Hello i need help with this one its only one.

Step-by-step explanation:

I don't understand. what are W, C, Y, Z ?

all I can do is solving the 4 systems of equations for x and y.

y = -2x - 3

y = 2x - 1

adding the equations

2y = 0 - 4 = -4

y = -2

-2 = 2x - 1

-1 = 2x

x = -1/2

y = x + 4

y = -x + 2

adding the equations

2y = 0 + 6 = 6

y = 3

3 = x + 4

x = -1

y = -2x + 3

y = x + 4

multiply second equation by 2, add the result to first

2y = 2x + 8

3y = 0 + 11 = 11

y = 11/3

11/3 = x + 4 = x + 12/3

x = -1/3

y = 2x - 1

y = -x + 2

multiply second equation by 2, add the result to first

2y = -2x + 4

3y = 0 + 3 = 3

y = 1

1 = -x + 2

-1 = -x

x = 1

x³ + 6x² + 4x + 24

= x² (x + 6) + 4 (x + 6)

= (x² + 4) (x + 6)

Answer:

$720

Step-by-step explanation:

I (Interest) = P (principal) x R (rate) x T (time, in years)

I = 8000 x .03 x 3

I = 720

Answer:

[tex]k\le \:-18[/tex]

Step-by-step explanation:

First, you add 66 to both sides so then the equation you are trying to solve will be: [tex]k-66+66\le \:-84+66[/tex]

Finally, you simplify and get: [tex]k\le \:-18[/tex]

Hope this helped!

Answer:

25.92 sorry if i get this wrong!

Step-by-step explanation:

because we are finding for the variable and not the coefficient we divide it by the number attached to the variable which is the coefficient to get the result of the variable

Answer:

t

Step-by-step explanation:

This is cross multipication.  Multiply 117 times 36 together for that you would use a calculator. You get 4221. Next step is to multiply x and 12 together that would be 12x.

4221= 12x

Divide  by 12 on both sides:

x= 351

351 is # of trouts in the lake .

Answer:

  ab/2 +3c

Step-by-step explanation:

Maybe you want to translate this to an algebraic expression.

__

The product of a and b is written ab.

Half that can be 1/2ab or ab/2. The latter tends to be less ambiguous.

Thrice c is 3c.

So, your expression is ...

  ab/2 +3c

4.475 or 4 19/40 gallons

How?

12.65=253/20

253/20= 12 13/20

////////

I need a similar denominator of 12 13/20 and 17 1/8.

12 13/20×2/1= 12 26/40

17 1/8×5= 17 5/40

17 5/40-12 26/40= 4 19/40

Therefore,

the answer is 4 18/40 gals

Answer:

4 19/20                      

Step-by-step explanation:

17 1/8 - 12 13/20 = 4 19/20

Answer:

cost

Step-by-step explanation:

Answer:

$3.30

Step-by-step explanation:

1 kg = 1000 g

therefore, 150 g = 0.15 kg

multiply the cost by the amount

22 x 0.15 = 3.3, or $3.30

The value of x from the system of equation is 0

Given the systems of equation

–3x + 8y = 16

3x + 4y = 8

Using the elimination method.

Add both equations

-3x + 3x + 8y + 4y = 16 + 8

12y = 24

y = 24/12

y = 2

Substitute y = 2 into equation 2:

3x + 4y = 8

3x + 4(2) = 8

3x = 8 - 8

3x = 0

x = 0

Hence the value of x from the system of equation is 0.

Step-by-step explanation:

[tex] {5}^{2} + {2}^{2} = 25 + 4 = 29 \\ \\ {6}^{2} + {1}^{2} = 36 + 1 = 37[/tex]

The values are 29 = 5² + 2² and 37 = 6² + 1².

The definition of a square number states that they are numbers that have been multiplied by themselves. In other terms, a natural number is referred to as a square number if it is multiplied by itself.

Decimal squares are fairly simple to calculate, and the process is the same for both whole numbers (integers) and decimals.

Given numbers 29 and 37

to express in form of sum of two square

let = 29 = a² + b²

the perfect square number near 29 is 25

29 = 25 + 4

29 = 5² + 2²

and 37 = a² + b²

the perfect square near 37 is 36

37 = 36 + 1

37 = 6² + 1²

Hence the numbers in sum of two squares are,

29 = 5² + 2² and 37 = 6² + 1²
