Answer:
Step-by-step explanation:
So the slope of the line is y = -9x + b
We have
y = -9x + b
Add 9x to both sides
y + 9x = -9x + 9x + b
y + 9x = b
switching sides,
b = y + 9x
Plug in the (x, y) values for point (4, 0)
b = 0 + 9(4)
b = 36
So the equation of the line is
All you have to do is find a least common multiple for 6 and 8 in this case it would be 24 because 6's multiples are 6,12,18,24 and 8's multiples are 8,16,24 and many more but these are the lcm so in it would be
morning- 20/24
and
afternoon - 15/24
the answer is the morning
If you know two points on a line you can solve for slope, m (some people say rise over run, or change in y over change in x). In the attached picture, it's the top equation in blue.
Then you can plug that into the point-slope formula (middle equation, in red), which if needed can be algebraically changed to look like the slope-intercept formula (third equation, in yellow).
But to answer your question, use the point-slope formula.
When the expression has only one KIND of a variable, and also only one kind of a lonely number.
A lonely number is a number that has no variable next to it. Their need to be one kind of it.
Example of a simple expression:-
16c + 3
Answer:
Solution set = (-5, -2)
Step-by-step explanation:
Given equations;
-7x + 8y = 19 ------------- eq1
7x – 9y=-17 --------------- eq2
Adding both equations:
-y = 2
OR
y = 2
Put value of y in eq2:
7x - 9(-2) = -17
7x + 18 = -17
7x = -17 -18
7x = -35
x = -5
Solution set = (-5, -2)
i hope it will help you!
