X^2+43xy+590y^2 resolve into factors

Natalija [7]

Step-by-step explanation:

We have:

x - y = 43 , xy = 15

To find, the value of x^2+y^2x

2

+y

2

= ?

∴ x - y = 43

Squaring both sides, we get

(x - y)^2(x−y)

2

= 43^243

2

⇒ x^2+y^2x

2

+y

2

- 2xy = 1849

Using the algebraic identity,

(a - b)^2(a−b)

2

= a^2+b^2a

2

+b

2

- 2ab

⇒ x^2+y^2x

2

+y

2

= 1849 + 2xy

Put xy = 15, we get

x^2+y^2x

2

+y

2

= 1849 + 2(15)

⇒ x^2+y^2x

2

+y

2

= 1849 + 30

⇒ x^2+y^2x

2

+y

2

= 1879

∴ x^2+y^2x

2

+y

2

= 1879

I will send hint follow this hint then slove it .

A yearbook printer charges based on the number of pages printed. Here is a table that shows the cost of some recent yearbooks:

asambeis [7]

y = 0.012x + 0.65

Number of pages 50.00 100.00 150.00 200.00 
Cost 1.25 1.85 2.45 3.05

x = number of pages
y = cost

intervals of x = 50 pages
intervals of y = 0.60
0.60 / 50 = 0.012

y = 0.012x + 0.65

 x 0.012*x y 
 0.012 50 0.60 0.65 1.25
0.012 100 1.20 0.65 1.85
 0.012 150 1.80 0.65 2.45
 0.012 200 2.40 0.65 3.05

Which set of steps will translate f(x)=6x to g(x)=6x-5-7

Maurinko [17]

THIS IS THE COMPLETE QUESTION BELOW;

Which set of steps will translate f(x) = 6x to g(x) = 6x – 5 – 7?

Shift f(x) = 6x five units to the left and seven units up.

Shift f(x) = 6x five units to the right and seven units down.

Shift f(x) = 6x seven units to the right and five units up.

Shift f(x) = 6x seven units to the left and five units down.

Answer:

Shift f(x)=6x five units to the left and seven units down.

Step-by-step explanation:

We are told to translate the function below

f(x) = 6x to g(x) = 6x – 5 – 7

Which means the process to translate f(x) into g(x) is required.

According to the translation rule

f(x)-------->f(x)+a

If a<0 it shift to downward

If a>0 it shift to upward

Then we have

(X,y) ----->((x - 5, y)

There is a shift by x coordinates towards left by 5 units

then we would have the function as

f'(x) = 6(x-5)

Following the translation rule there is a shift by the function by 7 units downward direction then we have

(x,y) ----->(x,y -7)

Then we have g(x) = 6x – 5 – 7 as our translation product.

Therefore, shift f(x)=6x five units to the left and seven units down.

210 is equal to the total of p and 111

Aleks [24]

Answer:

p + 111 = 210

p = 99

Step-by-step explanation:

Break the question down into parts.

Convert each part into algebraic form (numbers or symbols).

210 => 210

is equal to => =

the total of p and 111 => p + 111

Put the equation together:

210 = p + 111

Usually, the variable is on the left side:

p + 111 = 210

To solve the equation is to isolate "p". This means to keep "p" on the left, and move everything else to the right side. When moving something, do the reverse operation to both sides of the equation.

p + 111 = 210 "111" should be on the left. It's opposite is -111.

p + 111 - 111 = 210 - 111 Simplify. "111" cancels out on the left.

p = 99 Solved for "p"
