Chris is working on math homework. He solves the equation m/6=48 and says that the solution is m=8. Do you agree or disagree wit
vredina [299]

Chris is incorrect. To check the answer, replace m with 8 and simplify the left side. So m/6 turns into 8/6 which converts to the decimal value 1.333 (use a calculator)

Therefore the original equation m/6 = 48 becomes 1.333 = 48 after you plug in m = 8 and simplify fully. The two sides of 1.333 = 48 are not the same, so m = 8 is not the solution.

--------------------

The solution is actually 288 and we can prove it so like this

m/6 = 48

288/6 = 48 .... replace m with 288

48 = 48 .... use a calculator to compute 288/6

So the solution m = 288 is confirmed

------------------

How did I get this answer? By multiplying both sides by 6

m/6 = 48

6*(m/6) = 6*48 ..... multiply both sides by 6

m = 288

So Chris mistakenly divided both sides by 6, which explains how he got 48/6 = 8 as the solution. Instead he should have multiplied both sides by 6. This is to undo the operation "divide by 6" that is being applied to m in the original equation.

Identify the equation in slope intercept from that has a slope of 2 and goes through the point (4, 6).
Mars2501 [29]

Answer:

  y = 2x−2

Step-by-step explanation:

You are given a slope and a point, so you can write the equation using point-slope form:

  y -k = m(x -h) . . . . . . a line with slope m through point (h, k)

Putting in the numbers given, you have ...

  y -6 = 2(x -4)

  y = 2x -8 +6 . . . . eliminate parentheses, add 6

  y = 2x -2 . . . . . . . collect terms.

__

You know that the slope is the coefficient of x, so the first choice is eliminated right away. Trying the point values in the other equations shows you that they only work for the last choice, as shown above.

  • 2·4 +14 = 22 ≠ 6 . . . . second choice doesn't work
  • 2·4 +6 = 14 ≠ 6 . . . . . third choice doesn't work
  • 2·4 -2 = 6 . . . . . . y = 2x-2 is the equation that works
