Using a calculator, we see that
-1/2 = -0.5
-1/3 = -0.333 approximately
So saying "some number between -1/2 and -1/3" is roughly the same as saying "some number between "-0.5 and -0.333". Choice A can be ruled out because -0.53 is not between -0.5 and -0.333. Choice B can be eliminated for similar reasons. The same story happens with choice D as well.
The only possible answer is choice C. The values -0.4 and -0.454545... are between -0.5 and -0.333... so that helps confirm the answer
Let the numbers be n, n+2, n+4
Sum equals too= 13+2(n+4), which is 2n+21
a) Equation--> n+n+2+n+4= 2n+21
b) Solution--> 3n+6= 2n+21
=> n= 15
c) Second number--> 17 (15+2)
Third number--> 19 (15+4)
d) 15+15+2+15+4=30+21
=> 51= 51
So, the equation is true.
And pls mark me brainliesttt :)))

Answer:
y = -2·(1/2)^x
Step-by-step explanation:
The general form of the equation can be written as ...
y = a·b^x
where 'a' is the value of the y-intercept, and 'b' is the ratio of y-values for x-values that differ by 1.
From your table and graph, a = -2. From the table, ...
b = -1/-2 = 1/2
Then the exponential equation is ...
y = -2·(1/2)^x
