Answer:
y ≥ 3x -1; x +3y ≤ 6
Step-by-step explanation:
Both lines are solid, so the only viable choices are those with "or equal to" in the comparison operators: the 2nd and 4th choices.
The line with a slope of +3 is shaded <u><em>above</em></u> the line, so that will correspond to the inequality ...
y ≥ 3x -1 . . . . . . . . . . found only in the 4th choice.
Answer:
Step-by-step explanation:
3x-4y+2=9
-4y= -3x +7
y=3/4 x -7/4
When y=0
0=3/4 x - 7/4
3/4x = 7/4
x=7/3
Therefore solution is (7/3, 0)
Answer:
B) 2.3 miles
Step-by-step explanation:
This is a circle so in geometry we know a bit of formulas for this shape.
In this case we're calculating part of the perimeter of this circle.
From Ranger Station to Petting Zoo.
It tells us that the radius of this circle is 1 mile.
So perimeter of circle is: 6.28
Formula: 2πr
Now we need to find the fraction of the perimeter we're solving for: They state the sector of the circle's degree is 90+40=130 degrees.
So 130 degrees divided by 360 degrees. is 13/36. Now we can multiply 13/36 by 6.28, we get 2.26, which is 2.3 rounded to the nearest tenth.
Of course we also need to use our units miles, so 2.3 miles.
Hope this helps!
Answer:
150 red bars
Step-by-step explanation:
To solve this, you can use proportions. First, set up your two ratios (4:3 is equal to 200:___). Each ration represents the number of green bars to red bars. To get from 4 to 200, you can multiply 4 by 50. You could do the same to 3. 3 times 50 is 150, so there are 150 red bars.
