Answer:
11
Step-by-step explanation:
3+(−3)^2−(9+7)^0
=3+9−(9+7)^0
=12−(9+7)^0
=12−16^0
=12−1
=11
any number to the power of 0 is ALWAYS 1
Answers
(1) a = 16 , (2) x =4 , (3) x = 0 ,(4) n =-20 , (5) r = 20 and (6) x = -11
Step-by-step explanation:
(1) 6 = a/4 + 2
4 = a/4 (It is because when you bring +2 over to the left it will become 6 -2)
a = 16 (it is because of the fraction, so when you bring the divisor over it becomes x 4)
The following questions same as qns 1 too
(2) -6 + x/4 = -5
x/4 = 1
x = 4
(3) 9x -7 = -7
9x = 0
x = 0
(4) 0 = 4 + n/5
-4 = n/5
n = -20
(5) -4 = r/20 -5
1 = r/20
20 = r
(6) -1 = 5 + x/6
-6 = 5 + x
-11 = x
Answer:
.
Step-by-step explanation:
The equation is
y = 200+50x
This is not a proportional relationship because it does not go through the origin
If x=0, y does not equal 0
Answer:

Answer:
4y is not a like term.
Step-by-step explanation:
Unlike the other variables, 4y has a y instead of an x. The numbers with an x variable can all be combined, but 4y can't be combined with an x variable.
