Step-by-step explanation:
the third of 7 consecutive numbers is 12.
so, this looks like
..., ..., 12, ..., ..., ..., ...
that means the numbers have to be
10, 11, 12, 13, 14, 15, 16
the sum is then
16+10 + 15+11 + 14+12 + 13 = 3×26 + 13 = 91
Answer:
x= 0
y= -3
6x-5y=15
substitution...
6(y+3)-5y=15
6y+18-5y=15
y+18=15
-18 -18
substitution again...
6x-5(-3)=15
6x+15=15
-15 -15
6x=0
/6 /6
yes
for (-3)^4, if there were more numbers in the parentheses, the exponent would apply to all numbers in the parentheses
for -3^4, the exponent would only apply the -3.
hope this helps!
Answer: Constant.
The graph does not have an incline and therefore has a slope of 0. This means that the graph is constant.
