Answer: 720
Step-by-step explanation: took the test
Answer:
2.
3.
Step-by-step explanation:
We add like terms together to simplify
2. 3x²-4x²= -x² -2x+5x= 3x 6+9= 15 all equal to -x²+3x+15
3. 2x²-3x²= -x² 6x-7x= -x 8+1=9 all equal to -x²-x+9
y=10+x(0.5)
This is the way of writing that equation.
1845-1846
118->148
148-118 = 30 = change
percent
30/118 ≈ 25.4%
1846-1847
148->139
148-139 = 9 = change
9/148 ≈ 6%
1847-1848
139->151
151-139 = 12 = change
12/139 ≈ 8.6%
Hope this helped :)
