The difference between the square of two numbers is 11. Twice the square of the first number increased by the square of the seco
jeyben [28]

Answer:

Below in bold.

Step-by-step explanation:

x^2 - y^2 = 11

2x^2  + y^2 = 97

From the first equation:

y^2 = x^2 - 11

Substituting in the second equation:

2x^2 + x^2 - 11 = 97

3x^2 = 108

x^2 = 36

x = 6, -6.

Substituting  for x in the first equation:

(6)^2 - y^2 = 11

y^2 = 36 - 11 = 25

y = 5, -5.

|x-5|=3 <br> Whats x? please help?
finlep [7]

Answer:

x = 8 or x = 2

Step-by-step explanation:

We know x - 5 = 3 or x - 5 = -3.

<u>Possibility 1:</u>

Step 1: Add 5 to both sides.

  • x-5+5=3+5
  • x=8

<u>Possibility 2:</u>

Step 1: Add 5 to both sides.

  • x-5+5=-3+5
  • x=2

Step 2: Check if both solutions apply to original equation.

  • |8-5|=3
  • |3|=3
  • 3=3
  • |2-5|=3
  • |-3|=3
  • 3=3

The value of y varies directly with x, and y= -10 when x=40. Identify the value of y when x=-5
scoray [572]

Answer:

y = 1.25

Step-by-step explanation:

Use the direct variation equation y = kx, and solve for k:

y = kx

-10 = k(40)

-0.25 = k

So, the equation is y = -0.25x. Solve for y when x = -5

y = -0.25x

y = -0.25(-5)

y = 1.25

So, y = 1.25 when x = -5
