What is the solution to the following system?
hodyreva [135]

Answer:

The correct answer is option 3. (20, 4, 5)

Step-by-step explanation:

To solve this problem we use the substitution method.


3x + 10y -12z = 40 (i)


x-5y = 0 (ii)


x - 4z = 0 (iii)  

We start by clearing x in (iii) and clearing y in (ii).


x = 4z (iii)


y = \frac{1}{5}x (ii)


Now we substitute (iii) in (ii)


y = \frac{4}{5}z (iv)


Now we substitute (iii) and (iv) into (i) and clear z.


12z + \frac{40}{5}z -12z = 40 (v)


8z = 40

z = \frac{40}{8}

z = 5

If z = 5 (v)


We substitute (v) in (iii) and then substitute (v) in (iv)


x = 20\\y = 4\\z = 5

The correct answer is option 3.

Find the solutions of the quadratic equation –9x2 + 49 = 0.
Luba_88 [7]

Answer:

x = 7/3

Step-by-step explanation:

<u>Given equation:</u>

  • –9x² + 49 = 0

To determine the value of "x", we need to isolate the x-variable and it's coefficient on one side of the equation. This can be done by subtracting 49 to both sides of the equation.

  • ⇒ –9x² + 49 - 49 = 0 - 49
  • ⇒ –9x² = -49

We can see that the negative sign in on both sides of the equation. Remove it by dividing -1 to both sides of the equation.

  • ⇒ –9x² = -49
  • ⇒ -9x²/-1 = -49/-1
  • ⇒ 9x² = 49

Clearly, we can see that 9x² and 49 are perfect squares. Therefore,

  • ⇒ 9x² = 49
  • ⇒ (3x)² = (7)²

Take square root both sides of the equation:

  • ⇒ √(3x)² = √(7)²
  • ⇒ 3x = 7

To determine the value of "x", we need to isolate it "completely". This can be done by dividing 3 to both sides of the equation

  • ⇒ 3x/3 = 7/3
  • ⇒ x = 7/3

Therefore, the value of "x" must be 7/3.

Helppppp pls simple algebra hella points show your work
Dmitry_Shevchenko [17]

Answer:

y = -7,   y = -3

Step-by-step explanation:

(y - 3)² = 2y² + 4y + 30

expand:

y² - 6y + 9 = 2y² + 4y + 30

subtract 30 from both sides

y² - 6y + 9 - 30= 2y² + 4y + 30 - 30

simplify:

y² - 6y - 21 = 2y² + 4y

subtract 4y from both sides

y² - 6y - 21 -4y = 2y² + 4y - 4y

simplify:

y² - 10y - 21 = 2y²

subtract 2y² from both sides

y² - 10y - 21 - 2y² = 2y² - 2y²

simplify:

-y² - 10y - 21 = 0

solve y by quadratic equation

         - (-10) ± √ (-10² - 4(-1)(21)

y = --------------------------------------

               2(-1)

y = -7,   y = -3
