Substitution because you need to substitute one of the variables
Answer:
27
Step-by-step explanation:
If k/3 = 9
K must be 27
because 9*3=27
and to check we can do
27/3
and 27/3 = 7
x=5 5=x should be reflexive property
Answer: the slope is 5/3
Step-by-step explanation:
The slope intercept form represents the equation of a straight line. It is expressed as
y = mx + c
Where
m = slope
c = intercept
The given equation is 5x - 3y = 2
Rearranging it so that it will conform to the slope intercept form of equation, it becomes
3y = 5x - 2
y = 5x/3 - 2/3
Comparing with the slope intercept equation,
Slope, m = 5/3
If two lines are parallel, it means that they have the same slope. It means that the slope of the line parallel to the given line is 5/3
For number two, answer is: r=2
A= π•r^2
C=2 πr
2r=r^2
If r=2 then,
2•2=2^2
4=4
Answer for number three is: A=5981m^2
Explanation for number 3 in photo below.
Good luck.
