Answer:
x=5
Step-by-step explanation:
Step 1: you want to have x alone on one side so I will subtract one x from both sides (to remove the 1 x on the right side). Now we're left with 3x=15.
Step 2: Divide both sides by 3 (to remove the 3 in front of 3x). Now we have x=5.
Answer:
Step-by-step explanation:
<u>Use intersecting chords theorem:</u>
- 5(5x + 2) = 10(6)
- 5x + 2 = 12
- 5x = 10
- x = 2
X^2+20=4
Subtract 20 from both sides.
x2+20−20=4−20
x2=−16
Take square root.
x=±√−16
Answer
No real solutions.
Answer:
y=2/5x-7
Step-by-step explanation:
2x−5y=35
Step 1: Add -2x to both sides.
2x−5y+−2x=35+−2x
−5y=−2x+35
Step 2: Divide both sides by -5.
-5y/5=-2x+35/-5
y=2/5x-7
