Answer:
Step-by-step explanation:The following statements are true about exponential functions:
-The domain is all real numbers.
- The input to an exponential function is the exponent.
- The base represents the multiplicative rate of change.
The reason why the other two options are wrong are explained below:
The range of exponential functions is not always includes negative numbers; on the contrary, the range is the set of all positive real numbers.
The graph of an exponential function does not have a horizontal asymptote at x = 0; contrarily, the equation of the horizontal asymptote of the graph of is y = 0, which is the x-axis.
Answer:
Step-by-step explanation: (Equation 2) = 12(-12+9y/4) - 10y = -8
-144+108y/4 - 10y = -8
-144 + 108y - 40y/4 = -8
-144 + 108y - 40y = -32
108y - 40y = -32+144
68y = 112
Y= 1.64
2-4x+9y=14
12x-10y= -8
2-14+9y = 4x
-12 + 9y = 4x ( equation 3)
(Put in equation 2)
There are 85 seats in each section. 2125 divided by 25 is 85.
C=6x+3(x+1.15)
let x=cost of pen, let c=total cost. Cost of folder is 1.15 more than pen, so cost of folder=x+1.15
A) 4*z = nelya
B) 2 * (z + 20) = nelya + 20
Inputting equation A into B)
2z + 40 = 4z + 20
2z = 20
zoya's age is 10 and nelya's age is 40
