X + 9y = 8 x − 4y = –18
loris [4]

Step-by-step explanation:

x + 9y =  - 18 \\ 8x - 4y =  - 18 \\ x =  - 18 - 9y \\ 8( - 18 - 9y) - 4y =  - 18 \\  - 144 - 72y - 4y =  - 18 \\  - 76y = 126 \\ y =  - 1.66 \\

x =  - 18 - 9y \\ x =  - 18 - 9( - 1.66) \\ x =  - 18 + 14.94 \\ x =  - 3.06

True or false? The quadratic equation 10p2 - 5p = -8 has one solution.
pav-90 [236]

Answer: False

=============================================

Explanation:

I'll use x in place of p.

The original equation 10x^2-5x = -8 becomes 10x^2-5x+8 = 0 after moving everything to one side.

Compare this to ax^2+bx+c = 0

We have

  • a = 10
  • b = -5
  • c = 8

Plug those three values into the discriminant formula below

d = b^2 - 4ac

d = (-5)^2 - 4(10)(8)

d = 25 - 40*8

d = 25 - 320

d = -295

The discriminant is negative, which means we have no real solutions. If your teacher has covered complex or imaginary numbers, then you would say that the quadratic has 2 complex roots. If your teacher hasn't covered this topic yet, then you'd simply say "no real solutions".

Either way, this quadratic doesn't have exactly one solution. That only occurs when d = 0. Therefore, the original statement is false.

Cross product property
Klio2033 [76]

Using the cross product property on this proportion gives us the following equation:

20 (2x - 9) = 10 (9)

Use the distributive property and multiply

40x - 180 = 90

Add 180 to both sides

40x = 270

Divide 40 from both sides

x = 270/40

Simplify fraction

x = 27/4

This should be your answer. Let me know if you need any clarifications, thanks!

How can you use the DISTRIBUTIVE PROPERTY solve the equation: 3(x-4) = 24 ? *
guapka [62]

By using the Distributive Property, you would multiply 3 into the parenthesis (3 · x and 3 · -4)

3(x - 4) = 24

3x - 12 = 24

Then, you would solve like any normal one-step equation.

3x - 12 = 24

     +12   +12

__________

3x      36

__  =  __

3        3

x = 12, which is your final solution.

If you need any further explanations, please ask me :)
