Answer:
y = 18·8^x
Step-by-step explanation:
We assume you want a model that looks like y = ab^x.
To find the values of "a" and "b", you can fill in the given numbers and solve the system of equations:
18 = a·b^0
9216 = a·b^3
The first equation tells you ...
18 = a
Dividing the second equation by the first gives ...
9216/18 = (a·b^3)/(a·b^0) = b^3
512^(1/3) = b = 8
The exponential function is ...
y = 18·8^x

Answer:
x=8/3 OR 2.7
Step-by-step explanation:
-1.3+4.6x=0.3+4x
4.6x-4x=0.3+1.3
0.6x=1.6
x=1.6/0.6=8/3
x=8/3 OR 2.7

Answer:
(a) draw the graph using these coordinates :
(0,-1) and (3,1)
(b) x = 3
Answer:
The coefficient is 3 and the constant is 4 in
relation to the equation mx + c where m is the coefficient of x and c is the constant.
6x-2=5x+29
6x-5x-2=29
x-2=29
x=31
(-1, 0)
As you can see, they're clearly intersecting at that point, which means that the solution is that point.
