Answer: The first one is "translated 4 units down". The second one is "vertically stretched by a factor of 4".
Recall that y = f(x). When we say f(x)-4, we really mean y-4 so that means each y coordinate of all the points on the graph have been reduced by 4. Visually this shifts the graph down 4 units. A translation in geometry is the technical term for shifting.
When we say 4*f(x), we are multiplying each y coordinate by 4. A point like (1,2) turns into (1,8) for instance. If you apply this to every point on the graph, then the curve is stretched vertically to be 4 times taller than it usually is; which is an informal way of saying "vertically stretched by a factor of 4"
Answer:
A= 16 B=28
Step-by-step explanation:
So the ration is 4:7, you have to find multiples that have that same ratio
Multiply both numbers by 4, this should get you
16:28
16 + 28 = 44
Therefore this is the correct answer

Answer:
The missing number is 150
Step-by-step explanation:
45 + 5= ? -100
To carry out the problem we are going to call x to (?)
45 + 5= x -100
we see that we have a -100 of the second side of the equality, to get it out of there we can add 100 in both parts of the equality
45 + 5 + 100 = x -100 + 100
now we just solve and we have left
45 + 5 + 100 = x
As we see this is a common sum, by which we can already add it and obtain the value of x
150 = x
Im positive its false because they dont add up
