Answer:
k=−5
Step-by-step explanation:
−3(k+7)−5k+4=23
(−3)(k)+(−3)(7)+−5k+4=23(Distribute)
−3k+−21+−5k+4=23
(−3k+−5k)+(−21+4)=23(Combine Like Terms)
−8k+−17=23
−8k−17=23
Step 2: Add 17 to both sides.
−8k−17+17=23+17
−8k=40
Step 3: Divide both sides by -8.
−8k
−8
=
40
−8
k=−5
Answer:
k=−5
Answer:
X = 20
Step-by-step explanation:
The two angles are vertical.

Answer:
Slope m=2, y-intercept b=5 --> y=2x+5
Slope m=3, y-intercept b=5 --> y=3x+5
Slope m=5, y-intercept b=4 --> y=5x+4
Step-by-step explanation:
The slope number goes with x, and the y-intercept gets either added or subtracted from the end of the equation depending on weather it's positive or negative. (subtracted if it's negative and added if it's positive)
