-7 > = 13 - 5x
-7 - 13 > = -5x
- 20 > = -5x....divide both sides by -5, changing the inequality sign
-20/-5 < = x
4 < = x......or x > = 4 <=== its C
I believe you go on the x-axis on -6 and go up to 9. I could never be certain for I just learned this but I believe that is what it is..
Answer:
A) y = 16/(x^2), B) 4/5
Step-by-step explanation:
For A, we can plug in some of the table values to check it. I will try 2 and 3
2. 4 = 16 / (2^2)
16/4 = 4
3. 16/9 = 16 / (3^2)
16/9 = 16/9
B) We can just input y into the formula 25 = 16 / (x^2)
This leaves us with +-4/5

Scientific notation means to write the answer in standard form. standard form helps you to express numbers that are too big or too small to be conveniently written in decimal form.
so for this case, it will be 4.571×10^-4.
when the number is decimal, you move the dot to the right and it will always be multiplying 10 to the power of a negative power.
