Answer:
1. D
2. A
Step-by-step explanation:
Q1. Kerry is simplifying 
By the definition of negative powers,

Hence,

So, the first step in simplifying the expression is

Q2. Given the expression

First, use the definition of negative powers:

Thus,

It’s just 5 you divide 9 into 45 and get a whole number of 5
Or 1 kilogram<span> = 2 pounds 3 ounces. To change from </span>KILOGRAMS<span> TO POUNDS we can multiply by 2.2. So is we have a 2kg bag of </span>flour<span> and we want to know what this is in pounds we can work it out like this: 2kg = 2 x 2.2lbs = 4.4lbs. A. Try these. </span>1<span>) 3kg = lbs. 2) 6kg = lbs. 3) 7kg = lbs. 4) 12kg = lbs. </span>5<span>) 14kg = lbs. 6(
</span>
Answer:
Adding the exponents
Step-by-step explanation:
Multiplying exponential terms with the same base
To multiply exponents with same base , we use exponential property

When we multiply exponents with same base then we add the exponents
So, adding the exponents best explains to simplify the expression that has same base with exponents .
Here, equation of a line, y + 2 = 1/3 (x -5)
slope = 1/3
Slope of the line which is perpendicular would be -3 [ reciprocal & opposite ]
Now, y - y1 = m(x-x1)
y - 3 = -3(x - (-4))
y - 3 = -3x - 12
y = -3x - 9
In short, Your Answer would be y = -3x - 9
Hope this helps!
