Answer:
Decreased by 20%.
16 lbs is 80% of 20 lbs.
Step-by-step explanation:

y × 20 = 16 × 100
20y = 1600
20y ÷ 20 = 1600 ÷ 20
y = 80
100% - 80% = 20%
I prefer to use compatible numbers because by using this method it is easier to make a sum mentally. This is true because compatible numbers are close in value to the actual numbers. For a better understanding, let's take an example:
Suppose you have two numbers, namely 640 and 40. These two numbers are compatible for division because:
64 ÷ 4 = 16
So, we have used mental arithmetic to solve a more complex problem.
Answer:
The range of the function will be (- ∞, 4].
Step-by-step explanation:
See the graph attached.
Here we have to get the range of the graphed function.
The value of y in the graphed function varies in the range of less than or equal to 4.
Because the graph of the function does not move beyond 4 towards +∞.
Therefore, the range of the function will be (- ∞, 4]. (Answer)
Answer:
she needs to subtract 5-3 first
Step-by-step explanation:
Answer:
(6, -9)
Step-by-step explanation:
The transformation from point (-3, -3) to point (4, -5) is the same transformation from point (-1, -7) to the missing point.
Let's find the transformation from point (-3, -3) to point (4, -5).
x: 4 - (-3) = 7
y: -5 - (-3) = -2
Now we apply a transformation of 7 in x and -2 in y to (-1, -7).
(-1 + 7, -7 + (-2)) = (6, -9)
Answer: (6, -9)
