Answer:
The solution is 1.
Step-by-step explanation:
Logarithm:
Suppose we have a logarithmic equation in the following format:
It means that:
In this question:
Which means that:
Every number, elevated to 0, is 1. So
Which means that the solution is
D) -14x-13
-9x -3 - (5x+3) -7
-9x -3 -5x-3-7
-14x-13

Equation is | x-20 | = 2
Min = 18
Max = 22
==================================================
Explanation:
x = number of strawberries
|x-20| = distance from x to 20 on the number line.
Absolute value is used to ensure the distance is never negative. This distance represents how far off from 20 we are.
For instance, let's say the package had x = 17 strawberries
|x-20| = |17-20| = |-3| = 3
We're 3 units away from the goal of 20
--------------------
Setting |x-20| equal to the error of 2 will help us find the min and max
|x-20| = 2
x-20 = 2 or x-20 = -2
x = 2+20 or x = -2+20
x = 22 or x = 19
The smallest amount is 19 strawberries, while the most is 22. This represents the min and max respectively.
-8x + 16
This is called expanding brackets in algebra
1. you need to multiply the numeral on outside of the brackets with each of thosse on the inside
-4 x 2x = 8x
-4 x -4 = 16
1. 3, 12, 48, 192, 768 Ratio: x4
2. 8, 16, 32, 64, 128 Ratio: x2
3. 120, 60, 30, 15, 7.5 Ratio: ÷2
4. 5, 10, 20, 40, 80, 160 Ratio: x2
5. 1.3?, 4, 12, 36, 108, 324 Ratio: x3
Hope this helps!
I'm not sure about the first one on question 5 though.
