Answer:
3rd option: f(x)⇒ +∞ as x⇒-∞ and f(x)⇒ -∞ as x⇒ +∞
Step-by-step explanation:
This is a negative cubic graph, therefore:
Looking at the graph, as x goes towards negative infinity, the y values go toward positive infinity.
On the other hand, as x goes towards positive infinity, the y values go towards negative infinity.
Your answer would be 23.85 but I presume they rounded up so it would be 23.9
The answer would be B because I did this equation on a sheet of paper and I did the parentheses first which led me to my final answer B.
Answer:
For every 1 cup of rice, 2.5 cups of water are required.
Step-by-step explanation:
We can solve this by examining the table closely. We see that the difference of water cups required for 2 and 3 rice cups is 2.5. This stays true for 5 cups of rice. where the difference from the required water for 3 cups of rice is 5.
Simplifying
6y + 1 = 21y + 13
Reorder the terms:
1 + 6y = 21y + 13
<span>Reorder the terms:
1 + 6y = 13 + 21y
</span><span>Solving
1 + 6y = 13 + 21y
</span><span>Solving for variable 'y'.
</span><span>Move all terms containing y to the left, all other terms to the right.
</span><span>Add '-21y' to each side of the equation.
1 + 6y + -21y = 13 + 21y + -21y
</span><span>Combine like terms: 6y + -21y = -15y
1 + -15y = 13 + 21y + -21y
</span><span>Combine like terms: 21y + -21y = 0
1 + -15y = 13 + 0
1 + -15y = 13
</span><span>Add '-1' to each side of the equation.
1 + -1 + -15y = 13 + -1
</span>Combine like terms: 1 + -1 = 0
0 + -15y = 13 + -1
-15y = 13 + -1
Combine like terms: 13 + -1 = 12
-15y = 12
Divide each side by '-15'.
y = -0.8
<span>Simplifying
y = -0.8</span>
