Answer:
1.
2.
3.
Step-by-step explanation:
1.
I like to make it an improper fraction first.
Now take the LCM. The LCM is 20.
Now add them.
Make this into a mixed number.
That's your answer for number 1.
2.
Do the same thing as the previous addition problem but subtract instead.
is your answer for number 2.
3.
is your answer for number 3.
I hope this helps! Let me know if you need help or if I got anything wrong :)
Answer:
y = 1/3x - 2:
y = 12 - 6x:
y = 3x - 7:
Step-by-step explanation:
Hello!
<h3>Slope Intercept Form</h3>The slope-intercept form of a line is
The y-intercept is the "b" value of the line, given as -2.
To find the x-intercept, we simply replace the y-value with 0:
y - intercept: - 2
x - intercept: 6
____________________________________________________
<h3>y = 12 - 6x</h3>
You can rearrange the equation, y = -6x + 12, to find the y-intercept: 12.
Solving for the x-intercept (remember, replace y with 0):
y - intercept: 12
x - intercept: 2
____________________________________________________
<h3></h3><h3>y = 3x - 7</h3>Simply take the "b" value, -7, to find the y-intercept of -7.
Solve for the x-intercept:
y - intercept: -7
x - intercept: 7/3
<u><em>Additional Note:</em></u>
You can also solve for the y-intercept by replacing x with 0. This method can be used for any interests, just plug in the opposite variable from what you are solving for with 0.
The proof is that the x-intercept is the value when the y = 0, the x-axis. You can plug in 0 for y to solve for x. Similarly, when solving for the y-intercept, you plug 0 for x as the y-axis is at x = 0.
