The answer is B. When you cross multiply it, it doesn't make sense like the rest of them;
A. 1x24= 24
4x6=24
24=24
B. 4x10=40
7x7=49
40 ≠ 49
C. 16x3=48
24x2=48
48=48
D. 36x5=180
10x18=180
180=180
Answer:
g(x) = f(3x) -15
Step-by-step explanation:
Let f(x) be the parent function.
If the function is to be compressed by a factor of 3 horizontally, we must obtain the value f(3) when x=1, for example. We can do that by using 3x as the argument of the function:
g(x) = f(3x)
If its graph is to be shifted downward by 15 units, every value produced by the function must have -15 added to it. That is, the shifted function is ...
g(x) = f(3x) - 15
_____
The attached graph shows an example function compressed horizontally and vertically shifted.

Answer:
Neil is 28yrs and his brother is 42yrs old
Step-by-step explanation:
Let r = Neil's brother's age at birth time
2r = Neil's age now
This means that his brother's current age is 3r
So when Neil = 3r old
His brother = 4r old
3r + 4r = 98
7r = 98
r = 14
So their ages now
Neil's brother = 3*14= 42
Neil = 2*14= 28.
Answer:
R(x) = 2.25x + 4.49
Step-by-step explanation:
Equation form: R(x) = mx + b
m: represents the additional amount Joshua is charged for every day until he returns the movie, which in this case is $2.25. So, the value of m is 2.25.
b: represents the initial cost of renting the movie. Joshua rented the movie for $4.49, so b is 4.49.
Since we know the value of m and b, we can write the equation:
R(x) = 2.25x + 4.49
