İn the system equations above, n is a constant. İf the system has no solution, what is the value of n
jarptica [38.1K]

Answer:

  • n = - 6

Step-by-step explanation:

<u>Given is the system of linear equations:</u>

  • nx + 3y = 6
  • 12x - 6y = 0

<u>Convert both equations into slope intercept form:</u>

  • nx + 3y = 6 ⇒ 3y = - nx + 6 ⇒ y = - 1/3nx + 2
  • 12x - 6y = 0 ⇒ 6y = 12x ⇒ y = 2x

<u>The system has no solution if lines have equal slopes with different y-intercepts:</u>

  • -1/3n = 2
  • n = - 6

Solve for<br> 8 - 6r + 3 = 5
Oksanka [162]

Answer:

r = 1

Step-by-step explanation:

8 - 6r + 3 = 5

Combine like terms

11 - 6r = 5

Subtract 5 from both sides

6 - 6r = 0

Add 6r to both sides

6 = 6r

Divide both sides by 6

1 = r

Tim and Tom are painters. Tim and Tom use a liters of paint on a large shipping crate. If the next crate they need to paint is s
antiseptic1488 [7]
This is the concept algebra.
Volume of of paint that is required to paint  large shipping crate is a liters.
suppose the volume of this crate is x cubic units.
The volume of the next crate to be painted will be 2x cubic units.
Hence the amount of paint required to paint the crate will be:
(volume of bigger crate)/(volume of smaller crate)×(volume of liters required to paint the first crate)
=(2x)/(x)×a
=2a liters
To paint the new crate 2a liters of oil is needed.

(06.04 MC)
ratelena [41]

Answer:

54 sq units

Step-by-step explanation:

The triangle at the top (FAB) has a base of 10 and a height of 3. Area of triangle is 1/2bh so 1/2(10 * 3) = 1/2 * 30 = 15 sq units

If you cut off the triangle you have a trapezoid, EBCD. A trapezoid is (b1 + b2)/2 * h, so (6 + 7)/2 * 6 = 13/2 * 6 = 6.5 * 6 = 39 sq units

Add them together: 15 + 39 = 54 sq units
