Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Multiply by -1 both sides ( remember that the sign of the inequality change)
The solution is the interval ----> (-∞,-4]
All real numbers less than or equal to -4
In a number line the solution is the shaded area at left of x=-4 (close circle)
see the attached figure
Answer:
Graph # 3
Step-by-step explanation:
-2x + 5y > 15 Let x = 0 solve for y
-2(0) + 5y = 15 change the > to an =
5y = 15
y =3 Point (0, 5) is on the graph
Graph # 3 is correct because the y-intercept is 5
x y
0 3 -2(0) + 5y = 15; 5y = 15
5 5 -2(5) + 5y = 15; -10 + 5y = 15; 5y = 25; y = 5
10 7 -2(10) + 5y = 15; -20 + 5y = 15; 5y = 35; y = 7
The graph > the line is dotted and you will shade above the line
The formula for finding diameter from the circumference is d= c/3.14.
Using this formula, plug in your circumference, as shown below.
d=25/3.14
d=7.96
basically an independent variable is variation which does not depend on other words
