Answer:
Step-by-step explanation:
step 1
Find the slope of segment HI
The formula to calculate the slope between two points is equal to
we have
H (-4,2), and I (2,4)
substitute the given points
simplify
step 2
Find the slope of the perpendicular line to segment HI
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have
so
step 3
Find the midpoint segment HI
we know that
The formula to calculate the midpoint between two points is equal to
we have
H (-4,2), and I (2,4)
substitute
step 4
we know that
The perpendicular bisector of HI is a line perpendicular to HI that passes though the midpoint of HI
Find the equation of the perpendicular bisector of HI in point slope form
we have
substitute
step 5
Convert to slope intercept form
Isolate the variable y
step 6
Convert to standard form
where
A is a positive integer
B and C are integers
Adds 3x both sides
see the attached figure to better understand the problem
Answer:
54.1%
Step-by-step explanation:
From the table, the total number of patients with type-B blood is given as 183. On the other hand, the number of males with type-B blood is given as 99. The percentage of patients with type-B blood who are males can be calculated as;
(the number of males with type-B blood/the total number of patients with type-B blood) * 100%;
( 99/183) * 100 = 54.1%
Therefore, the percentage of patients with type-B blood who are males is 54.1
The system of equation to be graphed is the following :
And the solution is the intersection point of the two graphs .
Answer: Erica's Mother will donate $28.8
Step-by-step explanation:
As you can see we need to find out the amount of money her mother will donate if she bikes 18 miles so to figure that out we will need to divide the amount of miles by 0.25 that will give us 72. Now since we need to figure out how much money her mother will donate we need to multiply 72 by 0.40 that will give us 28.8.
