Answer:
Step-by-step explanation:
First find the equations of the lines, then fill in the proper inequality sign. The upper line has a y-intercept of 1 and a slope of 1/2, so the equation, in slope-intercept form is

Since the shading is below the line, the inequality sign is less than or equal to. The inequality, then, is

But the solutions are in standard form, so let's do that:

AND they do not like to lead with negatives, apparently, so let's change the signs and the way the inequality is facing, as well:

Let's do the sae with the lower line. The equation, in slope-intercept form is
since the slope is 3/2 and the y-intercept is -3. Now, since the shading is above the line, the inequality is greater than or equal to:

In standard form:
and not leading with a negative gives us

Those 2 solutions are in choice B, I do believe.
A trinomial consists of 3 variables. Hence the answer will be A. C2 + C + 6
Which one you need help on
Answer:
9 Miles to be specific 8.95
Step-by-step explanation:
3 miles = 4.83 km
4.83 km = 4830 m
60 seconds X 45 =2700 Seconds
4830 divided by 2700 = 1.78 m/s
you want to know the distance so its speed X time
135 minutes X 60 seconds = 8100 secs
1.78 m/s X 8100 =14418 meters
14418 = 14.418 km
14.418 km = 9 miles
P.S. There is a shorter version but i think this is simpler for me and I use metric units.
You have a line:
y=mx+b (slope-intercepted form)
m=slope of this line.
The slope of a line perpendicular to that given line will be: ´"m´"
m´=-1/m.
For example:
y=8x+3
m=8
The solpe fo a line perpendicular to "y=8x+3" is:
m`=-1/8
