Step-by-step explanation:
To begin the problem asks to find 
· 
which can be defined as ](https://tex.z-dn.net/?f=%5Bf%2Ag%5D%28x%29)
. Now we are given that:
So now we need to 'multiply' our two algebraic expressions as follow:
Eqn.(1)
The domain of Eqn. (1) is all real numbers of 
.
Which according to the given options , Option 3 is correct.
Jenny: x
Thomas: 3x
Ali: x-5
Jenny: 12
Thomas: 3 x 12= 36
Ali: 7
Thomas is 24 years older than Jenny
Answer:
C
Step-by-step explanation:
Simply by substitution, you can figure out which function is shown on the graph.
-If the exponent x were zero, the number to the power x would be 1, because any number to the power of zero is 1. Therefore, the number in the front that is not being raised to the power of x, would be the y intercept, when the value of x is 0.
-Because B and D do not have 4 being multiplied to the number being raised to the x power, we can eliminate those.
-Then simply plug in the values of (1,8) into the functions.
A. f(x)=4*(8)^x
y=4*(8)^1
8=4*(8)^1
8=32
This is not true, so A is eliminated.
C. f(x)=4*(2)^x
y=4*(2)^1
8=4*(2)^1
8=8
This is true, so C is the answer.
Hope this helped you ^^
Answer:
4
Step-by-step explanation:
The triangle are similar which means the ratio between sides is the same.
In this case the sides on triangle DEF are 5 times the length of the sides on triangle ABC. So the ? is 20/5.
20/5 = 4
