7+n/2=10
n/2=10-7
n/2=3
n=2*3
n=6
Answer:
nonlinear
Step-by-step explanation:
It isn't a straight line
Answer:
-5
Step-by-step explanation:
x=? Y=x+3 ; y=-2
replace -2 with Y
-2 = x + 3
Then subtract 3 from both sides
-2 = x + 3
-3 -3
Then the positive and negative 3 cancels out leaving only
-5 = x
Answer:
1
Step-by-step explanation:
The square of the value in the empty space is the constant in the expanded expression. That is ...
[ ]² = 1
The value in the space is ...
[ ] = √1 = 1
The filled-in equation is ...
(3x -1)² = 9x² -6x +1
_____
The expansion of the square of a binomial is ...
(ax -b)² = a²x² -2abx +b²
Above, we used the constant term to find 'b', but we could also have used the linear term:
-6x = -2(3)bx . . . . . a=3 in this problem
1 = b . . . . . . . divide by -6x
Answer:
the answer to the question is 4.4
