For a function to have a derivative in a point has to be continuous at the point, that is, it has to be defined at that point, other wise the derivative would be meaningless.
For dark line
Slope
Equation in point slope form
Put (0,0)
As line is dark sign is ≤
The inequality
For dashed line
Equation in intercept form
Put (0,0)
Symbol is >
Inequality is
Sum of 5 times z and 4 divided by two is 7.
Answer:
y = 5x+7
Step-by-step explanation:
Parallel lines have the same slope so y = 5x+9 is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is 5
The new line will have a slope of 5
y = 5x+b
We know a point on the line (-2,-3)
Substitute this point into the equation
-3 = 5(-2)+b
-3 = -10+b
-3+10 = b
7 = b
y = 5x+7
Answer:
$17.5
Step-by-step explanation:
50 is 1/2 of 100, so just divide 35 by 1/2
