6) + (6x2 - 2x + 1)

= -4x2+ 6x2- 3x- 2x + 1+ 6

= 2x2- 5x + 7

Thus, adding gives us 2x2- 5x + 7 and thus (-4x2-3x+6) + (6x2 - 2x + 1) will be matched with the 5th equation.

2. opposite of: 2x2 + x-7

The opposite of 2x2 + x-7 can be found if we just reverse the signs of each of the term. This means that + becomes - and - becomes -

Thus the opposite is: -2x2 - X+ 7

Thus, it will be matched with the second option.

3. (-4x2+2x-1) - (-2x2 + 3x+6)

= -4x2+2x-1 + 2x2 - 3x - 6

The recursive formula for sequence 1,4,9,16, . . .  is a(n) = 2 a(n-1) - a(n-2) + 2

The recursive formula of a sequence is a formula that relates the nth term of the sequence with the preceding term(s), (n-1)th, (n-2)th, and so on.

The given sequence is: 1,4,9,16, . . .

So, we must ask ourselves:

How can we get 4 from 1?

How  can we get 9 from 4 and 1?

and so on.

Notice that:

4 = 1 + 3

9 = 4 + 5

16 = 9 + 7

Notice that the differences (3, 5, 7) increase by 2.

Therefore, we can write:

4 = 1 + 3

  = 1 + (1 - 0) + 2

9 = 4 + (4 - 1) + 2       (9 is a(3), and 4 is a(2))

a(3) = a(2) + a(2) - a(1) + 2

       = 2 a(2) - a(1) + 2

16 = 9 + (9 - 4) + 2

a(4) = a(3) + a(3) -a(2) + 2

a(4) = 2 a(3) - a(2) + 2

Continue this process, we get:

a(n) = 2 a(n-1) - a(n-2) + 2

The found value are-

A straight line's general equation is y = mx + c, in which m is the gradient and y = c is the value at which the line intersects the y-axis. This number c is known as the y-axis intercept.

Now, as per the given question;

The general equation of the line is given as;

y = mx + b

Each point (x,y) of the line is moved to the point (x+a, y+b) by the translation:

(x,y) ---> (x+a, y+b)

We find the original line's x and y intercepts:

Put y=0 in general equation of the line

⇒mx+b = 0

⇒x = −b/m

When, x=0

⇒y = m⋅0 + b

⇒ y = b

A, (0,b) and B( -b/m, 0)

We find the translational coordinates of the points A,B:

A(0,b) ---> A′ (0+a,b+b)

A(0,b) ---> A′ (a,2b)

And,

B( -b/m, 0) ----> B'( -b/m + a, 0 + b)

B( -b/m, 0) ----> B'( -b/m + a, b)

To find the equation of the line's translation, we use the points A and B ′:

m' = (2b - b)/[a  - (-b/m +a)]

m' = b/(b/m)

m'  =m

And,

y−yA' = m' (x−xA')

y−2b=m(x−a)

y=mx−am+2b

The translation of the line's x and y intercepts are:

Put x=0

⇒y = m⋅0−am+2b

⇒y = 2b−am

And, put y=0

⇒0 = mx−am+2b

⇒x = a - (2b/m)

Therefore, the equation of the translate line is found to be  y = mx − am + 2b.

And, the value of the y-intercept is found to be 2b−am.
