Both define y, so they are equivalent.
5x-9=2x+6
3x-9=6
3x=15
x=5
Then plug in x into any of the equations
y=2(5)+6
y=10+6
y=16
Final answer: (5,16)
Answer:
I'll just do the entire thing since it's 13 points
<em>1.</em> 35
<em>2. </em>45
<em>3. </em>45
<em>4. </em>65
<em>5. </em>115
<em>6. </em>65
<em>7. </em>80
<em>8. </em>35
<em>9. </em>145
Answer:
75 degrees
Step-by-step explanation: the 15 degree angle is adjacent to angle fgd so its 15 and then all of the other angles add up to 90 degrees then you subtract 15 from 90 and get 75. Im not very good at explaining it don't know if im using the right terms but I know how to do it for sure.
