I'm pretty sure the answer is the top right one because it looks really messed up. i mean, mi/hr*min doesn't equal mi, but im not too sure about the conversion part.
These are in y=mx+b form where m=slope
sometimes b=0
vertical intercept means the y-intercept and the horizonatl intercept is the x intercept so the x intercept is when y=0 and the y intercept is when x=0 so the first one is
y=5x-15
slope=5
y-intercept=-15
x-intercept=3
y=7-x
this can be written as
y=-1x+7
slope=-1
y-intercept=7
x-intercept=7
4x=2y=12
we must get it into slope intercept form
divide the whole thing by 2x=y=12
we can disregard the 12 and get
2x=y or y=2x+0
slope=2
y-intercept=0
x-intercept=0
Answer:
I change the symbol in the final result
X>-7
Because when you divide by negative you should be change it to > ( from < to > ).
All you do is multiply across. For example...
1/3 x 2/5
Multiply the numerators and denominators.
(1 x 2) / (3 x 5)
= 2/15
If you need to, you can simplify but in this case you don't have to.
I hope this helps love! :)
Answer:
c=11d+1
Step-by-step explanation:
First, you should know how will 1 lesson cost. Eventually, 1 lesson costs $11.
c is for the cost.
11 is for the cost of 1 lesson.
d is for the lessons
1 represents (1 lesson, which costs $11)
