Answer:
y > -1/2 x + 4
Step-by-step explanation:
Equation of a line : (y-y1)/(y2-y1) = (x-x1)/(x2-x1)
(y-4)/(2-4)= (x-0)/(4-0)
(y-4)/-2 = x/4
(-y+4)/2 = x/4
-y+4 = 1/2 x
-y = 1/2 x - 4
y = -1/2 x + 4
the solutions of the inequality are the points above this line, so
y > -1/2 x + 4
Answer:
our inputs are 3 & 1/2
Step-by-step explanation:
the ? is the slope and the slope is equal to 1/2 so
?=1/2
the point slope formula is
(y-y1)=m(x-x1) (x1,y1)--> a point on the line m--> slope
so we chose (x1,y1) as (3,0)
when we plug that in we get
y-0=1/2(x-3)
so our inputs are 3 & 1/2
797,100 deaths x
---------------------------------- = -------------------------
350,000,000 people 100,000 people
or:
797,100 deaths x
--------------------------- = -----------------
3500 people 1 people
Result: 228 deaths per 100,000 people
Answer:
a = 3
b= -1
c = 5
X = (-b +- sqrt [b^2 - 4ac]) / 2a
X = (--1 +- sqrt (1 - 4*3 * 5)) / 2* 3
x = (1 += sqrt (1 -60)) / 6
x1 = (1 + sqrt (-59)) / 6
x2 = (1 - sqrt (-59)) / 6
