Answer:
Look below
Step-by-step explanation:
1) x = 14, because 14 * 14 = 196
2) x = 3 / 16, because ( 3 / 16 ) * ( 3 / 16 ) = 9 / 256
3) x = 8, because 8 * 8 * 8 = 512
4) x = 4 / 7, because ( 4 / 7 ) * ( 4 / 7 ) * ( 4 / 7 ) = 64 / 343
Answer:
... There isnt answer choices...
Answer:
yes
Step-by-step explanation:
x+1 and y+1 it is consistent the equation looks like 1(x)+ 8
Whats the question about????????
<span>4x + 3y = 16
7x + 6y = 31
Note what happens if we mult. the first eqn. by -2:
-8x - 6y = -32
Combining this with the 2nd equation eliminates the variable y:
</span>-8x - 6y = -32<span>
7x + 6y = 31
--------------------
-x = -1, or x = 1. Sub 1 for x in either of the 2 given eqns to find y:
For example: 4(1) + 3y = 16, so 36 = 12, and y = 3. Sol'n is (1,3).</span>
