Answer:
x = 4/9
Step-by-step explanation:
7(6x + 1) = 3(9 - x)
First, distribute the 7 and the 3 across the parentheses.
42x + 7 = 27 - 3x
Now, combine the variables. (Add 3x)
45x + 7 = 27
Now, combine the constants. (Subtract 7)
45x = 20
Now, isolate the x. (Divide by 45)
x = 20/45
Simplify.
x = 4/9
Answer:
The general form of an exponential function is
.... (1)
Where, a is initial value and b is growth or decay factor.
If b>1, then it is an increasing function and if 0<b<1, then it is a decreasing function.
The given function is
.... (2)
From (1) and (2) it is clear that
The value of a is 6. It means the initial value or y-intercept of the function is 6.
The value of b is 0.4, which is less than 1. It means the function is a decreasing function.
No, Rays go one way only since a point block te other way. Otherwise it wont be a ray :)
