Answer:
If its all together then its 7/8
Answer:
1. f (2) = 3 x 2^x-1
2. f (-1) = -3 x 2^x
3. f (10) = 3 x 2^x/10
Step-by-step explanation:
Answer:
<u>The correct answer is A. 14 x + 6 y = 10. Negative 14 x minus 35 y = 77</u>
Step-by-step explanation:
Let's find out the constants to eliminate the x terms
7 x + 3 y = 5
2 x + 5 y = negative 11
Let's multiply the first equation by 2 and the second one by -7, this way:
2 * (7 x + 3 y = 5)
-7 * (2 x + 5 y = negative 11)
14x + 6y = 10
-14x - 35y = 77
<u>The correct answer is A. 14 x + 6 y = 10. Negative 14 x minus 35 y = 77</u>
We know that
[volume of a cube]=b³---------> b=∛Volume
b------> is the side length of a cube
The top block was 64 cm³------> b1=∛64-------> b1=4 cm
The middle block was 125 cm³------> b2=∛125------> b2=<span>5 cm
T</span>he biggest block was 729 cm³------> b3=√729------> b3=<span>9 cm
[</span><span>the stack of blocks tall]=b1+b2+b3-------> 4+5+9-----> 18 cm
</span><span>
the answer is
</span>the stack of blocks was 18 cm tall<span>
</span>
