Answer:
No positive value of n
Step-by-step explanation:
we have to find out for how many positive values of n are both
our-digit integers
Let us consider first cube
we get 4digit lowest number is 1000 and it has cube root as 10.
Thus 10 is the least integer which satisfies four digits for cube.
The highest integer is 9999 and it has cube root as 21.54
or 21 the highest integer.
Considering 3^n we get,
3^10 is having 5 digits and also 3^21
Thus there is no positive value of n which satisfy that both n cube and 3 power n are four digits.

Answer:
2x + y = -10
Step-by-step explanation:
Simplify −2(x+7)
y−4=−2x−14
Move all terms containing variables to the left side of the equation.
2x+y−4= −14
Move all terms not containing a variable to the right side of the equation.
2x + y = −10
Hope this helps
15+3x-4+6x= 9x+11 add 6+3 then subtract 15-4
3y-4x+8x-y= 4x+2y add -4+8 then subtract 3-1
5x+8x+10x-3x= 20x Add 10+5+8 to get 23 then subtract 3
Jaun has to use inverse before using those properties as they does not support subtraction but only addition.
<u>Solution:</u>
Given that , Juan used the expression 16 – 9 – 12 + 22 to find his profit for days 2 and 3.
He rewrote the expression as 16 + (–9) + (–12) + 22
Juan can use the associative and commutative properties to rewrite the expression again.
We have to explain why he had to use the additive inverse before he could use these properties.
Now, Associative property and commutative property true for addition.
i) a + (b + c) = (a + b) + c ---> Associative property of addition
ii) a + b = b + a --> commutative property of addition.
These properties not true for subtraction.
That's the reason Juan used additive inverse before applying these property.
Hence, jaun has to use inverse before using those properties as they does not support subtraction but only addition.
