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,
Answer:
C. 1/8
Step-by-step explanation:
This is because the number two goes into sixteen eight times. This is the simplest form of the fraction.
Answer:
y = 2/3x + 4
Step-by-step explanation:
y = mx + b
m= 4/6 (y intercept over x intercept)
simplify
m= 2/3
b= 4 (y intercept)
I believe it is b! Have a nice day
Option A - (0,0) is a solution to both the equations. is the only true statement.
Step-by-step explanation:
Step 1 :
Given 2 equations are
n = m
n = 4m
Step 2:
(0,0) is a solution to both the equations.
This statement is true as substituting the point , the equations are true.
Step 3 :
Every solution to n=m is also a solution to n=4 m
Take the point (5,5)
This point lies on the equation n = m, as both the x and y co ordinates are same
n = 4 m = 4 × 5 = 20
So here for n = 5, n = 4 m is not true and hence this point is not a solution for the second equation thought it is a solution for the first equation
Hence this statement is not true
Step 4:
The graph of the solutions is parallel lines
this statement is not true because the 2 lines intersect at (0,0) as observed from step 2.
Step 5 :
No point on the line n=m is also a point on n=4 m
This statement is not true because (0,0) is a point on both the lines.
Step 6 :
Answer :
Option A - (0,0) is a solution to both the equations. is the only true statement.
