Y=-4x-10
2x+5y=-14

2x+5(-4x-10)=-14
2x-20x-50=-14
-18x=36
x= -4

y=-4(-4)-10
y=16-10
y=6

Two angles are said to be complementary, if the sum of the measures of the to angles is equal to 90 degrees.

Thus, given that HFG is complementary to ACB, them mHFG + mACB = 90 degrees.

From the figure, given that the line from point F meats line CE at point P, then HFG = CFP.
But mCFE = 90 degrees and mCFE = mCFP + mPFE
Also PFE = DFH

Thus, mCFE = mCFP + mPFE = mHFG + mDFH = 90 degrees

Recall that mHFG + mACB = 90 degrees

Thus, mHFG + mACB = mHFG + mDFH

Therefore, mACB = mDFH.

Answer:

x < -14

Step-by-step explanation:

Step 1: Subtract 6 from both sides.

  • -3x+6-6 > 48-6
  • -3x > 42

Step 2: Divide both sides by -3 and flip the inequality sign.

  • -3x/-3 > 42/-3
  • x < -14

Therefore, the answer is  x < -14.
