Answer:
b) y = 1/2x+3
Step-by-step explanation:
From looking at the graph alone, we can already remove C and D as an answer because the y-intercept is in then negatives, while those answers say +3, so we can cross those two out.
We can cross A out because that equation has a negative in it, yet the line is current increasing and rising meaning that it is not negative, so we can remove that.
With that, all that remains is B which is our answer.
Answer:
Step-by-step explanation:
i divide all by 4
=-(5z+6)=-5z-6
No it’s a function I think
So, the smaller the exponent the smaller the number. So one that is -9 is very small.
We first want to compare the numbers through the exponents.
-9 is the lowest exponent, meaning it is the smallest number, so any answer that doesn't start with 7×10^-9 is incorrect
Meaning we can cross out answer choices A and B
-7 is the next to smallest exponent, but Choices C and D both have 4×10^-7 as the second, so we cannot out anymore answers.
After that the final two numbers each have the same exponent, so then we look at the actual numbers.
Which are 1 and 2, they are each risen to the 4th power, meaning they have 4 zero's after the number.
So the two numbers we have are 10000 and 20000
10000 is less than 20000, so that means 1×10^4 comes next in our ordering of least to greatest, leaving 2×10^4 as the greatest
So we order them properly from least to greatest, and our chart is:
7×10^-9 < 4×10^-7 < 1×10^4 < 2×10^4
This is the same as answer choice C, so C is your answer! Hopefully this all makes sense!

12 squared + b squared = 13 squared
144+ b squared = 169
b squared = 25
b squared= √25
b=5
