can someone help me really please​

Answer:

just randomly write a¹⁰

Step-by-step explanation:

lets say the first is x and the second is y then we can say

x+y=55 ......1

x-y= -1 .......2

by adding 1 with 2 then

x+y+x-y=55+(-1)

==> 2x= 55-1=54

==> x= 54/2=28

if we put x=28 in the 2nd equation then

28-y= -1

==> y=29

Answer:

  $2,856.80

Step-by-step explanation:

The formula for the balance of an account earning interest compounded annually is ...

  A = P(1 +r)^t . . . . where P is the principal invested at annual rate r for t years

__

Using the given values, we find the account balance to be ...

  A = $8400(1 +0.05)^6 ≈ $11,256.80

The excess over the initial investment is the interest earned:

  $11,256.80 -8,400 = $2,856.80

The account has accrued $2,856.80 in interest after 6 years.

_____

Additional comment

If the account earns simple interest, it is computed using ...

  I = Prt = $8400(0.05)(6) = $2,520

Answer:

  -1 ≤ x ≤ 2

Step-by-step explanation:

The given equation can be rewritten as a piecewise function and solved in pieces.

The term |x+1| changes definition at x=-1. For x-values less than that, it is defined as -(x+1). Similarly, the term |x-2| changes definition at x=2. For x-values less than that, its definition is -(x-2). In the following, we consider the three pieces of the function.

__

In this domain, the absolute value functions both have negative arguments, so the equation is effectively ...

  -(x +1) -(x -2) = 3

  -2x +1 = 3 . . . . . . . simplify

  -2x = 2 . . . . . . subtract 1

  x = -1 . . . . divide by -2

This value of x is not in the domain we have defined, so there is no solution in this domain.

__

In this domain, the function |x+1| has a non-negative argument, but the function |x-2| has a non-positive argument. The equation is effectively ...

  (x +1) -(x -2) = 3

  x -x +1 +2 = 3 . . . . . eliminate parentheses, group like terms

  3 = 3 . . . . . . . . . true for the entire domain

The solution here is -1 ≤ x ≤ 2.

__

Both absolute value terms have positive arguments in this domain, so the equation is effectlvely ...

  (x +1) +(x -2) = 3

  2x -1 = 3 . . . . . simplify

  2x = 4 . . . .  add 1

  x = 2 . . . . divide by 2

This value of x is not in the domain we have defined, so there is no solution in this domain.

__

The solution to the given equation is -1 ≤ x ≤ 2.

Answer:

u should've cropped out ur name

Step-by-step explanation:

The equation that defines 'x' as a function of 'y' will be x = 5 - 3y. Then the correct option is A.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

Let's check all the options, then we have

A. x = 5 - 3y, the independent variable is 'y' and the dependent variable is 'x'.

B. y = 0x + 5, the independent variable is 'x' and the dependent variable is 'y'.

C. x² + y² = 2, it is not a function because the number of values of 'x' and 'y' will be two.

D. x² = y, it is not a function because the number of values of 'x' will be two.

The equation that defines 'x' as a function of 'y' will be x = 5 - 3y. Then the correct option is A.

Answer:

x=0 and y=4 thats where the points meet

Step-by-step explanation:

solution of x and y:

both equations equal to y so you can put them together

3/5x+4=-x+4

separate the variables and numbers...

1.6x=0

x=0

y=4

if ur using a graph, use the y intercept (0,4) for your first point

then, using y=-x+4, make -x a fraction -1/1

by using rise/run go down one unit from (0,4) since its negative 1

then one unit to the right from where you are

you should be able to connect the points for the first equation

find the second equation on your own now:)

Answer:

This is what it should look like. The slope is 0 and there are two points. (0,3) (1,3)

The distance between you and your friend rounded  to the nearest tenth is 10.7 feet.

The distance between you and your friend can be found using cosine rule.

Therefore,

c²  =a² + b² - 2ab cos C

Therefore,

let

x = distance between him and his friend

x² = 7² + 6² - 2 × 7 × 6 cos 110°

x² = 49 + 36 - 84 × -0.34202014332

x² = 49 + 36 + 28.7296920394

x² = 113.729692039

x = √113.729692039

x = 10.6644124076

Answer:

Step-by-step explanation:

The given relationships can be translated to equations using L and W for the length and width of the rectangle. The distance from the center to the short side is L/2, and the distance from the center to the long side is W/2.

  P = 2(L +W) . . . . . formula for the perimeter

  56 = 2(L +W) . . . . . the perimeter is 56 cm

  L/2 = 4 + W/2 . . . . . distance to short side is 4 cm longer

__

Dividing the first equation by 2 gives ...

  28 = L +W

Multiplying the second equation by 2 gives ...

  L = 8 + W

Substituting for L in the first equation, we have ...

  28 = (8 +W) +W . . . . . . use L=8+W

  20 = 2W . . . . . . . . .subtract 8

  10 = W . . . . . . . . divide by 2

  L = 8 +10 = 18 . . . . . find the length

Answer:

(0,-2)

Step-by-step explanation:

one way to solve...

3x - y = 2 --> *4

-2x + 4y = -8

multiply the first equation by 4

12x - 4y = 8

-2x + 4y = -8

-----------------

10x = 0

x = 0

y = -2

this method is called elimination

another way to solve...

3x - y = 2 simplify for y to get y = 3x - 2

-2x + 4y = -8 substitute y into this equation to solve for x

-2x + 4(3x - 2) = -8

-2x + 12x - 8 = -8

10x = 0

x = 0

y = -2
