Answer:
D
Step-by-step explanation:
Exponential equation takes the form
where
- a is the initial value ( a ≠ 0), and
- b is the base ( b ≠ 1)
The equation given in the problem can be written as
, so it is <em>an exponential equation, </em> where a = -4.8 and b = 4.
Thus we can say that the initial value = -4.8 and the base is 4
The correct answer is D
y = mx + b, where m = slope, and b = y-intercept.
Since you are not given the y-intercept, you have to solve for it through the equation, y = (4/5)x (which is the slope you are given) + b, and replace x and y with values given, which are (-5,-3)
y = (4/5)x + b
-3 = (4/5)(-5) + b
-3 = -4 + b
1 = b
Then replace b in the first equation to get the answer
y = (4/5)x + 1
<span>(1/6)*s-((1/2)*(s-2)) = 45/2 // - 45/2
(1/6)*s-((1/2)*(s-2))-(45/2) = 0
(-1/2)*(s-2)+(1/6)*s-45/2 = 0
s/6-1/2*(s-2)-45/2 = 0
(-1/2*2*6*(s-2))/(2*6)+(2*s)/(2*6)+(-45*6)/(2*6) = 0
2*s-1/2*2*6*(s-2)-45*6 = 0
12-4*s-270 = 0
-4*s-258 = 0
(-4*s-258)/(2*6) = 0
(-4*s-258)/(2*6) = 0 // * 2*6
-4*s-258 = 0
-4*s-258 = 0 // + 258
-4*s = 258 // : -4
s = 258/(-4)
s = -129/2
s = -129/2</span>
