Answer:
124.5
Step-by-step explanation:
All you need to do is multiply.
15*8.3=124.5
This is because The total water in Ari's fish tank has 15 gallons, and each gallon has 8.3, so you multiply.
Standard form of an exponential function is y=ab^x
when x=0, y=3, 3=ab^0, so you can figure out that a=3
when x=-1, y=6, 6=3b^(-1), b^(-1)=2, b=1/2
so the equation is y=3(1/2)^x
Answer:
y = 
x + 2
Step-by-step explanation:
Slope-intercept form is y = mx + b with m as the slope and b as the y-intercept.
The y-intercept is the point where the line intersects the y- axis.
y = mx + 2
The equation to find slope is 
Two points from the line: (0,2) (4,8)
= 
=
y = x + 2
