Find the value of x that makes line m ll n
guapka [62]

Answer:

See below ↓

Step-by-step explanation:

14.

  • Between two lines m ║ n, the ∦ cuts through them forming two angles
  • As it forms a line, the sum of the angles is 180°
  • 3x + 47 + x + 7 = 180
  • 4x + 54 = 180
  • 4x = 126
  • x = 126/4 = 63/2 = 31.5

15.

  • Alternate exterior angles on a transversal are equal
  • 5x = 2x + 78
  • 3x = 78
  • x = 26

Given f(x)=2x^2+9x+k, and the remainder when f(x) is divided x+7 is 32, then what is the value of k?
sweet-ann [11.9K]

Set up either long division or synthetic div.  I'd do the latter.

Your divisor for synth. div. should be -7.

                           __________  
Then              -7 /  2      9      k
                                    -14   +35
                          --------------------
                             2      -5      k+35                 Rem is 32; 
                                                                     Let 32 = k + 5 and solve for k:

                                                                           k = -3.

Let's check that.  Is k correct?

Then              -7 /  2      9      -3
                                    -14   +35
                          --------------------
                             2      -5      -3+35  = 32

Since the rem is 32, we are correct; k = -3.
