You are given the following system.x=2y+42x-3y=11 What method would you use to solve this system?
qwelly [4]

Answer:

substitution

Step-by-step explanation:

We assume the two equations are ...

  • x = 2y+4
  • 2x -3y = 11

You are given an expression for x. Using that in the second equation will result in an immediate solution for y.

... 2(2y+4) -3y = 11 . . . . . substituting 2y+4 for x

.. y +8 = 11

... y = 3

... x = 2·3 +4 = 10

The solution is (x, y) = (10, 3)

Solve the inequality.<br><br> 9(2 − x) − 4(2 − 3x) &gt; 9
e-lub [12.9K]

Remove both sets of brackets.

18 - 9x - 8 + 12x > 9 Collect like terms on the left.

12x - 9x + 18 - 8 > 9

3x + 10 > 9 Subtract 10 from both sides.

3x > 9 - 10

3x > - 1 divide by 3

x > -1/3

Notice what the graph is telling you. A blue dotted line is going through x = - 1/3 or - 0.3333

Everything to the right of - 0.333 is colored blue and that means anything to the right if going to be a solution to the inequality. To confirm this for yourself, try zero and 1. Both should give larger than 9 solutions.

Kelly makes 4 candles per hour (12/3=4). Lee makes 6 candles per hour (6/1=1). In 8 hours, Kelly makes 32 candles (4*8=32). In 8 hours, Lee makes 48 candles (6*8=48). The difference in the numbers of candles is 16 (48-32=16).
