Answer:
Step-by-step explanation:
-intercept(s): (
0
,
8
)
y=8
Because this equation is in slope-intercept form, we can tell exactly how it will look by checking out 3 key points.
Leading coefficient: negative, or positive.
In this case, the leading coefficient is positive, which means that the slope will be going from bottom left to upper right.
Leading coefficient = slope
In this case, the slope is 4, or 4/1, so it will be at a steep incline.
Value of constant = y-intercept.
In this case, the y-intercept is -2, which will help us narrow down our choice.
<h3><u>After reviewing the three answer choices, the most likely selection will be A, as it seems to have a slope of 4, it is positive, and it has a y-intercept of -2.</u></h3>
Answer:
Step-by-step explanation:
we know that
The algebraic expression is equal to
Remember that
and
so
substitute
Answer:
8 hours
Step-by-step explanation:
Let t hours be the time needed Sonya to catch up Brianna.
Sonya:
Time = t hours
Rate = 44.8 mph
Distance 
miles
Brianna
Time 
hours
Rate = 32 mph
Distance 
miles
Note that 
because Sonya must catch up Brianna.
Use formula 
Hence,
Solve this equation:
